Motorcycle accidents in Washington
Riders are more likely to be seriously hurt in a crash and more likely to be blamed for it. Two rules come up in almost every motorcycle claim: the helmet law and the lane-splitting law.

Washington’s helmet law
Every motorcycle rider and passenger must wear a helmet.
Not wearing a required helmet can be raised to argue that part of a head injury was the rider’s own fault. It does not excuse the driver who caused the crash.

Lane splitting
Lane splitting is not legal in Washington.

Bias against riders
The most common motorcycle crash is a car turning left across the rider’s path, with the driver saying they “never saw” the bike. Not seeing a vehicle that was there to be seen is a failure to keep a lookout, not a defense — but adjusters routinely open with the assumption that the rider was speeding.
Fault and deadlines
Under Washington’s pure comparative fault rule, a driver found 30% at fault recovers 70% of their damages, and a driver found 80% at fault still recovers 20%.
Washington’s injury deadline is 3 years (Rev. Code Wash. § 4.16.080(2)).
