Speed Limiters Notice of Intent (FAQs)
The National Roadway Safety Strategy identified speed as a significant factor in fatal crashes and speed management as a primary tool to reduce serious injuries and fatalities. The number of commercial motor vehicle (CMV) crashes in which speed is listed as a contributing factor is unacceptable. A carrier-based approach could provide the opportunity to compel fleets that are not currently using speed limiters to slow down their CMVs within a relatively short period.
FMCSA anticipates publishing the SNPRM in 2023. The rulemaking requires the Office of Management and Budget review before publication. FMCSA will consider the information obtained through the NOI comments informing the proposal.
No. FMCSA intends to move forward with a separate motor carrier-based speed limiter rulemaking.
Yes. Over five years ago, FMCSA issued the NPRM, and perspectives may have changed. The new rule will be carrier-based, and FMCSA wants to know how that affects your views. Additionally, FMCSA will provide updated data that can help inform the best possible proposal.
No. The NOI informs the public of FMCSA’s plans to move forward with the speed limiter rulemaking process. FMCSA is not yet proposing regulatory language to amend the Federal Motor Carrier Safety Regulations or a specific speed limit to set the electronic engine control unit (ECU). The NOI solicits comments on questions that will inform the SNPRM, including proposals to amend the regulations and set a speed limit.
Through the NOI, FMCSA is requesting the public’s help in providing data on the programming or adjustment of the ECUs to assist in imposing speed limits on CMVs. The responses to questions will inform the proposals FMCSA will describe in the SNPRM.
Please provide your comments within 30 days after the NOI is published in the Federal Register.
