The U.S. Department of Transportation’s Federal Motor Carrier Safety Administration and the National Highway Traffic Safety Administration today announced a 30-day extension of the public comment period for the September 7, 2016, Notice of Proposed Rulemaking, which would require all new U.S. trucks and buses weighing more than 26,000 pounds be equipped with speed-limiting technology. It has been estimated that speed limiting devices on commercial motor vehicles will save $1 billion per year. The new deadline for public comments is December 7, 2016.
