New Study Finds Significant Safety Benefits of Limiting Truck Speeds

March 28, 2012

ARLINGTON, VA - New research released this week by the Federal Motor Carrier Safety Administration (FMCSA) confirms the clear safety benefits of using technology to electronically govern and limit the top speed of commercial trucks.

"This study confirms what ATA has been saying for years – speed kills and one of the most effective ways to prevent hundreds, if not thousands, of crashes on our highways is to slow all vehicles down, including large trucks," American Trucking Associations President and CEO Bill Graves said. "ATA petitioned FMCSA and the National Highway Traffic Safety Administration six years ago to mandate the use of speed limiters on all commercial motor vehicles manufactured since 1992 to save lives and make our industry safer. This study strengthens ATA's case and we call on both agencies to swiftly move forward with rulemakings to ensure that these devices are required on as many trucks as possible."

The study team, which included the American Transportation Research Institute and the Virginia Tech Transportation Institute, found that "multiple analyses indicated a profound safety benefit for trucks equipped with an active [speed limiter]."

Further, the study concluded that complaints from critics of this technology were not substantiated by the data.

"Domain research on the potential downside of speed deviations among vehicles that could occur due to the interaction of [speed limiter]-equipped vehicles and those without [speed limiters] seems to be far outweighed by the significant safety benefits associated with a reduction in absolute speed afforded by [speed limiters]," the study said.

"Slowing down traffic is the most important step toward improving highway safety," Graves said. For this reason, ATA's policy calls for a national 65 mph speed limit for all vehicles and ATA's broad safety agenda calls for a speed limiter mandate.  "The Department of Transportation should be commended for sponsoring this comprehensive field study and, in addition to using its findings, it should be a model for how all safety regulations are researched and supported. We hope in the future DOT will have the political will to recognize that speed is the single greatest contributor to highway crashes and prioritize its regulatory initiatives accordingly."

    I do not afree with this speed limiter finding at all and will not support it. While there are populated areas of the U S that would apply, there is much open country where 75 MPH is safely driven every day by all types of vehicles on the Interstates, and must be maintained! I E I 80, I90, ETC.
