Submit a Motor Vehicle Collision Report to the Washington State Patrol within 4 days if police did not investigate the crash, and watch the larger deadline: Washington injury lawsuits usually must be filed within 3 years.

The common bad advice is: "If several insurers are blaming each other, just wait until they sort it out." No. That delay helps them, not you. Evidence disappears, app data gets overwritten, surveillance footage from a Bellevue shopping center gets deleted, and tax-season debt pressure pushes people into cheap settlements before fault is pinned down.

What you need is proof tying each party to a specific failure.

Start with the basics: photos of vehicle positions, damage, skid marks, loading-zone markings, store entrances, warning signs, and any blocked sightlines. If your injury was a crush injury or blunt-force trauma, get the full ER chart, imaging, and billing records showing exactly how the injury happened and when symptoms started.

Then lock down the business records:

• DoorDash/Uber/Amazon Flex app logs showing you were active on a delivery
• Time-stamped pickup/dropoff records
• Driver messages, route screenshots, and GPS history
• Incident reports from the property owner, store, or security company
• Names of all contractors on site, including valet, delivery, or maintenance companies
• Surveillance video requests sent immediately

Washington uses comparative fault. In many multi-party cases, fault gets split by percentage. But if you were not at fault, Washington law can make defendants jointly and severally liable for the full damage award, which is why insurers fight so hard over your share of fault.

Also keep every health insurance, PIP, and reimbursement letter. Subrogation claims can eat into a settlement fast, especially when medical debt is piling up. If one carrier pays early, it may demand repayment later. Do not sign a broad release for one insurer until you know whether it wipes out claims against the others.
