After a car accident in Washington, the hardest question is often the simplest to ask and the hardest to answer: whose insurance pays, and for what? The short version is that several different policies can be involved at once. The at-fault driver's liability coverage pays for the harm they caused. Your own Personal Injury Protection (PIP) can pay your medical bills right away, no matter who was at fault. And your underinsured motorist coverage steps in when the other driver has too little insurance, or none at all.
Washington law shapes every one of those layers, and knowing how they fit together is often the difference between a fair recovery and a lowball settlement. This guide walks through each layer, with links to a deeper explanation of each one.
Who pays my medical bills right away?
Usually your own Personal Injury Protection (PIP), if you have it. PIP pays your reasonable medical bills after a crash regardless of who caused it, so you are not waiting on the at-fault driver's insurer before you get treatment. In Washington, every auto insurer is required to offer PIP, and you can only decline it by signing a written rejection (RCW 48.22.085). If you never signed that rejection, you very likely have PIP even if you do not remember buying it. Standard PIP includes at least $10,000 in medical coverage per person (RCW 48.22.095), plus benefits for lost income and other costs.

What if the other driver has no insurance, or not enough?
This is where uninsured and underinsured motorist (UM/UIM) coverage matters, and it is the coverage most people do not realize they have. If the driver who hit you carried no insurance, or carried the state minimum and your injuries cost far more than that, your own UM/UIM coverage can pay the difference. Washington requires insurers to include UM/UIM in your policy unless you rejected it in writing (RCW 48.22.030). Given how many drivers carry only the minimum, this is frequently the coverage that actually makes an injured person whole.

What are Washington drivers actually required to carry?
Not much. Washington's minimum liability limits are $25,000 per person / $50,000 per accident for injuries, and $10,000 for property damage (RCW 46.29.090). Those numbers have not kept pace with the real cost of a serious injury. A single ambulance ride, ER visit, and follow-up care can exhaust a $25,000 limit quickly, which is exactly why your own UM/UIM coverage matters so much. Understanding what the other driver was required to carry, versus what your injuries actually cost, is often the first thing a lawyer looks at.

The insurer says the crash was partly my fault. Does that cut my payout?
It can reduce it, but in Washington it does not eliminate it. Washington follows pure comparative negligence (RCW 4.22.005): your recovery is reduced by your percentage of fault, but you can still recover even if you were partly, or mostly, to blame. If you are found 20% at fault, you recover 80% of your damages. Because that percentage directly controls how much you are paid, insurers have every incentive to assign as much fault to you as possible. Pushing back on an inflated fault percentage is one of the most valuable things a lawyer does on an insurance claim.

What if my own insurance company treats me unfairly?
Washington gives you more protection here than most states. Under the Insurance Fair Conduct Act (RCW 48.30.015), if your own insurer unreasonably denies a claim or payment, you can sue, and a court may award up to three times your damages plus attorney fees. This matters most on first-party claims like PIP and UM/UIM, where you are dealing with your own insurer rather than the other driver's. An insurer that knows the IFCA applies tends to behave very differently.
How the layers stack up in a real claim
In a typical serious-injury case, several of these coverages work together. Your PIP starts paying your medical bills immediately. The at-fault driver's liability coverage is pursued for the full value of your injuries. If that coverage is too small, your UM/UIM fills the gap. Comparative negligence sets the percentage that applies to the whole recovery, and the IFCA sits in the background keeping your own insurer honest. The goal is to use every layer you are entitled to, rather than accepting the first offer from the first insurer that calls.
One deadline that controls everything
None of this coverage helps if you wait too long. As a general rule, Washington gives you three years from the date of the injury to file a personal injury lawsuit (RCW 4.16.080). That is not universal, though. Claims against the federal government run under the Federal Tort Claims Act on a shorter timeline, cases involving common carriers and public agencies can carry their own notice requirements, and other exceptions exist. Because the deadline in your case may be shorter than you expect, the sooner your claim is documented and your coverage identified, the better.
