Statement on Announcement of Notice of Proposed Speed Limiter Rule

Notice of Proposed Rulemaking Requiring Setting of Speed Limiters in Large Trucks to be Released;

TSC Encourages Agency to Apply Regulation to All Large Trucks

Arlington, VA (August 18, 2016): The Truck Safety Coalition, a partnership between Citizens for Reliable and Safe Highways (CRASH) and Parents Against Tired Truckers (PATT), is pleased that the National Highway Traffic Safety Administration’s (NHTSA) promulgated a Proposed Rule requiring speed limiters to be set on large trucks. This standard equipment, which is built into the truck’s engine control module, has actually been manufactured in large trucks since the early 1990s. While requiring speed limiters will advance truck safety and prevent needless truck crash injuries and fatalities, if the agency decides to only apply the rule to new trucks, it will greatly blunt the potential safety benefits.

John Lannen, Executive Director of the Truck Safety Coalition, explained the importance of this rule applying to all large trucks rather than just newer units: “According to findings from the Large Truck Crash Causation Study, more than one out of five large truck crashes were coded as ‘traveling too fast for conditions.’ By capping the speed at which large trucks can travel, this will not only reduce the occurrences of truck crashes, but will also greatly reduce the risk of death or injury by decreasing the impact of the collision.”

“Additionally, the safety benefits of speed limiters have not just been studied, but have also been realized by companies that equipped their trucks with this life-saving technology,” Lannen continued. “One company found that their non-speed limited vehicles were involved in over 40 percent of potentially severe crashes, despite only constituting 17 percent of their fleet. In Ontario, Canada, there was a 24 percent reduction in truck crashes within one year of mandating speed limiters to be set at 65mph. And when the Federal Motor Carrier Safety Administration (FMCSA) studied speed limiters, the agency determined that trucks equipped with speed limiters were nearly 50 percent less likely to be involved in a crash. Clearly this regulation will produce safety benefits, but the extent of those benefits can only be maximized by applying this rule to as many large trucks as possible.”

Lannen, concluded, “While we welcome this safety advancement, we find it necessary to point out that this rule took far too long to be published. The petition to initiate the rulemaking was filed in September of 2006. After a decade and almost 30 delays, it is clear that there is a problem with the rulemaking process. Unfortunately, one of the consequences of this broken system are the thousands of unnecessary speeding-related truck crashes that have occurred between then and now. We look forward to the United States catching up to other leading countries on the implementation of speed limiters, and will continue working to ensure that rather than following, the United States will lead on other safety advancements in trucking, in particular – automatic emergency braking.”
