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.

Common Injuries from Car Accidents


Evidence That Matters


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

  • Serious injuries, disputed liability, low settlement offers, or complex issues.
  • Attorneys investigate, collect evidence, calculate damages, negotiate, file suit, litigate, and appeal if needed.

Statute of Limitations (Time to Sue)

  • Varies by state (commonly 2–3 years for personal injury).
  • Special rules apply for suits against government entities.
  • Missing deadlines typically destroys the right to sue.

FAQs


Q: Do I have to speak with the other driver’s insurer?
A: Not required for serious injuries; cooperate with your own insurer as needed.

Q: How much is my case worth?
A: Depends on damages, liability, jurisdiction, and comparable verdicts.

Q: Will my insurance go up after a claim?
A: Possibly, depending on fault and your insurer’s rating system.
