The short version
- Safety comes first: check for injuries and get out of traffic when you safely can.
- Exchange insurance and contact details, take plenty of photos, and note any witnesses.
- Stick to facts at the scene and let insurers sort out who was at fault.
A fender bender usually happens in a second. A slow roll into the car ahead at a stoplight, a misjudged turn in a parking lot, a lane change that was a little too close. Nobody is badly hurt, but your heart is pounding and it is hard to think straight.
That first hour matters more than people expect. What you do at the scene can shape how smoothly the claim goes later and, more importantly, keeps everyone safe while you sort things out. This guide walks through it in order. Laws and reporting rules differ by state, so treat this as general guidance and follow any instructions from police at the scene.
The first few minutes: safety before paperwork
Stop the car. Driving away from a crash without stopping and sharing your information is against the law in every state, even when the damage looks small. Turn on your hazard lights and take a breath.
Check yourself and your passengers, then the people in the other vehicle. If anyone is hurt, complains of pain, seems confused, or if you are simply not sure, call 911. Injuries from low-speed crashes, especially to the neck and back, sometimes do not show up right away.
If no one is hurt and the cars can be driven, move them out of the travel lanes to a shoulder, side street or parking lot. Many states actually require drivers in minor, injury-free crashes to clear the roadway when it is safe to do so. If a car cannot be moved, or moving it would be dangerous, stay out of traffic, keep your hazards on and, if you carry them, set out flares or reflective triangles. Keep an eye on passing cars whenever you are standing outside your vehicle.
Deciding whether to call the police
Rules for reporting a crash to police vary by state. In general, it makes sense to call when someone is injured, when damage looks significant, when a driver seems impaired, when the other driver will not share information, or when the other driver leaves. Many states require a report when damage passes a certain dollar amount, and that amount differs from state to state.
Even when a report is not required, a police report can help your claim, because it records the time, place, parties and the officer's observations. In some places, police may not come out for a minor crash with no injuries. If that happens, ask how to file a report yourself, and write down the name of the person you spoke with.
Some states also require you to file your own crash report with the state motor vehicle agency within a set number of days if damage or injuries pass a threshold. Your insurer or local police can tell you whether that applies.
What to exchange with the other driver
Once everyone is safe, trade information calmly. You will want:
- Full name and phone number of each driver.
- Insurance company name and policy number.
- Driver's license number and issuing state.
- License plate number and state.
- Make, model and color of each vehicle.
- Name and contact information of the vehicle owner, if different from the driver.
The easiest way is often to photograph the other driver's license and insurance card, with their permission, and let them do the same with yours. If the other driver refuses to share details, do not argue. Note their plate number and call the police.
Photos and notes that help later
Your phone is the most useful tool you have after a crash. Take more photos than you think you need:
- Wide shots showing both cars and their positions, if they have not been moved.
- Close-ups of the damage on every vehicle, including small scrapes.
- License plates of all vehicles involved.
- Street signs, traffic lights, lane markings and landmarks.
- Road and weather conditions, such as wet pavement or low sun glare.
Then jot down notes while the details are fresh: the time, the location, the direction each car was traveling and what happened in your own words. If anyone saw the crash, ask for their name and phone number. Witnesses tend to leave quickly, so ask early.
What to say, and what to leave for later
It is natural to want to apologize or explain. Be polite and human, but stick to facts. Announcing at the scene that the crash was all your fault can complicate things later, especially when you may not have the full picture. Perhaps the other driver was speeding, or ran a light you did not see.
Fault is decided by insurers and, sometimes, the police or courts, based on the evidence and your state's laws. Let that process work. Likewise, think twice before agreeing to settle privately in cash before you understand the full damage. A scraped bumper can hide broken brackets and sensors that cost far more than they look.
Avoid signing anything at the scene other than paperwork from a police officer.
The calm checklist
Save this list on your phone so you have it when you need it:
- Stop, turn on hazard lights and check for injuries.
- Call 911 if anyone is hurt or if you are unsure.
- Move to a safe spot if the cars can be driven and it is safe.
- Call the police if your state requires it or if something feels wrong.
- Exchange names, phone numbers, insurance and license details.
- Photograph the vehicles, plates, damage and scene.
- Get names and numbers of witnesses.
- Write down what happened while it is fresh.
- Stick to facts and avoid debating fault.
- Get the police report number, if there is one.
- Notify your insurer as soon as you reasonably can.
After the hour is over
Most policies require prompt notice of an accident, even one you think is minor or not your fault. Calling your insurer early gets a claim number on file, and they can explain your options for repairs, rental cars and any claim from the other driver. If you feel sore later that day or the next morning, get checked by a doctor and keep the paperwork.
A fender bender is also a good nudge to look at your coverage while things are calm. Check whether you have collision coverage, rental reimbursement and enough liability protection for your situation. If you want to compare, AutoAssures can pass one request to up to four licensed partners in your state, and you can review their options on your own schedule.
