The Federal Motor Carrier Safety Administration (FMCSA) is working to implement a speed limiter mandate that would restrict all heavy-duty commercial motor vehicles (CMVs) to a single top speed across the country, as low as 60 miles per hour. This mandate will be bad for road safety, crash rates, driver retention, and supply chain performance. As the Subcommittee on Highways & Transit convenes a hearing this week to examine policies that will help overcome supply chain challenges, we urge you to prevent FMCSA from moving forward with this controversial mandate. While a speed limiter mandate may be thought of as something affecting only the “trucking” industry, FMCSA’s proposal would apply to every commercial truck weighing over 26,000 pounds. Our coalition represents the numerous industries that would be subject to compliance and enforcement of this mandate, including agriculture, construction, and materials, as well as small, medium, and large trucking companies and state trucking associations.
