Your hands are shaking. Maybe someone is crying. There's broken glass or a crumpled bumper in front of you. Knowing what to do after a car accident step by step - before it ever happens - is one of the most practical things you can do as a driver.
Most people freeze or panic and forget to do the things that matter most. This guide walks you through every step from the moment of impact to following up with your insurer days later. Bookmark it, share it with your teenage driver, and keep it in the back of your mind every time you get behind the wheel.
Your First 60 Seconds
The first thing to do is take a breath. Seriously. Adrenaline is rushing through your body and your judgment is impaired by stress. A few deep breaths before you do anything will help you think clearly. This is not a small thing - panicked people make mistakes that hurt their insurance claims and sometimes put them in more danger.
Turn on your hazard lights immediately. This one action warns other drivers and prevents a second accident. If your car is in a lane of traffic and it is safe to move, get it to the shoulder or a nearby parking lot. If you cannot move the car safely, stay inside with your seatbelt on until help arrives. Standing on a highway next to a disabled car is one of the most dangerous places you can be.
Check for Injuries Before Anything Else
Check yourself first, then any passengers. Adrenaline is a powerful numbing agent - you might not feel an injury right away that becomes obvious 30 minutes later. Ask everyone in your car how they feel. Pay attention to neck pain, headaches, or dizziness, which can signal whiplash or a concussion that does not show up immediately.
Check on the other driver and any passengers in their vehicle too. You do not have to be friends with someone who may have just hit you - basic human decency goes a long way and keeps the situation calm.
Call 911 if anyone is injured, if vehicles are blocking traffic and cannot be moved, if you suspect the other driver is intoxicated, or if the other driver is becoming hostile. In many states, you are also legally required to call police whenever an accident causes injury or property damage above a certain threshold - often $1,000 to $1,500.
What to Collect at the Scene
This is where most people underperform. They exchange numbers with the other driver and leave - and then spend weeks wishing they had gotten more information. Here is what you actually need.
From the other driver: full name, phone number, home address, driver's license number, license plate number, insurance company name, and policy number. Take a photo of their license and insurance card rather than copying it by hand - it is faster and more accurate. If they refuse to let you photograph it, write everything down manually.
If there are witnesses, ask for their names and phone numbers. Witnesses are gold if the other driver changes their story later. Most people are willing to help if you simply walk up and politely ask if they saw what happened.
Take photos - a lot of them. Get the damage on both cars from multiple angles, the overall scene showing where the cars came to rest, any skid marks, traffic signs, and traffic lights. If there is visible damage to property like a fence or guardrail, photograph that too. Take a wide shot that shows the intersection or stretch of road where it happened. You cannot take too many photos.
What Not to Say (This Matters More Than You Think)
Do not apologize. Even "I'm so sorry, are you okay?" can be interpreted as an admission of fault. Stay calm and check on the other person without using language that implies you caused the accident. This feels counterintuitive if you are a polite person, but it is genuinely important.
Do not say "I didn't see you" or "I was distracted" or "I was going a little fast." These statements will be used against you. Stick to factual, neutral language. "Are you hurt? I'm going to call 911" is fine. "It's my fault" or "I should have braked sooner" is not.
Do not discuss fault with the other driver at all. That determination belongs to the insurance companies and, if necessary, the courts. Fault in accidents is often more complex than it appears on the surface - there may be factors like road conditions, mechanical failure, or the other driver's prior actions that you are not aware of in the moment.
Calling Your Insurance Company
Call your insurer as soon as you are safely away from the scene - ideally the same day, definitely within 24 hours. Most policies require prompt notification. Waiting too long can give the insurance company a reason to complicate or reduce your claim.
Call even if the accident was not your fault. Your insurance company needs to know what happened so they can protect your interests, especially if the other driver's insurer tries to lowball you or dispute liability. You are paying for their representation - use it.
Have your policy number ready. The claims representative will ask for the date, time, and location of the accident, a description of what happened, the other driver's information, and whether anyone was injured. Answer factually. If you are unsure about something, say so rather than guessing.
Once you file the claim, you will be assigned an adjuster who handles your case. Our full breakdown of what actually happens after you file a car insurance claim walks you through every step of that process in detail.
After You Leave the Scene
Go see a doctor even if you feel fine. This is not about being overly cautious - it is about documentation. Injuries from car accidents, especially soft tissue injuries like whiplash, can take 24 to 72 hours to fully manifest. If you show up with neck pain three days later and have no medical record from after the accident, the other driver's insurer will argue the injury is not related.
Get the police report number if police responded. You can usually request a copy online within a few days. This report is one of the most important documents in your claim.
Write down everything you remember while it is fresh. The exact sequence of events, what the weather was like, whether any traffic signals were working, how fast you were going, what you saw before impact. Your memory of details will fade within days.
The Days That Follow
Stay in contact with your insurance adjuster. Respond to their calls and emails promptly. The faster you cooperate, the faster your claim moves. Ask for updates if you have not heard anything in three to four days.
Keep records of everything - repair estimates, medical bills, rental car expenses, and any time you miss work due to injuries. Depending on your coverage and who was at fault, some or all of these costs may be reimbursable.
Before you decide whether to file a claim at all, you might want to read our article on whether filing a car insurance claim raises your rates. For minor accidents with no injuries and damage below your deductible, sometimes paying out of pocket is the smarter financial move.
No accident is fun, but the drivers who come out of them with the least damage - financially and emotionally - are the ones who knew what to do before it happened. Keep your insurance card in your car, save your insurer's claims number in your phone, and take a few minutes to review your current coverage so you are never caught off guard.
