The U.S. DOT released the proposed rule Aug. 26, which would require trucks weighing more than 26,000 pounds to use speed limiting devices (also called governors).
However, the DOT did not specify a speed to which trucks should be governed. The regulatory body suggested three possible speeds for trucks to be governed to: 60 mph, 65 mph or 68 mph.
Overall, the proposal offers little in the way of guidance toward what a final version of the rule could look like, and the DOT is looking for feedback from the trucking industry and equipment manufacturers about the technical aspects of requiring speed limiters on new trucks, as well as trucks already on the roads.
A final rule could take months or years to develop, and the DOT outlines a three-year implementation period once the final rule is published.
