Lane filtering refers to the practice of a motorcyclist moving between stopped or slow-moving cars, typically at intersections or in heavy traffic. This is often confused with lane splitting, which is riding between moving vehicles, often at higher speeds.
Here’s how the two differ:
Lane filtering is illegal in Oregon as of now. Motorcyclists must stay within their designated lane like any other vehicle.
The current law treats motorcycles like full-size vehicles, which means they cannot move between lanes—even when traffic is at a standstill. However, Oregon has considered making changes to this rule, and recent legislative efforts suggest that this could soon change.
In 2023, Senate Bill 422 was introduced to legalize lane filtering under specific conditions. According to the Oregon State Legislature, the bill passed in the Senate and is now closely monitored by the motorcycle community across the state.
Advocates for motorcycle safety and road efficiency have pushed for legislation that would legalize limited lane filtering in Oregon. SB 422 gained notable attention for its measured and safety-conscious approach.
SB 422 does not legalize all forms of filtering or splitting. It introduces specific conditions under which lane filtering would be allowed:
As highlighted in the Oregon Senate document source, lawmakers believe this “limited, common-sense practice” can ease congestion and protect riders from rear-end crashes.
Like any roadway strategy, lane filtering comes with both upsides and potential hazards. The proposed law aims to strike a balance between safety and convenience.
Benefits include:
Risks to consider:
Motorcyclists must weigh these factors carefully and ensure they are fully trained before engaging in any form of lane filtering, should it become legal. Awareness of surrounding traffic is also crucial, as blind spot accidents remain a leading cause of serious motorcycle collisions in Oregon and across the U.S.
If lane filtering becomes legal, it will introduce new variables in determining fault after a motorcycle accident. The legality of your actions at the time of a crash could heavily influence the outcome of your claim.
Here’s what riders and accident victims should keep in mind:
