The U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) and Federal Motor Carrier Safety Administration (FMCSA) today announced a 30-day extension of the public comment period for a September 7, 2016 Notice of Proposed Rulemaking which would require all newly manufactured U.S. trucks, buses, and multipurpose passenger vehicles with a gross vehicle weight rating more than 26,000 pounds to be equipped with speed limiting devices. 

The new public comment deadline of December 7, 2016, will provide all interested parties sufficient opportunity to fully develop and submit comments and evidentiary materials to the agencies via www.regulations.gov. 

Requiring speed limiting devices on heavy vehicles could save lives, as well as an estimated $1 billion in fuel costs each year.
