Is Lane Splitting Legal in Washington?
If you’ve ever been stuck in traffic on I-5 or crawling through downtown Seattle, you’ve probably seen a motorcycle snake its way between the cars. Maybe you’ve even wondered, “Can they really do that?” That little move is called lane splitting, and whether it’s legal or not depends a lot on where you are. So let’s get straight to it—is lane splitting legal in Washington?
The short answer: No, it’s not. But like most things related to law and motorcycling, the full story is a bit more complex. Buckle up—or helmet on—we’re diving into the ins and outs of lane splitting laws in Washington State.
Understanding Lane Splitting
Definition of Lane Splitting
Lane splitting is when a motorcycle rides between two lanes of slow-moving or stopped traffic. It’s not the same as lane filtering, which is usually done at stoplights, or shoulder surfing, which involves riding on the road shoulder. They’re often confused, but the legal implications can be very different.
Common Reasons Riders Lane Split
Riders lane split for a few reasons:
- To save time: Who likes waiting in traffic?
- To avoid overheating in traffic jams: Some motorcycles don’t have the cooling systems to sit still for long.
- To reduce the chance of rear-end collisions: Being squeezed between distracted drivers is no fun.
Motorcyclists argue that it can actually be safer than sitting still between two cars, especially in bumper-to-bumper traffic.
The Legal Landscape of Lane Splitting in the U.S.
States Where Lane Splitting Is Legal
As of now, California is the only state that fully legalizes lane splitting, thanks to a 2016 law that made it the first in the nation to recognize it officially. In Utah and Montana, lane filtering—a more restricted version—is legal in certain scenarios.
States That Explicitly Ban Lane Splitting
Most U.S. states, including Washington, prohibit or don’t clearly define lane splitting, which often leaves it in a legal gray zone. Some even have specific laws stating it’s illegal to operate a vehicle in between lanes of traffic.
So… Is Lane Splitting Legal in Washington?
Current Washington State Law
Let’s be clear: Lane splitting is not legal in Washington. According to RCW 46.61.608(3):
“No person shall operate a motorcycle between lanes of traffic or between adjacent lines or rows of vehicles.”
That’s about as clear as it gets. If you’re caught lane splitting, you could face a traffic infraction, fines, and potentially worse if it causes an accident.
Is There a Gray Area?
Even though the law prohibits it, enforcement can vary. Some motorcyclists claim that in lighter situations—like slowly passing two stopped cars—it might be overlooked. But that’s a gamble. The Washington State Patrol has stated that riders should not split lanes under any circumstances.
Proposed Lane Splitting Bills in Washington
Past Legislative Attempts
There have been attempts to change the law. In 2017, Senate Bill 5254 proposed allowing lane splitting on roads with speeds of 50+ mph and traffic moving under 10 mph. It gained traction but ultimately died in committee.
Future Possibilities
Advocates haven’t given up. Each year, motorcycle groups push for updated laws, pointing to California’s success as evidence. While there’s no bill currently in motion (as of 2025), the conversation is far from over.
