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.
