Motorcycle accidents in Washington

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)).
