What to do after a bicycle accident
Reviewed by the Learn Injury Law editorial team
After a bicycle accident, move to safety, call 911 if anyone is injured, and photograph the entire scene — including your bike damage — before anything gets moved. If a vehicle hit you, get the driver's information and a police report number immediately. See a doctor within 24 hours even if you feel fine, because head injuries, spinal damage, and internal bleeding develop gradually. Your bike is evidence — preserve it.
Get Safe, Get Help, Assess the Damage
Move out of traffic immediately, check yourself for injuries, and call 911 if anyone needs paramedics — creating an official medical record on scene protects both your health and any future legal claim.
Adrenaline masks pain — injuries that feel minor now become serious within hours. Check your head, skin for abrasions or bleeding, limbs for anything that won't move right, and torso for pain when you breathe. If you or anyone else is injured badly enough that you can't walk or handle the next steps, call 911 immediately.
Once paramedics have cleared everyone, examine your bike for damage but do not move it unnecessarily — it is evidence. If you're in the roadway or in traffic, move to a safe spot immediately. If you can stand and your bike is movable, get yourself and the bike out of the way.
If anyone else is involved — another person on a bike, a pedestrian, a driver from a car — check on them too. Look at your bike. If it was hit by a car or fell hard, it is damaged in ways that aren't immediately obvious — frame cracks, bent wheels, brake issues. Don't try to ride it yet.
Secure the Scene and Document It
If a vehicle hit you, get the driver's name, phone number, email, driver's license number, license plate, and insurance policy number — call police and file a report with a report number.
If the driver left the scene, that's a hit-and-run. Report it to the police immediately. A hit-and-run is a separate crime in every state.
Photograph everything. Use your phone. Take photos of your bike from multiple angles, showing any damage clearly. Take photos of the roadway if it's relevant — the bike lane condition, any hazards, the road surface. If a vehicle was involved, photograph it if it's still there. If there are skid marks or road damage that shows impact, photograph those. Take photos from the driver's perspective and from your perspective, so there's a record of what each position could see.
Get witnesses' information. If someone saw what happened, ask them what they observed. Get their name and phone number.
The Bike Is Evidence — Preserve It
Photograph your bike's damage in detail before anything is touched, and preserve damaged components if the bike gets repaired — the damage patterns document exactly what happened in ways photos alone cannot capture.
Get photos from multiple angles, close-ups of the damage points, and overview photos showing the whole bike. If you have the bike repaired, keep the damaged components if the shop removes them. Keep receipts for the repairs. The cost and extent of the damage becomes relevant to your claim if someone caused the accident. Your attorney may want to examine the bike or the photographs or get a specialist to assess the impact.
Insurance, Your Own and Possibly Theirs
If a car hit you, claim against the driver's auto insurance for your injuries and property damage — your health insurance covers medical treatment, but it won't cover bike repair or replacement costs.
Some states allow cyclists to claim under the other driver's uninsured motorist coverage even though you're on a bike, not in a car. Other states have specific rules about how cyclists fit into the auto insurance system. If the driver is uninsured or underinsured, your own auto insurance's uninsured motorist coverage might protect you — but only if you have a car and carry that coverage.
Call an attorney who handles bicycle accidents and ask about your options. They can tell you what claims are available in your state and whether you're likely to recover costs for medical treatment, lost wages, or property damage.
Medical Attention — Especially Without Obvious Injuries
See a doctor within 24 hours even if you feel completely fine — head injuries, spinal damage, and internal bleeding often feel minor in the first hours but become serious later, and a documented baseline connects later symptoms to the accident.
When you see the doctor, be specific about what happened. Tell them about any part of you that hurts, any part that feels numb or tingly, any headache or dizziness. If you hit your head, even if the helmet protected you, mention it. If you have an existing medical condition that might be relevant, mention that too.
And if you feel fine? Go anyway. Getting cleared by a doctor creates a documented baseline. If symptoms develop later — sometimes weeks after an accident — that early evaluation shows that you were checked and monitored, which creates a timeline connecting the injury to the accident.
Keep all your medical records and receipts, including bills for the doctor visit, any imaging, any follow-up appointments, and any physical therapy. If you were injured badly enough that you miss work, get documentation from your employer or your doctor showing the dates you couldn't work.
The Unique Complications of Bike Accidents
Drivers have a legal duty to see you and not hit you — even if you violated traffic laws, they're still liable for hitting you. Your recovery depends on your state's comparative negligence rules, and helmet use affects claims differently in different states.
Cyclists and cars share the road, but you're occupying very different legal positions. Drivers are expected to see cyclists, to give them space, and to follow traffic laws around them.
Even if you were violating traffic laws or riding in a way that wasn't perfect, the driver still had a legal responsibility not to hit you. Most states follow comparative negligence, which reduces compensation by your percentage of fault but doesn't eliminate the driver's liability. If the driver was 80% at fault and you were 20% at fault, you recover 80% of your damages. A few states follow contributory negligence, which bars recovery if you were at all at fault. You need to know your state's rule.
If you weren't wearing a helmet, that will come up in a claim. In some states, helmet laws apply to cyclists of certain ages, and violating that law might reduce your claim. In other states, helmet use is irrelevant to legal liability. Insurance companies will ask, and they'll factor it in. This is another reason to talk to an attorney — they explain how your specific state treats helmet use in claims.
Bike Lanes, Road-Sharing, and the "I Didn't See You" Defense
The "I didn't see you" defense does not protect drivers from liability — drivers have a legal duty to see cyclists and avoid hitting them, regardless of where you were riding.
Drivers hit cyclists and then claim they didn't see them. It's a documented pattern in personal injury law. But you have a legal right to be on the road, you have a right to use a bike lane if one is available, and drivers have a legal duty to see you and not hit you.
If you were in a bike lane, that matters. Take photos of the bike lane or lack thereof. If there was a bike lane and the car entered it and hit you, that's clear-cut evidence. If there was no bike lane and you were in the traffic lane, that's also relevant. The key is that the driver had a duty to see you and avoid hitting you, regardless of where you were. Documenting where you were, what the road looked like, and what the driver's visibility situation was helps prove that.
When You Need a Lawyer
Contact a personal injury attorney if you're injured beyond minor scrapes or if a vehicle was involved — most work on contingency and offer free consultations.
An attorney investigates the accident more thoroughly than you can, pulls traffic footage, subpoenas medical records, determines what your case is worth, and negotiates with insurance companies. They understand state-specific rules about comparative negligence, helmet use, and bike lane laws that affect your claim.
Right After, and in the Days Ahead
In the first few days, follow up with your doctor's appointments, file the insurance claim if another vehicle was involved, and gather all the documentation — police report, medical records, repair estimates, photos, and witness information. Document any missed work with employer or medical records. Track your recovery timeline: how long before you could walk normally, how long before you could cycle again, how much medical treatment you needed. All of this determines how much your claim is worth.
And if you're shaken up by what happened, that's completely normal. Being hit by a car while you're on a bike is a violating experience. Your body has been through something. If you feel anxious about riding again, or if you have nightmares, or if you just need to take some time away from cycling before you feel ready, all of that is fine.
FAQ
Do I have to report a bicycle accident to the police?
If a vehicle hit you, call the police and file a report, especially if there's injury or property damage. A police report creates an official record and a report number you'll need for insurance claims. Even for bike-only accidents, documentation matters if injuries develop later.
Can I recover compensation if I wasn't wearing a helmet?
Your recovery depends on your state's rules. Some states treat helmet use as irrelevant to driver liability; others reduce recovery if you weren't helmeted. An attorney licensed in your state can explain how helmet use specifically affects your claim.
What if the driver left the scene?
Report the hit-and-run to police immediately — it's a separate crime in every state. File a report even if you didn't get the driver's information. Your own auto insurance's uninsured motorist coverage may apply if you have it.
How much time do I have to file a claim?
Report to police immediately if a vehicle was involved. For insurance claims, contact the driver's insurance within a few days. Statutes of limitations for lawsuits vary by state, typically 2–3 years. Waiting longer weakens your case because memories fade and evidence gets lost.
When should I talk to a lawyer?
If you're injured in any way beyond minor scrapes, or if a vehicle was involved, consult with a personal injury attorney. Most work on contingency — you pay nothing upfront. Free initial consultations are standard and help you understand whether you need representation.
