Bill > SB1369

This bill adds a new section to Missouri state law (section 304.039) to define and regulate motorcycle lane filtering and lane splitting. The bill defines lane filtering as a motorcycle driving between stopped or slow-moving vehicles in the same lane direction, and lane splitting as driving between fast-moving vehicles. The legislation permits motorcycle operators to overtake and pass vehicles within the same lane or between lanes, but with specific speed restrictions: the motorcycle must travel no more than 10 miles per hour over the traffic flow speed and never exceed 25 miles per hour. While allowing lane filtering, the bill explicitly prohibits lane splitting. The legislation also creates a legal consequence for motor vehicle drivers who intentionally obstruct or prevent a motorcycle from lane filtering, classifying such actions as an infraction. Additionally, the bill empowers the Missouri State Highway Patrol to develop educational guidelines to ensure the safety of both motorcycle operators and other drivers during lane filtering maneuvers. This proposed law aims to provide clear rules for motorcycle movement in traffic while attempting to maintain road safety.
