What to Do After a Car Accident: A Step-by-Step Guide

A car accident can happen in seconds and leave you shaken, disoriented, and unsure what to do next. Most people have never been in one before, and in the moment, it's easy to make mistakes that complicate your insurance claim, your medical situation, or even your legal standing.

This guide walks through exactly what to do — from the first seconds after impact through the days that follow.

Immediately After Impact: Stay Calm and Stay Safe

Step 1: Don't drive away.

Leaving the scene of an accident — even a minor one — is a crime in every state. Pull over to the side of the road if you can move your vehicle. If your car is disabled, turn on your hazard lights.

Step 2: Check for injuries.

Before anything else, check yourself and your passengers for injuries. Don't move anyone who might have a neck or spinal injury unless they're in immediate danger (fire, traffic).

Step 3: Move to safety if possible.

If the vehicles can be moved and it's safe to do so, pull them off the road to prevent further accidents. If you're on a highway, get behind a guard rail if possible — don't stand next to the road.

Step 4: Call 911.

Call 911 for any accident involving:

• Injuries
• Significant property damage
• A hit-and-run
• A driver who seems impaired
• Any dispute about what happened

For minor fender-benders with no injuries and cooperative parties, a police report may not be legally required, but it's still often recommended — it creates an official record.

At the Scene: What to Document

This step is where many people fail. Proper documentation protects you in ways that become obvious weeks later when an insurance adjuster asks for details you can no longer remember.

Exchange Information With the Other Driver(s)

Collect:

• Full name and contact information
• Driver's license number and state
• License plate number
• Vehicle make, model, year, and color
• Insurance company name and policy number
• Phone number of anyone in their vehicle

Get Witness Information

If bystanders saw the accident, ask for their names and phone numbers. Independent witnesses carry significant weight with insurance adjusters and in court.

Document the Scene

Use your phone to photograph:

• All vehicles involved — from multiple angles, including damage, overall position, and license plates
• The surrounding area — road conditions, traffic signs, lane markings, skid marks
• Any visible injuries — bruises, cuts, anything you can document
• The weather and lighting conditions
• The position of vehicles before they're moved (if possible, photograph before moving)

Take more photos than you think you need. Storage is free.

Talk to the Police — Carefully

Give a factual account of what happened. Don't speculate, and don't admit fault — even if you think you might be partially responsible. You don't have all the facts yet. Fault determination involves physical evidence, witness accounts, traffic laws, and sometimes accident reconstruction. Let investigators do their job.

What you can say: "I was traveling north on Main Street when the collision occurred." What to avoid: "I think I might have been going a little fast" or "I didn't see them coming."

Get the responding officer's name and badge number, and ask how to obtain the official accident report. Most jurisdictions post accident reports online or at the police station within a few days.

What Not to Do at the Scene

Don't admit fault. Even a casual "I'm so sorry" can be used against you in a claim. Express concern for people's wellbeing without admitting legal liability.

Don't negotiate a cash settlement. The other driver may offer to pay for damages in cash to avoid an insurance claim. This is almost always a bad idea. Hidden damage, latent injuries, and the loss of any legal recourse if the other driver backs out aren't worth the convenience.

Don't sign anything. Don't sign any documents at the scene that aren't official police or DMV forms.

Don't move seriously injured people. Unless there's an immediate threat (fire), let emergency responders handle anyone with possible neck or spinal injuries.

Seeking Medical Attention

Even if you feel fine after an accident, get checked out. Adrenaline masks pain. Whiplash, soft tissue injuries, and even traumatic brain injuries can present hours or days after the incident.

Go to an emergency room or urgent care facility and tell them you were in an auto accident. This creates a medical record linking your injuries to the collision, which is essential if your injuries require ongoing treatment or if a claim needs to be made.

Delaying medical care has two consequences: it may worsen your condition, and it gives insurers grounds to argue that your injuries weren't caused by the accident.

Reporting the Accident to Your Insurance Company

Contact your insurer as soon as practical — the same day if possible, or the next morning.

Most insurers have 24/7 claims lines and apps. When you call, have:

• The accident date, time, and location
• The police report number (if a report was filed)
• The other driver's insurance information
• Your photos and documentation

Do you have to report an accident to your own insurer even if the other driver was at fault?

Generally, yes. Most insurance policies require you to promptly report any accident involving your vehicle, regardless of fault. Not reporting can give your insurer grounds to deny coverage if a complication arises later.

Reporting to your insurer doesn't mean they'll raise your rates — that depends on fault, your history, and your state's regulations.

When the Other Driver Was At Fault

If the other driver caused the accident, you have two paths:

File a claim with their insurer (third-party claim): You contact their liability insurer directly. They investigate and, if their driver is at fault, pay for your vehicle repairs and medical bills up to their policy limits.

File with your own insurer first: If the other driver is uncooperative, uninsured, or their insurer is dragging their feet, you can file with your own insurer under your collision coverage. Your insurer will then pursue the other driver's insurer for reimbursement (a process called subrogation).

If you have uninsured/underinsured motorist coverage and the at-fault driver has no insurance or insufficient coverage, your policy will cover your losses up to your policy limits.

In the Days Following

Keep records of everything:

• All medical appointments and treatments
• Days missed from work
• Transportation costs to medical appointments
• Rental car costs
• Any out-of-pocket expenses directly related to the accident

These are all potentially compensable losses.

Get repair estimates: Your insurer will likely send an adjuster or direct you to an approved repair shop. You're generally entitled to multiple estimates, and in most states, you can use the repair shop of your choice.

Know your rights: If your vehicle is declared a total loss (repair cost exceeds the car's value), the insurer will offer you the vehicle's actual cash value. You can dispute this amount if you believe your car was worth more — document your car's condition and features, and research comparable vehicles in your market.

A Quick Reference Checklist

At the scene:

• Move to safety, turn on hazards
• Check for injuries, call 911
• Exchange information with other driver(s)
• Get witness contact information
• Photograph everything — vehicles, scene, injuries
• Speak with police — factual only, no admissions of fault
• Get officer's name and badge number

After the scene:

• Seek medical attention (even if you feel fine)
• Call your insurance company
• Obtain the official accident report
• Track all expenses and lost wages
• Keep copies of all correspondence with insurers

The accident itself is out of your control. What happens afterward isn't. Thorough documentation and prompt action protect you far better than improvising in the moment.
