Is Lane Filtering Legal in Washington?

Lane filtering, also known as lane splitting, is not legal in Washington state. If you ride a motorcycle, you must follow the state's traffic laws, which prohibit riding between lanes of slow or stopped traffic.

Understanding the rules around lane filtering helps you avoid fines and stay safe on the road. This article explains Washington's laws, enforcement, and common mistakes riders make.

What Is Lane Filtering and How Does It Differ From Lane Splitting?

• Both practices require careful control and awareness to avoid accidents with other vehicles.

• Washington law does not distinguish between these terms but bans riding between lanes on public roads.

Even though lane filtering is common in some states, Washington keeps a strict stance against it for safety reasons.
