Uninsured Motorist Coverage — Washington
Free to compare
When Another Driver Has No Insurance
You're structuring coverage for two or more vehicles in Washington, and you've confirmed the state's minimum liability requirements: $25,000 per person for bodily injury, $50,000 per accident, and $10,000 for property damage. Those minimums protect others when you cause a crash. They do nothing when someone else hits you and carries no insurance at all.
Washington does not mandate uninsured motorist coverage. You can legally register and drive every vehicle in your household with only the state minimum liability limits. The structural reality: nearly one in five Washington drivers operates without any insurance, and your liability-only policy leaves you exposed when one of them causes a collision that injures you or damages your car.

Washington Uninsured Driver Rate
One in five drivers on Washington roads carries no insurance. When an uninsured driver causes a collision, your liability coverage does not respond — it only pays claims you cause, not claims filed against you.

What Uninsured Motorist Coverage Actually Pays
Uninsured motorist bodily injury coverage pays medical bills, lost wages, and pain-and-suffering damages when an at-fault driver has no insurance or insufficient limits to cover your injuries. The coverage applies per person and per accident, mirroring the structure of liability limits.
Uninsured motorist property damage coverage pays to repair or replace your vehicle when an at-fault uninsured driver damages it. Washington allows carriers to offer UMPD with or without a deductible; some policies require you to exhaust collision coverage first if you carry it, others let UMPD respond directly. The policy language controls which coverage applies first, and the order matters when your vehicle's value sits near the damage estimate.
The coverage also responds to underinsured motorists: drivers who carry liability insurance but whose limits fall short of your damages. Without UM coverage on your policy, you absorb the shortfall out of pocket or pursue the at-fault driver personally — a process that rarely recovers meaningful amounts.
Washington liability minimums are low. An at-fault driver carrying only $25,000 per person leaves you exposed the moment your injury costs exceed that threshold.

When UM Coverage Applies and When It Does Not
Uninsured motorist coverage responds only when the other driver is legally at fault for the collision. Washington is a fault-based state: the driver who caused the crash bears financial responsibility for resulting damages. If you are found partially or wholly at fault, your UM coverage does not pay your own injuries or vehicle damage — your collision and medical payments coverage, if you carry them, respond instead.
The coverage does not apply to hit-and-run collisions unless your policy includes an uninsured motorist property damage endorsement that specifically covers hit-and-run scenarios. Many Washington carriers exclude hit-and-run from standard UMPD or require you to file a police report within a narrow window, typically 24 to 72 hours. Read your policy's hit-and-run clause before assuming coverage applies.
UM coverage also excludes collisions involving vehicles you own but do not insure. If a household member drives an uninsured car registered to someone in the household and is struck by an uninsured driver, the UM coverage on your other vehicles does not extend to that collision. Every vehicle the household owns and operates must appear on the policy for UM coverage to apply across all exposures.
Passengers injured in your vehicle when an uninsured driver causes a collision can claim against your UM bodily injury coverage. The per-person limit applies to each injured passenger independently, but the per-accident cap remains the binding ceiling.

Washington Minimum Liability Limits
These are the lowest limits a Washington driver can carry and remain legal. An at-fault driver carrying only these minimums leaves you exposed the moment your injury or property damage exceeds them.

Choosing UM Limits for a Multi-Vehicle Household
Match your UM bodily injury limits to your liability limits or higher. The cost to increase UM coverage is typically modest relative to the exposure gap it closes.
Consider medical cost realities when setting per-person limits. The higher UM limit costs more, but it protects against the scenario where an at-fault driver's low limits leave you with six-figure out-of-pocket medical bills.
Compare Carriers That Write Multi-Vehicle UM Coverage
Not every carrier writing in Washington offers the same UM limit options or the same UMPD structure. Some cap UM bodily injury at your liability limits; others let you purchase higher limits independently. Some offer UMPD with no deductible; others require a deductible matching your collision deductible. The policy language controls whether UMPD applies before or after collision coverage when both are present on the policy.
Request UM quotes at multiple limit levels when comparing carriers for your household's vehicles. Carriers writing multi-vehicle policies in Washington include State Farm, Geico, Progressive, Allstate, Farmers, USAA, Travelers, Liberty Mutual, and Nationwide. Each structures UM coverage differently; compare the limit options and the UMPD terms before committing to one policy for all your vehicles.
How UM Coverage Works Across Multiple Vehicles
The per-accident cap is the binding constraint when multiple people are hurt.
Stacking provisions, where allowed, let you multiply UM limits by the number of insured vehicles. Washington does not mandate stacking, and most carriers writing in the state do not offer it. Without stacking, your UM limits remain fixed regardless of how many cars sit on the policy. The vehicle count does not increase the coverage ceiling.

Does Washington require uninsured motorist coverage?
No. Washington does not mandate uninsured motorist coverage. You can legally register and drive with only the state's minimum liability limits: $25,000 per person, $50,000 per accident for bodily injury, and $10,000 for property damage. Those minimums protect others when you cause a crash, not you when someone else does.
What does uninsured motorist bodily injury coverage pay?
Uninsured motorist bodily injury coverage pays medical bills, lost wages, and pain-and-suffering damages when an at-fault driver has no insurance or insufficient limits to cover your injuries. The coverage applies per person and per accident, capping payouts at your selected limits regardless of actual costs.
Does UM coverage apply to all vehicles on my policy?
Yes. When you insure multiple vehicles on one Washington policy, UM coverage applies per person injured, not per vehicle.
Does uninsured motorist coverage pay for hit-and-run collisions?
It depends on your policy's UMPD endorsement. Many Washington carriers exclude hit-and-run from standard uninsured motorist property damage coverage or require a police report filed within 24 to 72 hours. Read your policy's hit-and-run clause before assuming coverage applies.
Can I carry higher UM limits than my liability limits?
Yes. Washington allows you to purchase UM bodily injury limits above your liability limits if the carrier offers them.
How much does uninsured motorist coverage cost?
The cost varies by carrier, your selected limits, and your household's driving history. Request quotes at multiple limit levels when comparing carriers.
Does UM coverage stack when I insure multiple vehicles?
Washington does not mandate stacking, and most carriers writing in the state do not offer it. Without stacking, your UM limits remain fixed regardless of how many vehicles sit on the policy. A household insuring four vehicles has the same per-person and per-accident UM limits as a household insuring one vehicle at the same coverage level.
