Michigan lawmakers are moving forward with a proposal to keep semis out of the left lane on busy highways.
What’s happening: The bill passed through the House Transportation and Infrastructure Committee on August 19, 2025, and now heads to the full House for a vote.
- If it becomes law, trucks over 10,000 pounds would not be allowed to use the far left lane on any road with three or more lanes.
- There would be exceptions for left turns, road hazards, or construction zone signs allowing trucks in the left lane.
Why it matters: Supporters say the change could help cut down on traffic back-ups and make Michigan highways easier to get through for everyone, including truckers hauling freight across the state.
- Breaking the rule could mean a civil infraction for truck drivers, giving police a clearer way to enforce left-lane use, according to the official bill text.
The bill builds on current regulations that already ask truckers to stay right unless passing. It now waits for a vote by the full House.
