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

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: Occurs at lower speeds, typically under 10 mph.
• Lane Splitting: Involves weaving between faster-moving vehicles, sometimes in freeway traffic.
• Legality: Lane filtering is under review in Oregon, while lane splitting remains illegal.
• Purpose: Filtering is used to reduce rear-end collisions and decrease traffic congestion for motorcycles.

Current Legal Status of Lane Filtering in Oregon

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.

Recent Efforts to Legalize Lane Filtering in Oregon

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.

What You Need to Know About the Proposed Legislation

SB 422 does not legalize all forms of filtering or splitting. It introduces specific conditions under which lane filtering would be allowed:

• Only on roads with a speed limit of 50 mph or higher.
• Only when the road has at least two lanes going in the same direction.
• Only when traffic is stopped or moving at 10 mph or less.
• Prohibited in work zones, on road shoulders, and near opposing traffic lanes.

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.

Potential Risks and Benefits of Lane Filtering for Motorcyclists

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:

• Reduced risk of rear-end collisions, especially at traffic lights.
• Improved traffic flow, particularly during peak commuting hours.
• Shorter commute times for riders.

Risks to consider:

• Increased visibility challenges for drivers who may not expect motorcycles between lanes.
• Possible confusion in enforcement during the early stages of legislation.
• Danger from sudden lane changes by inattentive drivers.

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.

How Lane Filtering Can Affect Your Accident Claim

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:

• If lane filtering is legal and done correctly, it may strengthen your case by showing you followed traffic rules.
• If it remains illegal, filtering could be used to argue comparative fault, potentially reducing your compensation.
• Insurers may scrutinize motorcycle accident claims more closely in light of new rules.
• Accident reports and witness statements will become even more critical in potential lane filtering cases.

Understanding these legal nuances is essential for protecting your rights after a collision.
