Washington Hit-and-Run Crashes: What to Do and How a Plate Lookup Helps

Under Washington law (RCW 46.52.020 et seq.), any driver involved in an accident causing injury, death, or property damage must immediately stop, provide their name, address, and vehicle registration, and render reasonable assistance. Leaving the scene carries severe penalties:

• Hit-and-run involving property damage only: Misdemeanor — up to 90 days in jail and/or $1,000 fine
• Hit-and-run involving injury: Class C felony — up to 5 years imprisonment and/or $10,000 fine
• Hit-and-run involving serious injury: Class B felony — up to 10 years imprisonment and/or $20,000 fine
• Hit-and-run involving death: Class B felony — up to 10 years imprisonment and/or $20,000 fine (Class A if vehicular homicide)
• License revocation mandatory upon conviction for any hit-and-run in Washington
• Seattle and Tacoma rank among the Pacific Northwest cities with the highest hit-and-run rates — a licensed PI plate lookup is a critical tool for victim identification

If you were the victim of a hit-and-run in Washington, here is your immediate action plan:

1. Call 911 immediately. Washington State Patrol handles crashes on state and federal highways; local police handle city streets; county sheriffs handle rural county roads.
2. Note everything about the fleeing vehicle — full or partial plate number, color, make, model, damage, and direction of travel.
3. Do not follow the fleeing vehicle.
4. File an insurance claim — Washington requires minimum liability insurance on all registered vehicles.
5. Contact a licensed PI to run the plate for registered owner identification — this is a DPPA-permissible use for legal proceedings and insurance claims.
