What to Do After a Car Accident: 12 Steps That Protect Your Claim

Most of the value of a car accident claim is determined in the first two weeks — usually by people who have no idea that is what is happening. The evidence that decides liability is at the scene and disappears within hours. The medical record that establishes causation is created on day one or not at all.

What follows is the sequence in the order it actually matters.

Quick answer: Call 911, photograph everything before vehicles are moved, get medical care the same day, notify your own insurer, and say nothing about fault or injuries to the other side’s insurer.

At the Scene

1. Check for injuries and get to safety

Injuries first. If the vehicles are drivable and blocking traffic, move them to the shoulder — but photograph their final resting positions first if you safely can, because point of impact and vehicle orientation are what reconstruction experts work from.

2. Call 911

Always, even for what looks minor. You get three things from one call: emergency medical response, an independent record of the incident, and a preliminary fault assessment by a neutral party.

Most states require a report where anyone is injured or property damage exceeds a threshold. If police decline to respond to a minor collision, file a report at the station or through your state’s online system, and get the report number.

3. Photograph everything — before anything moves

This is the most valuable ten minutes of the entire claim. Capture:

• Wide shots showing both vehicles, their positions and the roadway
• Close-ups of all damage on every vehicle, including the other driver’s
• The other vehicle’s license plate, and any commercial or rideshare markings
• Skid marks, debris fields, fluid trails
• Traffic controls — signals, signs, lane markings, obstructions
• Road and weather conditions, and lighting
• Visible injuries on yourself and passengers
• The other driver’s license, insurance card and registration
• A short video panning the whole scene while describing what you see

Photograph even trivial-looking damage. Low property damage is the foundation of the “minor impact” defense, and modern bumpers absorb substantial energy while showing little deformation. These same photographs also matter for the vehicle claim itself — see our guide to total loss, diminished value and loss of use for how the vehicle side is valued and the release trap to avoid there.

4. Exchange information — and nothing more

Get name, address, phone, insurer and policy number, driver’s license number, plate and vehicle details. If the driver was working — delivery, rideshare, commercial — get the employer’s name, and any USDOT number on a truck. A commercial defendant usually means far more insurance coverage.

Say nothing about fault. Not “I didn’t see you,” not “I’m so sorry,” not a speed estimate. These become admissions.

5. Find witnesses before they leave

Independent witnesses are decisive in disputed-fault cases and they disappear within minutes. Get names and phone numbers. Note nearby businesses, homes and intersections with cameras — footage often overwrites within days, so its existence must be identified early.

6. Say nothing to the other driver about your condition

“I’m fine” is the sentence that costs the most money in this entire process. You do not yet know whether you are fine. Say you are getting checked out.

The First 48 Hours

7. Get medical care the same day

Even if symptoms are mild. Concussions, internal bleeding, and soft tissue injuries frequently present hours to days later, and the medical record created now is what connects your later diagnosis to this crash.

Describe every symptom, including things that feel unrelated — headache, dizziness, nausea, numbness, tingling, sleep disruption, difficulty concentrating. Symptoms absent from the initial record are the ones later characterized as unrelated.

In no-fault states, watch the clock. Florida, for example, requires initial treatment within 14 days to access personal injury protection benefits. Other no-fault states impose their own notice requirements.

8. Notify your own insurer

Required by essentially every policy, and failing to do so can jeopardize your own collision, medical payments and uninsured motorist coverage — even in a crash that was entirely the other driver’s fault. Report the facts. You are not required to speculate about fault.

9. Start a claim file

One folder, physical or digital, holding: the police report number, photographs, all medical records and bills, receipts for every out-of-pocket expense (prescriptions, mileage to appointments, medical devices), wage-loss documentation, and a log of every insurance contact with dates and names.

The First Two Weeks

10. Follow the treatment plan exactly

Attend every appointment, complete the referrals, finish the physical therapy. Gaps in treatment are the single most effective tool insurers have for devaluing a claim — a three-week break is routinely presented as proof you had recovered.

11. Handle the other insurer carefully

Their adjuster will call within days, friendly and efficient. You owe them nothing:

• No recorded statement. You are not required to give one to a third-party insurer.
• No blanket medical authorization. It is a search for pre-existing conditions.
• No discussion of injuries while you are still being evaluated.
• No early settlement. The offer is made precisely because the claim’s value is not yet known.

For the specific tactics to expect and how to answer each one, see our guide to dealing with insurance adjusters.

12. Get an evaluation before you agree to anything

Consultations are typically free, so an assessment costs nothing. Get one when: liability is disputed; you were hospitalized or had surgery; a commercial, government or rideshare vehicle was involved; symptoms persist beyond a few weeks; or the offer is at or below your medical bills.

The Mistakes That Do the Most Damage

Mistake	Consequence
No police report	The other driver’s account becomes unchallenged
Delaying medical care	Causation attacked directly — the most common denial
Saying “I’m fine”	Quoted back throughout the claim
Admitting fault or apologizing	Treated as an admission
Gaps in treatment	Read as recovery; devalues everything after the gap
Recorded statement to the other insurer	Permanent, quotable answers given before you knew the facts
Signing a blanket medical release	Opens your entire history to a causation defense
Posting on social media	Contradicts claimed limitations
Accepting an early offer	Closes the claim permanently, including future surgery
Missing the filing deadline	Ends the claim regardless of merit

On that last row: every state sets a statute of limitations, commonly two or three years but as short as one year in a few states — and claims involving government vehicles often require notice within six months. See our state-by-state filing deadline reference.
