Washington State Car Insurance Requirements & Average Cost (2026)
Washington requires 25/50/10 liability coverage, operates as a pure comparative fault state, and mandates written rejection for Personal Injury Protection (PIP).
Washington State combines dense urban commuter corridors in the Puget Sound with rural mountain passes. The Office of the Insurance Commissioner (OIC) enforces consumer protections, credit-scoring restrictions, and mandatory liability minimums.
| Policy Tier | Average Annual Rate | Average Monthly Rate | Suitability Profile |
|---|---|---|---|
| State Minimum (25/50/10 No PIP) | $680 | $57 | Legal compliance only; high personal asset exposure |
| Sensible Coverage (50/100/50 + PIP) | $1,120 | $93 | Recommended minimum for renters without financed loans |
| Full Coverage (100/300/100 + $500 Deductibles) | $1,940 | $162 | Financed cars, new vehicles, and family commuters |
| Seattle Metro Full Coverage Tier | $2,380 | $198 | Accounts for higher urban density and property theft risk |
Mandatory Minimum Limits (25/50/10)
Under Revised Code of Washington (RCW) 46.30.020, motorists must carry at least $25,000 bodily injury liability per person, $50,000 per accident, and $10,000 property damage liability. Washingtons $10,000 property damage limit is among the lowest in the U.S. and leaves drivers personally exposed to severe excess judgments.
Personal Injury Protection (PIP) Rules
RCW 48.22.085 mandates that insurance carriers offer Personal Injury Protection (PIP) on all motor vehicle liability policies. PIP pays medical bills and lost wages regardless of fault up to $10,000 (standard) or $35,000 (enhanced), unless the policyholder rejects it in writing.
