US Congress SB 2033 – A bill to require all new commercial motor vehicles to be equipped with technology to limit maximum operating speed . . . to 65 miles per hour.
A bill to require the Secretary of Transportation to promulgate standards and regulations requiring all new commercial motor vehicles to be equipped with technology to limit maximum operating speed, to require existing speed-limiting technologies already installed in certain commercial motor vehicles to be used while in operation, and to require that maximum safe operating speed of commercial motor vehicles shall not exceed 65 miles per hour.Full Bill Text
UPDATE January 4, 2021: Bill died in committee
Senate Bill 2033 was introduced to the U.S. Senate on June 27, 2019. It has been read twice and referred to the Committee on Commerce, Science, and Transportation. A committee hearing date has not been established.
As noted in the title of the bill, this legislation would put speed limiters on commercial vehicles, including large trucks, with a suggested top speed of 65 mph when many current speed limits are 70, 80 and even 85 mph. The NMA opposes split speed limits on safety grounds, as differential speeds between cars and trucks increase, not decrease the risk of accidents. (See this 2015 national press release by the NMA and the Owner-Operator Independent Drivers Association, which cites several reasons when split limits can be dangerous.)
