Speed Limiters

In 2015, 4,067 people were killed in large truck crashes in the United States

Speed Limiters


  • On average, more than 1,000 lives are lost annually to speeding Commercial Motor Vehicles (CMVs).
  • Speeding (i.e., exceeding the speed limit or driving too fast for conditions) was a contributing factor in 7.5 percent of all reported large truck crashes in 2015.
  • The Large Truck Crash Causation Study (LTCCS) reported that 22.9 percent of large trucks involved in all types of crashes, and 15.2 percent of large trucks involved in a two vehicle crash with a passenger car, were coded as traveling/driving too fast for conditions.

Requiring Speed Limiters be Set on All Large Trucks The Truck Safety Coalition (TSC) supports a rule requiring all large trucks with existing speed limiting technology to be capped at a maximum speed of 60 mph. This regulation is long overdue as speed limiters have been installed in most trucks since the 1990s. By limiting the speed of heavy vehicles to 60mph, the National Highway Traffic Safety Administration (NHTSA) estimates that 162 to 498 lives could be saved. Additionally, the FMCSA compared fleets that had speed limiters to fleets that did not, and they found that “trucks equipped with speed limiting devices had a statistically significant lower speed-limited-relevant crash rate compared to trucks without speed limiting devices.”
