Motorcycles are entitled to the full use of a lane on a highway, subject to certain allowances and limitations. Motorcyclists may operate two abreast in a single lane. A motorcyclist may not pass a vehicle in the same lane as the vehicle being overtaken, unless the motorcyclist is overtaking and passing a pedestrian or bicyclist at a distance of at least three feet. A motorcycle may not be operated between lanes of traffic or between adjacent lines or rows of vehicles, a practice commonly referred to as lane splitting, lane filtering, or lane sharing.

The operator of a motorcycle may overtake and pass in the same lane as the vehicle being overtaken. The operator of a motorcycle may only travel between lanes of traffic or between adjacent lines or rows of vehicles when the motorcycle is traveling at a speed of 35 miles per hour or less and not more than 10 miles per hour over the speed of traffic flow. It is a traffic infraction for an operator of a motor vehicle to intentionally impede or attempt to prevent a motorcyclist from operating as permitted under the act.

PRO:  The bill will not increase concerns related to traffic and roadway safety. The bill would allow for greater travel efficiencies and provide congestion relief. Good results have been shown in California and Utah through authorized use of lane splitting and lane filtering. Rear impacts are real dangers to motorcyclists. New automotive technology is no substitute for natural human reactions. The bill would require zero infrastructure updates. Other vehicle operators on road are encouraged to be road vigilantes around motorcycle use. Motorcyclist danger has increased due to failure of vehicle technology to detect motorcyclists and driver overreliance on such technology. The bill would allow motorcycles to clear out of areas where there is congestion and establish a safer stopping margin. Braking on motorcycles is more complex than braking in a car. It is far safer to maneuver between vehicles. Legalizing lane splitting at safe speeds will force other drivers to slow down. The public should be educated if new permissions enacted. Driver's license testing and driver's education should include the bill's new permissions.
 
CON: Bill opposition is based on safety concerns. In 2022, 129 out of 745 traffic fatalities involved a motorcyclist, representing a 37.5 percent increase. Rear end impacts are rare and would not decrease if lane splitting allowed. UC Berkeley study does not indicate that lane splitting is a way to prevent collisions, but that there were less serious injuries when other conditions that aided motorcyclist safety were present, such as protective gear or riding during the day.  Helmet use, speed reduction, and riding less intoxicated are better strategies.  There is not enough room on the road, generally, and drivers are not used to motorcyclist splitting lanes.
