The bill amends Section 634 of the Michigan Vehicle Code to clarify and update regulations regarding vehicle operation on roadways. Key changes include the replacement of the word "upon" with "on" in several instances to enhance readability. The bill specifies that drivers must generally operate their vehicles in the right half of the roadway, with exceptions for overtaking other vehicles, navigating around obstructions, and when state or local authority vehicles are engaged in work. Additionally, it allows for flexibility in lane usage for vehicles when streetcars are present or when preparing for a left turn.

Furthermore, the bill introduces new provisions for trucks over 10,000 pounds, requiring them to stay in the rightmost lane on freeways with three or more lanes, except when making a left turn or when special hazards necessitate lane changes. It also establishes that if freeway lanes are closed due to construction, these trucks must adhere to similar lane usage rules. Importantly, local governments are prohibited from enacting ordinances that conflict with these state regulations. Lastly, the bill clarifies that individuals who violate these provisions will be responsible for a civil infraction.
