Quick Summary: 5 Essential Steps to Report an Accident Immediately

For instant action after a crash, follow this checklist. In 2022, 11.4% of injury crashes were hit-and-runs (Pew Research), underscoring the need for quick, accurate reporting.

1. Ensure Safety: Move vehicles if safe; turn on hazards; check for injuries.
2. Call 911 if Needed: Injuries, death, traffic blockage, DUI suspicion, or state-specific damage thresholds (e.g., $1,000 in MI/WA).
3. Exchange Info: Names, licenses, insurance, vehicle details, photos.
4. Document Scene: Photos, witnesses, diagrams.
5. Report Promptly: Police within 24-48 hours; insurance/DMV per state deadlines (e.g., 24 hours MI, 30 days CA).

Key Takeaways Box:

• Call 911 for injuries, blockage, or $1,000+ damage in threshold states.
• Report within 24-48 hours to avoid claim denials.
• Always get a police report for insurance leverage--used in 90%+ of claims.

Key Takeaways

• Prioritize safety: Exit vehicle, check injuries before anything else.
• Call 911 for serious injuries, fatalities, blockage, DUI, or high damage.
• Exchange full info: license, registration, insurance, photos.
• Report minor crashes without police if no injuries/damage over thresholds, but document everything.
• State deadlines vary: 24 hours (MI), 4 days (WA), 10 days (most); miss them and face fines/license suspension.
• Hit-and-runs: Gather evidence like partial plates; claim UM insurance.
• Autonomous/EV crashes: Report data logs; liability may shift to manufacturers.
• Use apps like Corfix for digital reports; avoid admitting fault.
• Fleet drivers: Notify employer immediately per policy.
• Common pitfalls: Delaying reports, inconsistent statements--insurers deny 20%+ for these.

What to Do Immediately After a Car Crash (First 15 Minutes)

Safety first--adrenaline can mask injuries. Follow this step-by-step checklist:

1. Stay Calm & Safe: Turn on hazard lights; move vehicles off road if possible and safe.
2. Check for Injuries: Ask everyone involved; call 911 if anyone needs aid.
3. Secure Scene: Place triangles/reflectors; warn other drivers.
4. Document: Photos of damage, positions, skid marks, road conditions.
5. Do Not Admit Fault: Say little beyond basics.

Stats: If blockage or DUI suspected, call 911--blocks cause 20% secondary crashes. Mini Case: Rear-end collision--hidden frame damage emerges days later; immediate photos proved liability.

When to Call 911 After a Vehicle Collision

Call immediately for:

• Any injuries or fatalities.
• Traffic blockage.
• DUI signs (slurred speech, alcohol smell).
• State thresholds: $1,000+ damage (MI, WA); hazardous materials.

Variations: MI mandates for $1,000+ property damage; general rule is "if unsafe." Delaying risks lives and liability.

1. Call Non-Emergency: If no 911 triggers, use local police line.
2. Provide Details: Location, vehicles, injuries, witnesses.
3. Officer Arrives: Give statements; get report number.
4. File if Needed: Some states require at station for minors.
5. Follow Up: Lookup number online.
