Click to CallIs Lane Splitting Legal in Oregon? What Riders Need to Know
Lane splitting is still illegal in Oregon as of the date this article was last edited. Oregon law prohibits motorcycle and moped operators from riding between lanes of traffic or between adjacent lines or rows of vehicles, subject to a limited exception for police officers performing official duties. The prohibition was created because of safety concerns. Riding a motorcycle between two other vehicles traveling can lead to unsafe maneuvers and cause an increased chance of collision.
Although the laws are clearly stated, many motorcyclists who live in Oregon believe that permitting lane splitting will lead to greater safety for motorcyclists by reducing congested traffic and increasing the distance between vehicles. Riders need to be aware of the laws that govern lane splitting and any possible future amendments.
Introduction
The legality of lane splitting is not unique to Oregon, as it is being debated in many U.S. jurisdictions. Currently, Oregon motorcyclists are subject to strict rules prohibiting them from engaging in lane splitting. However, the rules prohibiting lane splitting have caused a larger discussion regarding the safety and efficiency of our transportation systems. Many motorcyclists advocate for a change to existing laws, which they feel would create a safer and more efficient system of traffic flow.
In addition to the desire for improved safety and efficiency of traffic flow, the trend towards permitting lane splitting is indicative of an increasingly popular search for creative ways to address traffic congestion. As motorcyclists seek to understand how best to comply with existing laws, the continued discussion of lane splitting creates a sense of urgency regarding finding a middle ground that addresses both the safety aspects of lane splitting and the real-world benefits.
This article will explore all three topics (the current state of affairs, proposed legislation, and expert opinion).
Current Status of Lane Splitting in Oregon
Currently, lane splitting is illegal in Oregon. Therefore, motorcyclists cannot split between two other moving vehicles on multi-lane highways. Clearly established Oregon statutes define the prohibited act of passing another vehicle within the same lane as creating unacceptable safety risks.
However, although there are laws restricting lane splitting in Oregon, the discussion regarding the merits of allowing lane splitting has just begun. Bills concerning the legality of lane splitting were recently discussed in the Oregon Senate. Similar bills were introduced. This indicates an expanding number of people interested in changing these laws.
Thus, until such time as new legislation is enacted, motorcyclists must follow the present laws relative to lane splitting to avoid fines and ensure safe passage.
Understanding Lane Splitting and Lane Filtering
Lane splitting and lane filtering are commonly used to describe different riding situations. Lane splitting provides motorcyclists with the opportunity to navigate between lanes of traffic that are moving at high velocities. Generally speaking, this is exactly what most riders refer to as lane splitting.
On the other hand, lane filtering refers to navigating between stopped or slowed-down vehicles at low speeds. Both practices share common goals: to improve traffic congestion and to promote rider safety. Each has separate rules regarding traffic conditions in which they are permissible and thus presents different challenges. This is for educational purposes only as Oregon law currently prohibits motorcycle riders from operating between lanes or adjacent rows of vehicles, including in stopped or slow-moving traffic.

California stands out, as the state expressly recognizes lane splitting by statute, and Minnesota also permits certain forms of between-lane motorcycle passing under specified conditions. This practice has been extensively studied and regulated in California. Several other states allow more limited forms of lane filtering.
There are several states that allow for limited forms of lane-filtering when traffic comes to a stop. Arizona, Utah, and Montana are among those states.
Lane Filtering in Other States
Several states permit limited forms of lane filtering or between-lane motorcycle passing. Those states include Arizona, Colorado, Minnesota, Montana, and Utah. Hawaii separately allows limited motorcycle use of certain shoulders designated by the state transportation department. Each state has its own set of regulations governing this practice. For example, in Arizona, motorcyclists may filter between lanes when traffic has stopped so long as they do not exceed 15 mph and the posted speed limit is 45 mph or less.
Likewise, Utah permits motorcyclists to filter between lanes when traffic has stopped under similar conditions. In Colorado, traffic must come to a complete stop before motorcyclists may engage in filtering between lanes; further, they may filter between lanes at speeds no greater than 15 mph.
Hawaii law allows the state Department of Transportation to designate certain shoulders for limited motorcycle use when traffic is stopped. Additional speed and direction-of-travel restrictions apply, where authorized.
Proposed Legislation: SB 422
SB 422 was passed by the Oregon State Senate in March of 2023, and would have made major amendments to the current laws regarding motorcycle Lane Splitting. The proposed law would allow motorcyclists to split lanes where the speed limit is 50 mph or higher, and the traffic around the motorcycle is moving at a rate of 10 miles per hour or less. Unfortunately, SB 422 did not become law and remained in a House committee when the 2023 legislative session ended. The proposal included additional safety restrictions, including limiting motorcycles to no more than 10 mph above the speed of surrounding traffic.
Currently, as of this article’s last edited date, Oregon has general provisions against Lane Splitting or Lane filtering, unless a specific exemption exists.

Potential Aspects of Lane Splitting
Lane Splitting offers many advantages for traffic flow and for the safety of motorcyclists. It may alleviate traffic congestion in busy cities.
When using this method of navigating congested streets, motorcyclists can effectively move through traffic by inserting themselves between two lines of cars. This results in fewer total numbers of vehicles in each line of traffic, which helps to facilitate smoother traffic flow. Furthermore, by keeping the flow of motorcyclists consistent while passing between lanes, the amount of time spent in traffic decreases.
Additionally, Lane Splitting can reduce hazards for motorcyclists, as well as promote enhanced safety. For example, studies reveal that motorcyclists are less susceptible to being rear-ended while engaging in Lane Splitting because they continue to move rather than sit stationary in traffic. As a result, Lane Splitting minimizes the likelihood of rear-end collision incidents that represent one of the most common threats to motorcyclists while driving through congested urban traffic.
Lane Splitting has environmental benefits as well. Because motorcyclists are able to minimize idling while sitting in congested traffic, there are reduced emissions produced by their engines.
Ultimately, Lane Splitting may provide increased control over the travel path for motorcyclists, particularly in chaotic city environments.
Addressing Safety Concerns
Critics have voiced several reasons why they believe Lane Splitting poses a threat to motorcyclists’ safety. For instance, critics claim that riders are vulnerable when operating within larger vehicle blind spots. However, studies demonstrate that Lane Splitting does not generate excessive crash risks and may actually reduce the incidence of certain accidents despite hazardous conditions.
Motorcyclists can employ several techniques to lessen their exposure to danger while engaging in Lane Splitting. Using brightly colored clothing or applying reflective strips increases visibility to nearby motorists. Avoiding blind spots in large vehicles and ensuring that brakes and clutches remain covered in hazardous zones contribute to lowering the chances of accidents occurring. Lastly, remaining alert and prepared to respond rapidly to unexpected actions made by surrounding drivers and other vehicles enables motorcyclists to operate safely through congested traffic patterns.
How Lane Splitting Could Change Riding in Oregon
If Oregon legalizes Lane Splitting, it would have a substantial impact on riding throughout the state. Proponents advocate for legalizing Lane Splitting due to its ability to ease congestion on Oregon’s highways by enabling motorcycles to navigate through slower-traffic lanes.
Implementing harsh penalties for violators will ensure adherence to regulations, thereby increasing safety for all road users. The introduction of new regulations and safety guidelines could lead to improved road safety and efficiency for all users.
Expert Opinions on Lane Splitting
Research from UC Berkeley’s SafeTREC substantiates that lane splitting is safe for motorcyclists. Data collected from California’s enhanced motorcycle collision data project demonstrates that Lane-Splitting motorcyclists had lower injury rates in a collision than those who chose not to use this option. This data supports the theory that when executed properly, Lane Splitting can be safer for motorcyclists.
Data further shows that motorcycle riders who choose to use Lane Splitting frequently wear additional protective equipment like helmets and gloves, which may explain why they had better protection during crashes than riders who do not use this option. The researchers also found that injury risk increased as traffic speeds and the rider’s speed relative to surrounding traffic increased.
