After a car accident, exchange each driver's full name, address, phone number, driver's license number, and vehicle registration, along with the insurance company name and policy number for every vehicle involved. Record the make, model, color, and license plate of each car, and note the owner if the owner is not the driver. In many states, part of this exchange is a legal duty, not a courtesy, and leaving without it can bring traffic or criminal penalties. Keep the conversation to facts. Share what the law requires, collect the same from the other driver, and avoid discussing fault, apologizing, or guessing about injuries. Photos of documents, the scene, and witness contact details make the record harder to dispute later.
The details matter because most crashes never look serious at the scene. NHTSA's overview of 2024 crash data estimates about 6.18 million police-reported crashes that year, and roughly 4.47 million of them involved property damage only. Injuries that surface days later still depend on the information gathered in those first minutes.
A missing policy number or a misspelled name can delay a claim for weeks. Getting the exchange right is one of the simplest ways to protect your claim, and it gives a car accident lawyer solid facts to work with if the case is later contested.
What Information Should Drivers Exchange at the Scene?
Start with the people. From every driver involved, collect:
- Full legal name, home address, and a working phone number
- Driver's license number and the state that issued it
- Vehicle registration number and the name of the registered owner
- Insurance company name, policy number, and the policy's effective dates
State laws set the minimum. New York's leaving-the-scene statute, for example, requires a driver to stop, show a license and insurance identification card, and give a name, street address, insurance carrier, policy number with effective dates, and license number. Other states require less at the scene, sometimes only a name, address, registration number, and license on request. Collecting the full set protects you either way.
The duty does not disappear when no one is around. If you hit a parked car or damage property and the owner is not present, New York requires the driver to report the incident to the nearest police station as soon as physically able. Get the names and phone numbers of passengers in the other vehicle too. They are witnesses, and they may have injury claims of their own.
Take a photo of the other driver's license and insurance card rather than copying them by hand. If the other driver was working for a rideshare company, ask whether the app was on and whether a passenger was aboard. New York requires rideshare drivers to disclose that status and produce proof of the required coverage, because it determines which policy applies. These are among the first steps after a car accident that shape everything that follows.
Which Insurance and Vehicle Details Should You Record?
Insurance details decide who pays, so record them exactly as they appear on the card. Note the insurer's claims phone number if it is listed, and confirm the policyholder's name. The policyholder is often a parent, spouse, or employer rather than the driver.
For each vehicle, write down:
- Year, make, model, and color
- License plate number and issuing state
- Visible damage and where it sits on the vehicle
- Company name and markings on any commercial vehicle
- Rental company and agreement number if the car is a rental
Commercial vehicles deserve extra attention. Trucks covered by federal motor carrier safety rules must display the operating carrier's name and a USDOT number on both sides, and that number identifies the company responsible for the truck. For delivery vans, work trucks, and company cars, note the business name and ask whether the driver was on the job, since an employer's commercial policy may be in play.
What Information Should You Avoid Sharing After a Crash?
The exchange should cover identity and insurance, nothing more. Avoid:
- Admitting or discussing fault. Even a reflexive "I'm so sorry" can be quoted later as an admission.
- Guessing about injuries. Saying "I'm fine" before a medical evaluation can undercut a claim if pain appears the next day.
- Your Social Security number or financial details. Crash exchange laws call for identity and insurance information, not these.
- Your coverage limits. The other driver needs your insurer and policy number, not how much coverage you carry.
- Signing anything. Do not sign a release, a payment agreement, or a written statement at the scene.
- Posting about the crash. Photos and comments on social media can be pulled into a claim and read out of context.
Fault is decided later, using physical evidence, reports, and statements. Loose comments at the scene tend to resurface when fault is disputed after a crash, and they are hard to walk back. Be polite, stick to facts, and let the evidence speak.
Photos, Witnesses, and the Police Report Fill the Gaps
The information exchange tells you who was involved. Photos and witnesses help show what happened. Use your phone to capture the other driver's documents, both vehicles from several angles, license plates, skid marks, traffic signals, and road conditions. Knowing which photos to take after a crash before you need them saves time when you are shaken and distracted.
Witnesses are easy to lose. Bystanders often leave before police arrive, so ask for a name and phone number right away. A short voice memo recording what a witness saw, made with permission, can help if memories fade.
If police respond, write down each officer's name, badge number, and agency, along with the report number. The report will usually list the drivers, vehicles, and insurers, which provides a backup if anything you collected turns out to be wrong.
Documenting Information Safely When Someone Is Injured
Safety comes before paperwork. If anyone is hurt, call 911 first. Many states pair the information duty with a duty to help. Florida's statute, for instance, requires drivers to give reasonable assistance to anyone injured, including arranging transport for medical treatment when it is clearly needed.
If you are too hurt to handle the exchange, let officers or a passenger gather the details, and request the police report afterward. Florida's law also covers the situation where no one at the scene can receive the information and no officer is present: the driver must report the crash to the nearest police authority.
Report the crash to your own insurer promptly as well. Auto policies generally require prompt notice, and a late report gives the insurer a reason to question the claim.
Get checked by a doctor even if you feel fine. Adrenaline can mask symptoms, and a prompt medical record links your injuries to the crash. Once you have the other driver's information and your medical records, you have what you need to start a claim. There are good reasons to contact a lawyer after a car accident before giving a recorded statement to the other driver's insurer.
Frequently Asked Questions
What if the other driver refuses to exchange information?
Do not argue or try to stop them from leaving. Photograph their license plate, vehicle, and face if you can do so safely, and call the police. Refusing to exchange the required information, or leaving the scene, violates state law in many situations and can become a criminal matter when someone is injured. Write down everything you remember, including the direction the driver went. Your own uninsured motorist coverage may apply if the driver is never identified, though some policies and states set conditions for hit-and-run claims.
Should you exchange information before the police arrive?
Yes, if it is safe. Move to a safe spot if the vehicles can be driven and your state allows it, then begin the exchange. Waiting risks losing the other driver, witnesses, or both. If police are on the way, stay at the scene until they arrive and give them the same information. In some states, officers at the scene are required to help drivers complete the exchange. Keep the conversation to documents and facts while you wait.
What if the other driver does not have insurance?
Collect everything else anyway: name, address, license number, plate, and registration. Tell the responding officer and your own insurer. Your uninsured motorist coverage may pay for your injuries. The at-fault driver also remains personally responsible for the damage. An uninsured driver may try to settle privately at the scene, so avoid informal cash deals, which rarely cover injuries that appear later.
Do you have to call the police after a minor accident?
It depends on the state and the damage. Many states require drivers to notify police when a crash causes injury, death, or damage above a set dollar amount. Florida, for example, requires contacting law enforcement for any crash involving injury or at least $500 in apparent damage. Even when a report is not required, calling police creates an independent record of who was involved, which helps when the other driver's story changes later.
