Bill > HB4522

This bill modifies Michigan's vehicle code regarding lane usage, primarily focusing on highway and freeway driving regulations. The bill requires drivers on roadways with two or more lanes traveling in the same direction to drive in the extreme right-hand lane, with some exceptions such as preparing for a left turn, avoiding obstructions, or when lanes are occupied by continuous traffic. For freeways with three or more lanes, the bill specifically restricts trucks over 10,000 pounds, truck tractors, and vehicle-trailer combinations from driving in the leftmost lane, except when making a left turn, addressing a safety hazard, or during road construction. The bill adds a new provision addressing lane usage when a freeway is reduced to two usable lanes due to construction, mandating that larger vehicles use the rightmost lane under similar conditions. The bill also prevents local governments from creating ordinances that conflict with these lane usage regulations and maintains that violations result in a civil infraction. The changes aim to improve traffic flow and safety by providing clear guidelines for lane usage, particularly for larger vehicles on multi-lane highways.
