Excerpt from Transport Topics article:
The federal government is proposing that heavy-duty vehicles be equipped with devices that limit their speeds on U.S. roadways but said the limiters will not be required to be tamper-proof.
The proposal, announced Aug. 26, discusses the benefits of setting the maximum speed at 60, 65, and 68 miles per hour but said a final rule could differ, depending on public input and vehicle tests to determine a speed limit for specific vehicle types.
Comments on the proposed rule will be accepted for 60 days after publication in the Federal Register. The rule wouldn’t be effective until three years after the final rule is published in the register.
The joint proposal of the Federal Motor Carrier Safety Administration and National Highway Traffic Safety Administration said limiting the speeds of heavy vehicles will save lives and injuries, cut fuel costs and reduce greenhouse gases and other pollutants.
