The practice of motorcycles proceeding between lanes of stopped or slow-moving traffic, often at a red light, is referred to by various names, but commonly known as lane filtering. Its legality varies considerably across the United States. Understanding which jurisdictions permit this maneuver is crucial for motorcyclists’ safety and awareness of local traffic regulations.
Permitting this practice can improve traffic flow by reducing congestion. By allowing motorcycles to move to the front of the line, they are removed from the flow of vehicles when the light turns green, thus decreasing the time it takes for all vehicles to accelerate. Additionally, reduced exposure to rear-end collisions for motorcyclists, a common type of motorcycle accident, is a significant potential benefit. Historically, concerns about safety have been the primary obstacle to wider acceptance.
