The minutes after a car crash are chaotic — you're shaken, traffic is piling up, and the other driver may already be spinning a story. What you do in the first hour, and the first week, can determine whether your injury claim succeeds or collapses. Insurance companies start building their defense the moment a crash is reported; this checklist makes sure you're building your case just as fast.
Print it, save it, or just remember the order: safety, evidence, silence, medical care, lawyer.
At the scene: the first 30 minutes
1. Check for injuries and call 911. Safety first, always. Even if the crash seems minor, call the police — a police report is the single most important document in most accident claims. In many states you're legally required to report crashes involving injuries or significant property damage.
2. Move to safety if you can. If the cars are drivable, move them out of traffic. Turn on hazard lights, set out warning triangles if you have them.
3. Document everything with your phone. Before anything gets moved or cleaned up, photograph: all vehicles from multiple angles, license plates, the road (skid marks, debris, traffic signals), weather and lighting conditions, and any visible injuries. Take more photos than you think you need — you can't go back for them later. If there are witnesses, ask for names and phone numbers; independent witnesses win disputed cases.
4. Exchange information — and nothing else. Get the other driver's name, phone number, insurance company and policy number, license plate, and driver's license number. Give them yours. That's it. Do not discuss who was at fault, apologize, or say "I'm fine." Apologies get quoted back at you in settlement negotiations, and "I'm fine" becomes Exhibit A when you discover an injury three days later.
5. Never admit fault at the scene. Even a polite "I'm so sorry" can be twisted into an admission of liability. Stick to facts with the other driver and the police: what happened, where, when. Let the investigators determine fault.
The first 24 hours
6. Get medical attention — even if you feel okay. Adrenaline masks injuries. Whiplash, concussions, and soft-tissue injuries often surface 24–72 hours after a crash. Seeing a doctor immediately creates a medical record linking your injuries to the accident. Gaps in treatment are the number one reason insurers deny or devalue claims — "if you were really hurt, why did you wait two weeks?"
7. Report the crash to your own insurer. Your policy requires prompt notification. Give the basic facts. You are not required to give a recorded statement to the other driver's insurance company — and you shouldn't, at least not before talking to a lawyer. Their adjuster's job is to minimize what they pay you.
8. Start a crash file. One folder (physical or digital) with everything: the police report number, photos, medical receipts, the tow truck receipt, rental car bills, and a daily log of your pain levels and missed work. This file becomes the backbone of your claim.
The first week
9. Follow your doctor's orders exactly. Missed appointments and ignored treatment plans don't just hurt your health — they hurt your case. Insurers argue that skipped treatment means you weren't really injured.
10. Don't sign anything from the other insurer. The at-fault driver's insurance company may call quickly with a settlement offer — sometimes within days, before you know the full extent of your injuries. Early offers are almost always lowball. Never sign a release or accept payment without understanding what your claim is actually worth. Once you sign, your case is over, even if you need surgery a month later.
11. Preserve evidence. Keep damaged clothing, don't repair your car until it's been photographed and appraised, and save all dashcam footage. If your car has an event data recorder ("black box"), your lawyer can help preserve that data before it's overwritten.
12. Watch what you post. Insurance investigators check social media. A photo of you at a birthday party three days after the crash becomes "proof" you weren't injured — even if you were in pain the whole time. Best practice: post nothing about the accident, your injuries, or your activities until the claim is resolved.
Know your own coverage: PIP, MedPay, and uninsured motorist
Before you ever need it, understand three coverages on your own policy that matter enormously after a crash. Personal Injury Protection (PIP) — mandatory in no-fault states — pays your medical bills and some lost wages regardless of who caused the crash. Medical Payments (MedPay) is optional coverage that pays medical bills for you and your passengers, also regardless of fault, and it's cheap to add. Uninsured/underinsured motorist (UM/UIM) coverage protects you when the at-fault driver has no insurance or too little — roughly 1 in 8 U.S. drivers is uninsured, so this coverage saves claims every day.
After a crash, these coverages determine how fast your bills get paid while the liability fight plays out. Tell your lawyer exactly what coverages you carry — the declarations page of your policy has the answers — because stacking available coverages is often the difference between a fully paid recovery and a shortfall.
When to call a lawyer
Not every fender-bender needs an attorney. But call a personal injury lawyer promptly — most offer free consultations — if any of these apply:
- Anyone was injured, even "just" whiplash or soreness
- Fault is disputed or the other driver is blaming you
- The other driver was uninsured or fled the scene
- The insurance company denied your claim or made a low offer
- The crash involved a commercial truck, rideshare, or government vehicle
- You're missing work or facing significant medical bills
Why promptly? Because evidence disappears, witnesses forget, and every state has a statute of limitations — typically 2–3 years, but as short as one year in some states. Miss it and you lose the right to sue entirely. Early legal advice is free; late legal advice can't undo a signed release or a blown deadline.
State rules also change the strategy. In no-fault states like Florida, New York, or Michigan, your own Personal Injury Protection covers initial medical bills regardless of fault. In contributory-negligence states like Virginia or Maryland, any fault on your part can destroy your claim — which makes what you say in the first hour especially critical.
Quick-reference checklist
- Call 911 and get a police report
- Photograph everything before vehicles move
- Exchange info; say nothing about fault
- Get witness names and numbers
- See a doctor within 24 hours
- Notify your own insurer
- Start a crash file with all documents

The bottom line
After a car accident, you have one job: protect your health and your claim, in that order. Document the scene, get medical care fast, keep your mouth shut about fault, and don't let an insurance company rush you into a cheap settlement. The checklist above takes an hour to follow and can be worth tens of thousands of dollars. Use it.
