Lane splitting, also known as lane sharing or white-lining, refers to the practice of motorcycle riders proceeding between lanes of stopped or slowly moving traffic. This maneuver allows motorcyclists to continue forward when congestion would otherwise halt their progress. The legality of this practice varies significantly across jurisdictions.
Permitting motorcycles to navigate between lanes can potentially improve traffic flow by reducing the number of vehicles occupying conventional lanes. It may also offer a safety advantage for riders, mitigating the risk of rear-end collisions common in standstill traffic. However, concerns about rider safety in close proximity to other vehicles remain a key point of debate, influencing legal acceptance.
