Is Lane Splitting on a Motorcycle Legal in Washington State?

lane splitting motorcycle washington lawLast Updated: February 1, 2019

One of the most controversial issues when it comes to motorcycle safety along with helmet use is lane splitting. No matter what your stance is on the subject, one thing is clear – lane splitting is not legal in Washington state.

Washington state law (RCW 46.61.608) forbids lane splitting: “(3) No person shall operate a motorcycle between lanes of traffic or between adjacent lines or rows of vehicles.”

Lane splitting is riding a bicycle or motorcycle between lanes or rows of slow moving or stopped traffic moving in the same direction. The practice is sometimes called lane sharing, white-lining, filtering or stripe-riding. Lane splitting can save motorcyclists time, allowing them to bypass heavy traffic.

Illegal lane splitting in Washington state carries a $136 fine. Depending on how erratic the driving is or if the motorcycle is also carrying a passenger, motorcyclists could be charged with reckless driving, illegal passing, endangering others, and so on. But most importantly, lane splitting also increases the risk of a motorcycle accident.

Lane Splitting Can Be Dangerous

California is the only state that allows legal lane splitting, passing a law in 2016, though it had been common practice there for many years without a law preventing it.

A push was made in 2017 by Washington state legislators to make lane splitting legal. A bill passed through the Senate but stalled in the House. Washington State Patrol and the state Traffic Safety Commission argued that lane splitting is unsafe and would not help reduce the fatalities or catastrophic injuries that often result from a serious motorcycle accident.

A 2015 study by the University of California at Berkeley found lane-splitting appeared to be a “relatively safe” strategy if it’s done in traffic moving at 50 mph or less and motorcyclists don’t exceed other vehicles’ speed by more than 15 mph. The study also concluded that lane-splitting motorcyclists were less likely to suffer head or torso injuries or die in a crash than those who didn’t split.

Legislation introduced in 2015 in Washington state that ultimately did not pass would have kept lane splitting illegal, but allowed shoulder driving by motorcyclists in some cases. It also would have opened shoulder driving to motorcycles where transit vehicles could drive on the shoulder.

The bill did not pass. Motorcyclists can receive a ticket for driving on the shoulder which carries a $136 fine.

Lane Splitting Motorcycle Accidents

If an accident occurs while a motorcycle is lane splitting, there's a good chance that the motorcycle rider was at fault for the accident. And if the insurance company finds out afterwards that the motorcyclist was riding dangerously or recklessly prior to the accident, that will severely damage a potential claim. 

But if a motorcyclist can prove that the other driver contributed to the wreck, the motorcycle rider may be partially or fully compensated for their injuries or property damage. If a vehicle was weaving between lanes, the driver was distracted, drunk, or high on drugs, it may be possible for the motorcyclist to prove the driver was at fault. While this type of motorcycle accident isn't that common, the results can be serious and possibly deadly.

If a motorcyclist has been involved in an accident while they were engaging in lane splitting, he or she may have a better chance at recovering compensation through a personal injury claim if they are able to prove the following: 

  • The motorcyclist was riding carefully and legally at the time of the accident
  • The motorcyclist was properly licensed and trained to ride a motorcycle
  • The other driver committed an act more dangerous than lane splitting
