Quick Action Checklist (What to Do at the Scene)
- Ensure safety: move to a safe location if the vehicles are drivable and it’s safe to do so.
- Call 911 if anyone is injured or if there is substantial property damage.
- Exchange contact, insurance, and vehicle information with the other driver(s).
- Take photos and videos of the scene (vehicle positions, damage, skid marks, traffic signs, lighting).
- Get names and phone numbers of witnesses.
- Avoid admitting fault or making statements like “I’m sorry” that could be construed as accepting blame.
- Seek medical attention immediately for any injury or symptom — even if you think you are “okay.”
- Notify your insurer according to your policy requirements.
Immediate Medical & Evidence Steps
- Get medical care: document every visit, diagnosis, treatment, and referral.
- Keep contemporaneous notes of symptoms, pain, medication, and how injuries affect daily life.
- Preserve digital evidence: dashcam files, phone photos, messages, or app data (rideshare), and vehicle telematics if available.
- Request the police report number and instructions for obtaining the full report.
Reporting, Police, and Insurance: Who to Call and When
- If injury or major damage: call 911 and request police at the scene.
- For minor crashes, many states still require driver exchange and/or crash report filing within a set time.
- Notify your insurance company as required by your policy — many policies require prompt notice and have specific deadlines.
Legal Systems That Change How Fault and Recovery Work
Pure Comparative Negligence
- Plaintiffs can recover damages even if they are mostly at fault; recovery is reduced by their percentage of fault. Examples include California, Florida, and New York.
Modified Comparative Negligence
- Plaintiffs can recover only if their fault is below a threshold (commonly 50% or 51%). If the plaintiff’s share exceeds the threshold, recovery is barred.
Contributory Negligence
- If the plaintiff is at all at fault (even 1%), they are barred from recovery. Only a few states retain this system.
No-Fault Insurance / Personal Injury Protection (PIP)
- In no-fault states, each party typically claims first-party benefits (medical, wage loss) from their own insurer regardless of fault. Suits for pain and suffering may be limited unless injuries meet a statutory threshold.

Working with Insurers & Adjuster Tactics
- Consider consulting an attorney before giving recorded statements for serious injuries.
- Do not sign unnecessary medical releases.
- Keep meticulous records of all communications.
- Document medical causation clearly to avoid undervaluation.
When to Hire an Attorney & What They Do

Statute of Limitations (Time to Sue)

- Special rules apply for suits against government entities.
- Missing deadlines typically destroys the right to sue.
