After a crash involving a bicyclist

Collision Bureau is not a law firm and this is not legal or medical advice. It is general information about what happens after a crash. For advice on your situation, talk to an attorney licensed in your state or a treating clinician.

The scene is a medical event before it is a claim

A bicycle crash with a motor vehicle looks like a pedestrian crash in one basic respect and like a two-vehicle crash in another. There is no steel between the cyclist and the car, which colors the scene medically. There is also a vehicle on the cyclist's side, which is a damaged piece of property that will enter the file along with everything else. The medical side comes first because bodies come first, and the paperwork follows the ambulance, not the other way around.

This section only exists to say the obvious out loud. If responders are on their way, nothing in a claim guide should move faster than they do. If a hospital trip is happening, that trip is the day's event. The paperwork a claim is built from is being created in the background by exactly the right people. Nothing in this article asks a person at a crash to prioritize evidence over care, and nothing in the next sections rearranges the order of medical first, claim later.

This guide describes what the paperwork does. It does not describe what any body needs. That is a clinician's jurisdiction, and the only sentence this site offers about care is the one on every medical page: get seen because you are hurt, not for a claim. The scene is a scene, the hospital is a hospital, and the rest of this article is about what the file looks like once both of those have happened.

Two kinds of readers find a page like this. One was riding and was struck. The other was driving and the cyclist they struck is a stranger who will become a claimant on their policy. The mechanics described below apply to both audiences in opposite directions. Nothing is written to help one side win against the other, and the site's position on that posture is in the footer disclosure.

What a bicycle crash file looks like

Insurance claim systems were built around vehicle-to-vehicle collisions, and a bicycle crash leaves a shape that only half fits those systems. There is one motor vehicle in the file instead of two, so there is one auto insurer in play on the vehicle side, one body shop estimate if the car is damaged, and no second insurer arguing about repair figures. On the cyclist's side, there is a bicycle, which is a vehicle that is treated under most state codes in general terms, and which is also, for claim purposes, a piece of personal property with a value and a condition that have to be documented.

What takes the place of a second body shop estimate is a bike shop estimate. A qualified bike shop inspects the frame, assesses the components, and writes a repair or replacement figure the way a collision shop would for a car. In many frame materials, a significant impact ends the useful life of the frame as a mechanical matter, which is a fact a shop assesses rather than a claim strategy. The resulting estimate becomes a document in the property-damage portion of the file, with the same role an auto estimate carries in a two-vehicle claim. This section's deeper look lives further down under the bike shop section.

What also fills the file is medical paperwork, assembled from the same stack of record types any injury claim produces. The treatment-gap mechanics covered in the treatment gap after a crash run with the same force here, and the clinical records and billing records travel the same chain described in why medical records decide injury claims. The bicycle wrinkle inside those records is the mechanism of injury, which a chart tends to describe with more detail in bicycle cases than in low-speed vehicle crashes because the mechanics matter clinically. More on that in the mechanism section below.

Then there is the scene, with its own set of documents. Lane markings and the presence or absence of a bike lane, intersection geometry, sightlines, parked cars, lighting, the specific point of impact on the vehicle, and any damage pattern that connects the two. Each is a fact in the file if someone captures it on the day. None of it captures itself, and much of the scene changes within an hour as traffic resumes and the physical traces disperse.

The last thing a bicycle file has that a vehicle-only file does not is a damaged piece of apparel and gear. Cycling clothing, shoes, a helmet, lights, a bike computer, panniers, and anything inside the panniers can all come out of a crash broken, torn, or lost. Each of them is personal property, each is documented by purchase receipts and photographs where available, and each enters the property-damage portion of the claim.

The driver's auto insurance covers more than people expect

Here is the first fact that surprises people on both sides of a bicycle crash. A standard auto liability policy, in general terms, is written to cover the people the driver is legally responsible to for injuries and property damage arising out of the operation of the vehicle. The policy does not require those people to be in another car. A cyclist is a covered third party under the driver's liability coverage the same way a pedestrian is, the same way a motorcyclist is, and the same way a passenger in another vehicle is. The absence of a second car on the cyclist's side does not remove the coverage. It only removes the second insurer from the room.

What the driver's liability coverage pays for, in general terms, falls into two buckets. Bodily injury coverage addresses the cyclist's injury-related losses: medical costs, lost income, and the categories the policy and state law describe. Property damage coverage addresses the cyclist's personal property that got broken, torn, or lost in the crash: the bike, the helmet, cycling clothing and shoes, lights, a bike computer, panniers, and anything inside them, including whatever the cyclist was carrying for a destination that no longer matters.

Two numbers on the driver's policy matter later, and both live on the declarations page the driver received when the policy was issued. The first is the per-person limit on bodily injury, which caps what any one injured person's claim can recover from that policy. The second is the per-accident limit, which caps the total across all injured parties in one event. State minimums vary. What any specific limit means for a specific claim is a legal question, and it is the question a licensed attorney is paid to answer.

Coverage on the driver's policy	What it generally does in a bicycle case
Bodily injury liability	Primary source for the cyclist's injury losses, within the policy's per-person and per-accident limits.
Property damage liability	Addresses the bike, helmet, apparel, lights, computer, panniers, and other personal property damaged in the crash.
Medical payments coverage, where carried	Can pay for medical costs regardless of fault, up to the limit. Terms depend on state and policy.
Personal injury protection, where applicable	In some states, PIP on the driver's policy can reach cyclists struck by the vehicle, under the state's rules.
Umbrella policy, if the driver has one	Can sit above the auto policy's limits in some cases. Existence, terms, and triggers vary.

General descriptions only. What any coverage does in a specific claim depends on the policy, the state, and the facts of the crash. Not a coverage opinion.

The driver's insurer does not generally function as an on-demand payer for a cyclist's bills as they arrive. In a liability claim, the pattern is more often one resolution later, built from a complete file, rather than ongoing bill payment through the open period. That has consequences for how bills get paid in the meantime, which is why the next two sections exist. Nothing in this paragraph predicts anything about any specific claim.

The cyclist's own auto policy as a second layer

A cyclist's own auto policy, if any, can still enter the file even though no car of theirs was in the crash. Several standard coverages on an auto policy are written in general terms to apply to the people the policy covers, in situations the policy describes, without a requirement that the covered person be in a car at the moment. The three that come up are medical payments coverage, personal injury protection, and uninsured-motorist coverage.

Medical payments coverage, where it exists on a policy, is a per-person limit that generally pays medical costs regardless of fault, up to that limit. Many policies cover the policyholder, resident family members, and sometimes additional listed persons when any of those people are injured by a motor vehicle, including while riding a bicycle. Which specific policy says that, and what the exact scope is, is a reading of a specific document. The declarations page shows whether the coverage exists and at what limit.

Personal injury protection is state-dependent in its very existence. Some states require it, some permit it, some do not have it at all. Where PIP exists, it is a no-fault coverage with broader reach than MedPay, often including medical costs and sometimes lost income and other categories, up to its limit. The language on most PIP policies, in general terms, reaches people the policy covers when they are injured by a motor vehicle, including as cyclists. Which state's version applies, and what each category inside PIP covers, is state-specific and policy-specific and belongs to a licensed attorney in your state.

Uninsured and underinsured motorist coverage is the quiet layer that saves some bicycle cases from becoming nothing. If the driver carried no insurance, or carried too little, uninsured-motorist coverage on the cyclist's auto policy generally applies to injuries caused by that driver, in situations the policy describes, including hit-and-run events the policy addresses by name. UIM, the underinsured version, picks up the difference between the driver's limit and the covered person's own limit, in general terms, where state rules permit it in that form.

The common mistake, from the cyclist's side, is to assume no auto coverage applies because no car was involved on the cyclist's end. The common mistake, from the driver's side, is to assume the cyclist has no coverage of their own. Both assumptions can be wrong on the same file. The paperwork that answers either question is a declarations page, which is a document the policyholder owns and can request from their carrier if a copy is not already on hand. What any of this means for a specific claim is, as always, a licensed attorney in your state.

Right-hook and doored, in general terms

Two geometries show up often enough in bicycle crashes that they have names, and the names are useful in a general-information article so long as they stay neutral. Neither word is a verdict, neither word by itself tells a claim story, and both appear in investigator reports as descriptions of what happened rather than as findings about who was wrong.

A right-hook, in neutral terms, is a geometry where a vehicle turning right crosses a cyclist traveling straight along the vehicle's right side. The scenario puts a cyclist in a vehicle's blind spot or across a lane the driver was leaving as the cyclist arrived in it. The specific sub-geometries vary with the lane configuration, the presence or absence of a bike lane, the signal state, and where each party was in the moment. Investigators recognize the pattern and know the standard questions to ask: speed, turn signals, lane position, mirror check, visibility, and the exact sequence of events in the five seconds before contact.

A dooring, in neutral terms, is a crash in which a parked vehicle's door is opened into the path of a cyclist traveling along the vehicle's left side. The pattern is specific to door-zone cycling, which is itself a term for riding within the arc a door covers when opened. State codes vary on parked-driver duties to look before opening, on cyclist duties to leave door-zone room, and on the specific standards an investigator applies to the geometry. The crash itself tends to leave physical evidence: paint transfer, bent door hinges, and the specific damage pattern on a frame struck at that angle.

Both geometries end up as facts in a file, documented through the police report, through photographs, and through whatever the vehicle and the bike show as physical evidence. Both appear in medical records as mechanisms of injury described by the clinician. Neither word determines the outcome of a claim by itself, and this guide is going to say that at the end of every geometry section because the fact of a named pattern can mislead people into thinking the pattern is the answer. The pattern is a description. The answer is a legal reading of the state's rules against the specific facts, performed by a licensed attorney.

A third geometry worth naming briefly, because it comes up often in neighborhoods with angled parking and in commercial strips, is the exit-driveway crash. A vehicle leaving a driveway or a parking lot crosses a sidewalk and a bike lane in sequence, and a cyclist traveling along either can meet the vehicle at the exit point. The specific duties, sightlines, and yield rules in that scenario depend on the state's framework and on the roadway geometry. Investigators recognize it, officers often diagram it carefully, and the file reads it the same way the file reads any other geometry: as facts weighed against the state's rule.

None of these named geometries is an exclusive category. Real crashes often sit between patterns, carry elements of two or more, or involve maneuvers that have no standard name. The named patterns are useful because they let reports describe common scenarios efficiently, and because they let investigators ask standard questions quickly. They are not useful as predictions. The names describe. The reading decides. That sequence holds for every pattern a bicycle crash file might carry a label for.

Visibility arguments as mechanics

Visibility is a word that gets used two ways in bicycle cases, and it is useful to keep the two separate. The first use is mechanical: whether the cyclist was physically within the driver's line of sight at the moment of the crash, taking into account time of day, weather, lighting, lane position, parked cars, signage, and anything else that affects what a human in a vehicle can see. The second use is normative: whether the cyclist had taken the kinds of visibility measures that a given state's framework references, including lights, reflectors, and in some states high-visibility apparel. The two uses can run in different directions in the same file.

In general terms, state codes require lights at night on a bicycle, often with specifications on front white and rear red lighting, and often with reflector requirements as well. Daytime requirements are rarer and vary. The question of whether a cyclist was running lights at the moment of a crash is answered by facts that enter the file through the police report, through physical evidence on the bike, and sometimes through the cyclist's own account. A missing or non-functional light is a documented fact, not a conclusion, and what the state's rule does with that fact varies.

Mechanical visibility is more layered. A cyclist in a dark lane with no streetlight, in black clothing, with no light, is a different mechanical picture from a cyclist in a lit lane with a flashing white front light. Both are facts that enter a file, and both are read against the geometry of the crash itself. A driver who turned right across a cyclist with proper lighting and a visible position in the lane is a different file from a driver who failed to see a cyclist riding in blackout conditions at speed. The reading between those two silhouettes is the whole job of the people who evaluate the claim.

This section is description of mechanics, not advice about what to ride with. The site does not run a safety campaign on this page, and the only directive on any page about care says, again, that medical visits are a decision between a person and a clinician. On the equipment side, the general-information point is that lights and reflectors are both legal requirements in many conditions and documented facts in a crash file, and the facts land in the file whether anyone talks about them or not.

Visibility fact	Where it tends to land in the file
Time of day and lighting conditions	Police report, scene photographs, and ambient weather and sunset data for the location.
Lights and reflectors on the bike	Physical inspection by officer or shop, photographs, and often the cyclist's own account.
Clothing and reflective gear	Observed by responders, photographed where possible, and sometimes retained as physical evidence.
Line-of-sight obstructions	Parked cars, foliage, signage, and other scene features documented in the diagram and photographs.
Driver attention indicators	Observations by responders, witness statements, and in some cases phone records obtained through legal process.

General descriptions of where visibility facts tend to be captured. Not a checklist and not a legal analysis.

The helmet documentation question

Helmets attract more questions in bicycle cases than any other single piece of equipment, and the question is more complicated than any one answer. This section describes the mechanics in general terms, and it ends where every other section ends, which is at a licensed attorney in your state. Nothing in this page is a position on whether anyone should wear a helmet. That is a safety discussion that lives on other pages, run by other organizations.

In general terms, state helmet laws vary considerably. Some states require helmets for riders under a certain age, some have no mandatory law for adults, and some localities impose rules of their own on top of state law. The age thresholds, the specific vehicle class covered, and the civil consequences of a violation all depend on the state. The question of whether a helmet was worn is generally recorded on the police report where the officer observed it, and the helmet itself may be collected or photographed as physical evidence if it was damaged.

Beyond the rule-of-the-road question is a separate question that varies even more by state: whether and how the absence of a helmet can affect a civil claim. Some state frameworks treat the question one way, others another, and a few have statutes or case law specifically on the point. This is not a universal rule, and any article that tells you otherwise is making a jurisdictional claim it cannot support. What a specific state does with the question is exactly what a licensed attorney in your state reads, from the state's actual sources.

The documentation side is simpler and worth describing. A helmet that was worn in a crash with any impact is generally treated by manufacturers and shops as having completed its useful life, which is a mechanical observation about helmet construction, not a legal one. For claim purposes, that observation makes the helmet a piece of property-damage evidence with a documented history, usually by the shop or the manufacturer the cyclist later consults. Replacement cost of a helmet, like the replacement cost of any piece of gear, is documented through purchase records.

The bike is evidence as well as transportation

In the first hour after a crash, the bike is often moved, propped up against something, loaded into a vehicle, or picked up by a shop or a tow operator. From that moment forward, the bike is also a document, in the sense this guide has been using the word: it has a dated condition that corresponds to the moment of the crash, and anyone reading the file later will want to know what that condition was.

Photographs taken at the scene, before anything is moved more than has to be moved for safety, are generally the richest record of the bike's crash-moment state. Angle, position relative to the vehicle, specific damage areas, missing or bent components, and the configuration of lights and reflectors are all facts that photographs can carry forward with dates attached. Nothing in this paragraph asks anyone to prioritize photography over care. It names the category of record because without it, the bike's condition exists only in the memories of whoever was present.

After the scene, the bike's story continues at wherever it ends up: a bike shop, a garage, or a storage lot. A bike that goes directly to a qualified shop generally produces a dated inspection record, including an estimate for repair or replacement, which is the central document in the property-damage portion of the file. A bike that sits in a garage for weeks produces no record during that time, and the gap between the crash and the shop inspection is noticed by the people evaluating the file in the same way other documentation gaps are noticed.

The paper handling of the bike itself is specific. A frame struck in a significant impact may be unsafe to ride even when it appears intact, which is a mechanical observation shops are trained to make and insurers are familiar with. In those cases, the shop's recommendation generally shifts from repair to replacement, and the estimate reflects a replacement figure. What the estimate says, what the carrier does with it, and how the valuation is resolved are standard property-damage mechanics in the same shape as a vehicle total-loss conversation. The companion guide how a total loss number gets decided covers the vehicle version of that conversation, and the bike version runs on similar logic with different sources.

Bike equipment valuation

Bikes and their accessories span a cost range wider than most non-cyclists imagine, and a crash can involve equipment anywhere on the range. A city commuter with a mechanical drivetrain is one file. A performance road bike with electronic shifting and carbon wheels is another. An e-bike with a complex drive unit is another. All three are personal property in the eyes of a property-damage claim, and the specifics of each are documented differently.

Documentation of value runs through three categories, in general terms. The first is original purchase records: the receipt, the credit card statement, the account history with the retailer. Those documents establish that the bike existed at a price point. The second category is condition records: photographs from before the crash, service records from a shop over the life of the bike, upgrade receipts for components added later. Those documents establish that the bike was in the condition the claim describes. The third category is replacement research: current pricing for the same or comparable models, documented at the time of the claim, generally through the shop writing the estimate.

Accessories matter too, and most of them come with receipts if people keep them. A helmet, cycling shoes, cycling-specific clothing, lights, a bike computer or GPS head unit, pedals that are not original, a saddle that was upgraded, panniers or a bag, and anything inside the bag at the time of the crash. The combined value of accessories on a well-equipped bike can rival the value of the bike itself, which is not a cheerful fact in a crash but is a documented one in a claim file.

Item category	Documentation that supports valuation
Bike frame and original build	Original purchase receipt, serial number records, model year documentation, shop service history.
Upgraded components	Receipts for upgrades, shop service records, photographs showing the components installed before the crash.
Helmet	Purchase receipt, make and model documentation, condition after the crash as recorded by the shop.
Lights and electronics	Receipts, make and model records, functional status before and after the crash.
Clothing, shoes, and bags	Receipts, photographs, and physical items retained where possible.

Illustrative categories, not a complete inventory for any claim. Specifics vary by bike and by what the cyclist was using at the time.

The e-bike category deserves a separate note. Electric-assist bicycles sit in a specific regulatory bucket in most states, and their drive units, batteries, and electronics add components that are more expensive and more specific than those on a non-electric bike. The valuation and inspection of an e-bike after a crash often involves the manufacturer or an authorized service point, and the paperwork reflects that complexity. The claim mechanics are still the same mechanics; the stack of records is just thicker.

One quiet valuation point that comes up in bicycle claims and almost never comes up in car claims is the market for used bicycles. A specific used bike has a value that lives in the actual transactions of people trading in or selling bikes of that model, and the online marketplaces where those transactions happen are a kind of valuation evidence. A shop writing an estimate often cites that market, and a cyclist assembling documentation can keep screenshots of comparable listings at the time of the claim. The vehicle world has formal valuation guides that do this work for cars. The bicycle world does the same work less formally, through shops, forums, and listings, and the paperwork a claim produces reflects that difference.

Another valuation point worth stating is that bicycles depreciate differently from cars. A high-end road bike that is 3 years old can retain a substantial share of its original value, especially if components have been maintained or upgraded. A low-end commuter bike can lose most of its value in a season. Those facts affect how a replacement figure gets built, and they affect how a dispute over the figure gets argued. Documentation of the specific build, the specific service history, and the specific condition at the time of the crash is what pulls the valuation out of the general and into the specific.

The bike shop as the equivalent of a repair facility

In a two-vehicle crash, the body shop that inspects a damaged car writes the estimate that drives the property-damage portion of the file. In a bicycle crash, the bike shop plays that role for the bike and its accessories. The parallel is tight enough that it is worth stating directly: a bike shop producing a post-crash inspection and estimate is doing, for a bicycle, what a collision shop does for a car. The companion guide how a collision repair estimate works describes the vehicle version of this process in detail; the bike version runs on similar logic with different sources.

What a bike shop inspection generally covers: a frame assessment, including whether the frame material shows any indicators of impact damage; a component review across the drivetrain, wheels, braking system, and cockpit; a check of the headset and bottom bracket for integrity; and a functional review of lights, electronics, and any e-assist system. The shop then produces an estimate, which may be for repair, for replacement of specific components, or for complete replacement of the bike where the frame is not safe to ride.

Shops that handle crash inspections regularly tend to have language for their estimates that insurers recognize. The specific wording of a replacement-cost estimate versus a repair estimate matters in a property-damage claim the same way it matters in a vehicle claim. Nothing in this paragraph is a recommendation about where to go for an estimate; Collision Bureau does not rank, rate, or recommend providers in any category, and the choice of shop is the cyclist's to make. What is accurate to describe is that a shop estimate becomes a document in the file, and the clarity of the document shapes the conversation it supports.

The handling of the estimate against the carrier's position runs on standard property-damage mechanics. The carrier may accept the shop estimate as submitted, may ask questions about specific components, or may propose a different number. Property-damage valuation disputes have their own paths to resolution, which are covered in general terms in the diminished-value guide for one specific flavor of the discussion. The bicycle version of these disputes has fewer standard tools than the vehicle version does, which is one of the reasons documentation matters as much as it does.

A note on what the shop cannot do, because it belongs in a guide that keeps the roles straight. A shop assesses the bike. A clinician assesses the cyclist. An adjuster evaluates the file. An attorney reads the state's rules against the specific facts. The four roles are each a different jurisdiction, and this guide draws the lines deliberately. The shop's job starts and ends with the bike, and nothing in a shop estimate is a legal position or a medical observation.

Documentation habits for bicycle cases

If you are reading this section after the first hour has passed, this is still useful. A bicycle case file assembles from a short list of categories, and keeping the categories together saves work later.

Physical items destroyed in the crash are evidence as well as personal loss. A torn jersey is a document of the body's position; broken glasses are a document of head motion; a cracked helmet is a document of head impact. Repair receipts and replacement receipts matter for the property-damage portion of a claim, and the physical items matter if the file ends up needing to describe mechanics. None of this is a hoarding instruction, and nothing in this guide asks anyone to keep items that are legitimately garbage. The point is that items with evidentiary value are a category worth being aware of.

Medical paperwork accumulates in two places. With the providers themselves, where the chart notes sit and move only on authorization. And in your own hands, where discharge paperwork, follow-up slips, bills, explanations of benefits, and pharmacy receipts arrive. What you can keep is everything that arrives at your door with your name on it. That stack ends up in front of a licensed attorney eventually if the claim progresses that far.

Communications become documents. Any letter or email from an insurer, any voicemail from an adjuster, any text message from someone involved at the scene. The question of what to say to any adjuster is a question for a licensed attorney, not for a page like this, and the adjuster is not your adjuster is a separate guide in this library that describes which insurer's representative is calling and in what role.

A personal timeline, written for yourself and no one else, is a documentation habit worth having. Where you were going, what time it was, what you remember of the scene, when you first spoke to the police, when you first spoke to a provider, when a bill arrived. Memory is a resource that depletes, and a dated contemporaneous note stays accurate longer than recollection. What any of that is used for later is attorney work. The point here is that the note is a record of the kind this library runs on.

How fault is examined, in general terms

Fault in a bicycle case is a legal reading built on facts, and the reading happens in rooms far from the lane. Officers at a crash may form impressions and may record a citation, insurers may form impressions on their first look at the file, but the final answer to who was at fault, in what share, with what legal consequence, is a reading that happens inside a claim resolution or a court. This section stays general on purpose.

The general shape of a fault examination in a bicycle case runs through a short list of questions. Where were the cyclist and the vehicle at the moment of impact, and what rules apply in that geometry under the state's framework for bicycles on roadways. What was the driver doing immediately before: speed, attention, phone, impairment where documented. What was the cyclist doing: direction of travel, lane position, lane choice, signaling, lights and reflectors, visibility conditions. What third-party evidence corroborates any of these facts. The file answers each question with the records available, and the answers are weighed against the state's rule on divided fault.

The state's rule is the piece this guide refuses to pretend it can summarize. Some states apply pure comparative fault, allocating recovery by the percentage of fault assigned to each party. Some states apply modified comparative rules that bar recovery at a specific threshold. A few states apply contributory negligence rules that bar recovery at any share of fault assigned to the claimant. The differences are enormous in practical effect, and a claim that goes one way in one state can go another way in the next state over. A general reference on the companion topic of claim deadlines lives at law.cornell.edu/wex/statute_of_limitations; the fault framework for your state is a question for a licensed attorney in your state.

A reading pattern worth stating: a bicycle case rarely has an all-or-nothing fault profile. More often, a mix of facts carries some weight on each side, and the whole evaluation is about where the mix lands. That is why the records matter in the volumes they do, and why first-hour evidence described earlier moves files in a way almost nothing else moves them. A clean record of the geometry, the lighting, and the position of the vehicle at the moment of impact is worth more than any eloquence after the fact.

The medical record and the mechanism

In a bicycle injury file, the medical record carries the mechanism of injury: how the injury happened, as described to a clinician at the first visit, in the clinician's own words. That description is a sentence or two in the chart, and it is the sentence every later reader of the file returns to when asking whether the injury connects to the crash. The onset discussion in the treatment gap after a crash applies with full force here.

Mechanism language in a bicycle case tends to be specific because the geometry is specific. The chart might describe being struck by a turning vehicle on the right side, being thrown over the handlebars, being doored, landing on a specific body part, or being dragged a specific distance. All of that goes into the record because a clinician needs it for treatment, not because anyone is building a claim. The byproduct is that the chart becomes a dated, independently authored description of the physical event, which is the kind of document a later reader cannot manufacture.

The downstream reading of the mechanism depends on what the file is for, and this guide does not predict any specific reading. In general terms, consistency across records matters more than any single phrase, and gaps and silences get read exactly the way they are read in the main treatment-gap guide. The reading of records in a bicycle claim is the reading of records in any injury claim, with the specific detail that the mechanism is more easily tied to the crash by the geometry involved and by the physical evidence on the bike.

One more time, because the medical lane requires repetition: nothing in this section tells anyone what care to seek or when. Clinicians answer that, this website never answers it, and the records exist to document what honestly happened and when. Get seen because you are hurt, not for a claim. That is the only medical sentence this site ever gives.

The clocks a bicycle case runs on

Several clocks start at the moment of a bicycle crash, and they run on different schedules. This section lists them in general terms. Specific state deadlines and specific contract clocks belong to the paperwork of your situation and to a licensed attorney in your state.

The medical clock is the one the treatment gap after a crash describes in full. It is the distance between the crash date and the first dated medical record, and it keeps running until a record ends a silence. An ambulance ride to a hospital generally produces a same-day record on the day of the crash. A cyclist who declined transport, walked the bike home, and waited to see how the body felt has started the gap clock without necessarily meaning to.

The statute of limitations is the one legal deadline this guide names, and it varies by state. The length of time to file a claim or lawsuit for personal injury is state law, and the general shape is that two years is common and some states allow less. Missing the deadline generally bars a claim regardless of merit. A consumer-grade reference is at law.cornell.edu/wex/statute_of_limitations; the exact rule for your state is what a licensed attorney reads.

The notice clock, where it exists, is a separate deadline that attaches to specific defendants and specific claim types. Claims that involve a government entity, a public transit vehicle, or a municipal roadway sometimes carry short notice deadlines that run from the date of the crash, and the clock is often much shorter than the ordinary statute of limitations. The existence, length, and recipients of a notice requirement vary dramatically by state and by defendant type. This guide names the category to prevent a surprise. The actual timing is attorney territory.

The property-damage clock for the bike is the quietest clock in a bicycle file. The bike sits where it sits, and the longer the inspection and estimate wait, the more documentation gap accumulates on the property-damage side of the record. There is no statute attached to that clock, in general terms, but there is a set of practical consequences for how a shop can assess condition and attribute damage to the crash versus to anything else that happens to a bike that is being ridden or stored in the interval.

The rooms the file travels to

A bicycle injury claim can resolve cleanly on a clean file, or it can travel into rooms the first week never hints at. Knowing the rooms exist is general information, and it completes the picture of why the records in the first weeks carry weight.

The first room is the reserve inside the driver's insurer. Claim files get a dollar reserve set early, based on what the file suggests, and the reserve adjusts as records arrive. Reserves are internal and nobody outside the carrier ever sees them, but they shape how the file is handled from the inside. The records that arrive in the first weeks have outsized influence on the initial figure. This is the room where early documentation does its quietest work.

The second room is the evaluation that happens when the file moves toward resolution. A resolution conversation starts from a written summary of the records: the medical stack, the police report, any available third-party evidence, the shop estimate for the bike, the policy limits, and the facts the file established about the scene. A bicycle claim often ends at this room on the strength of what the records say.

The third room is a potential independent medical examination, which is covered in general terms in the treatment gap after a crash. The specific bicycle wrinkle is that the mechanism of injury is often central to the exam, and the bicycle-crash mechanism tends to produce a wider set of possible injuries than a low-speed vehicle collision. What rights attach to one in your state is a legal question.

The last room is a dispute, where the file's contents become evidence. Most bicycle claims resolve before this room; some do not. The important observation is that the file is the same file either way, and the records that mattered in the quiet rooms are the records that matter here.

One procedural wrinkle in a bicycle case that is worth stating before leaving this section: the vehicle on the driver's side may be of interest later, and the condition of the vehicle at the time of the crash is captured in the same photographs and shop or body-shop records a vehicle claim produces. The paint-transfer, the door-edge marks, the fender dent, the mirror scrape, each is a dated piece of physical evidence that corroborates or complicates the geometry the file describes. The driver's side of the file holds those records, and the cyclist's side reads copies when a case progresses far enough to need them.

A quieter observation about the rooms is that most bicycle cases do not travel to all of them. The majority of files that resolve do so without an independent medical examination and without a formal dispute, and the mechanics of the earliest rooms are therefore the ones that matter most to most claims. That is one more reason the first weeks of record-keeping do a disproportionate share of the quiet work of a case, and one more reason the general-information posture of this guide ends at the same place every section does: the specific decisions in a specific file belong to a licensed attorney in your state, reading your actual records against your state's actual rules.

What the assembled file looks like

Zoom out from any one record and the file as a whole has a predictable shape by the end of the first weeks. There is a police report with a date, a diagram, and a narrative. There are scene photographs, taken by whomever took them. There is a medical record stack beginning with the first dated chart. There are explanations of benefits from a health insurer. There is a shop estimate for the bike, with its own date. There are receipts and photographs for the accessories and clothing. There is correspondence, in letters and emails, between each party and each insurer. The file is the sum of those documents.

Reading from the cyclist's side, the file is a partial file. The cyclist or an attorney for the cyclist holds the medical paperwork, the shop estimate, the receipts, correspondence, and whatever has been obtained of the police report and the independent documents. The cyclist does not hold the driver's carrier's internal notes, which live inside the carrier and are not shared in general terms outside the ordinary processes a dispute would use. The driver's side holds its own file, with its own private layers and shared independent documents.

The driver's side of the file

This guide reads from both sides, and the driver's side owes its own description. A driver involved in a bicycle crash is a party to the file as surely as the cyclist is, and the mechanics the file runs on do not change based on which side a reader is on. What changes is who is building what, and which paperwork lands on which doorstep.

A driver's first paperwork task is generally to notify the insurer, under the terms the policy sets. Most auto policies include a cooperation clause and a prompt-notice provision, and the policy document itself describes the specifics. Notifying the insurer opens a claim file on the carrier's side, assigns it to an adjuster, and sets in motion the carrier's own investigation. From the driver's standpoint, the carrier is on the hook to defend covered claims within the policy limits and to pay covered claims as the policy describes. The exact scope of the defense and the exact handling of a specific claim depend on the policy and the state.

What a driver's insurer does during the open file includes work that happens quietly on the inside: setting a reserve, requesting the police report, interviewing the driver about the facts, and in general terms, speaking with the cyclist or the cyclist's attorney about the claim. A driver's own statement to the carrier is a different conversation from a statement to the other side's carrier, and the adjuster is not your adjuster describes who is calling and in what role. The underlying point for a driver is that cooperating with your own carrier is a contract obligation, and the specifics are read against your policy by a licensed attorney where the stakes warrant it.

Policy limits enter the driver's picture as a specific fact worth knowing. The per-person and per-accident bodily injury limits on the driver's auto policy are the ceilings the insurer's defense and payment obligations are organized around. Where the exposure in a claim exceeds those limits, the driver's personal interest can diverge from the insurer's interest in ways that get complicated quickly. This paragraph does not describe how to handle any such situation; it names the category so that a driver reading this guide knows the first conversation with a licensed attorney of their own, separate from the insurer-provided one, is a conversation that exists.

Vehicle damage on the driver's side runs on standard mechanics. A dent and scuff from a bicycle impact tends to be a minor repair, and in some crashes the driver's vehicle has no visible damage at all. In other crashes the damage pattern on the vehicle, including scrapes on a door panel from a dooring and dents on a front fender from a right-hook, becomes a dated piece of physical evidence that the file reads along with everything else. Photographs of the vehicle after the crash matter in the same way photographs of the bike do. The condition is a dated fact, captured or not captured.

What this section is not is any kind of script. Nothing in it tells a driver what to say to anyone. The conversations after a bicycle crash are legal conversations whose shape and timing belong to a licensed attorney in your state. The general shape above is description: a driver's policy obligates certain cooperation, a carrier runs an investigation, and the exposure sits inside the limits the policy was issued at. Everything specific to any crash is specific, and specific is attorney territory.

How this site handles a bicycle request

Collision Bureau makes one request cover the categories a crash broke, and a bicycle crash is handled the same way everything else is. Reporting a bicycle crash on our form routes you to the categories you select. If an attorney is one of the categories, participating attorneys in your state hear from us. If a car on your side needs a tow or a repair, those categories hear from us. If a rental is one of the categories, same. The bike shop side can be coordinated with an attorney in the ordinary way; shop referrals are not themselves a Collision Bureau category because we do not rank, rate, or recommend providers in any category. Medical routing is the one lane that only happens when you explicitly ask for care.

The participation standards are published, and nothing more than participation should be read into a provider's presence. Using Collision Bureau costs you nothing. Providers pay us a flat fee for the connection, that fee never depends on what any claim is worth, and nothing is ever taken out of a settlement to pay us. The reason to spell that out in a bicycle article is the same reason to spell it out anywhere else: you now know how much weight files and records carry, and you should know that nothing about our fee gives us any stake in what yours say.

If you reach the form and are not sure what you need, nothing routes anywhere until we confirm the categories with you on the call. The same answer applies on the phone at (877) 66-COLLISION. The call is where unsure lands, because the week after a crash is not a week for guessing. The categories you tell us about are the only categories that hear from anyone, every time.

Which professional answers which question

A bicycle crash generates questions in four jurisdictions, which is one more than a pure vehicle crash because the bike itself has a professional attached. The body has a clinician, the claim has an attorney, the insurer's representative has a job that is not advising you, and the bike has a shop. Keeping the four desks straight prevents most of the common confusions.

The question	Where it belongs
Am I hurt, and what does my body need?	A clinician. Nobody else, and never this website.
Is the bike safe to ride and what is it worth?	A qualified bike shop, in writing, with photographs.
Whose insurance pays what, and in what order?	A licensed attorney in your state, reading your actual policies.
What does my state's fault rule do with these facts?	A licensed attorney in your state.
How are bicycle cases handled in general?	General information. This page, and the rest of this library.

A routing of question types, not advice about any answer. Legal questions resolve to a licensed attorney in your state.

Every hard question in this guide resolves to the same place: the process described here, in general terms, and a licensed professional answering the question for your situation. That is not a limitation of the guide. It is what general information can honestly be, and the first conversation with a licensed attorney is where your version starts. The cost of asking that conversation is zero.

If this is your week

The rest of the aftermath is one request.

One request covers the attorney, the tow, the repair, and the rental. It costs you nothing, ever.
