2127-AK92 201110 The Regulatory Plan and the Unified Agenda of Federal Regulatory and Deregulatory Actions 2127 National Highway Traffic Safety Administration NHTSA 2100 Department of Transportation DOT Heavy Vehicle Speed Limiters This rulemaking would respond to petitions from ATA and Roadsafe America to require the installation of speed limiting devices on heavy trucks. In response, NHTSA requested public comment on the subject and received thousands of comments supporting the petitioner’s request. Based on the available safety data and the ancillary benefit of reduced fuel consumption, this rulemaking would consider a new Federal Motor Vehicle Safety Standard that would require the installation of speed limiting devices on heavy trucks. We believe this rule would have minimal cost, as all heavy trucks already have these devices installed, although some vehicles do not have the limit set. This rule would decrease the estimated 8991 fatalities caused by crashes involving heavy trucks and buses. It would also increase the fleet fuel efficiency of these vehicles.
