Washington — Responding to stakeholder requests, the Federal Motor Carrier Safety Administration (FMCSA) has extended until July 18 the comment period on a proposed rule that would require the installation of speed-limiting devices on trucks, buses and multipurpose passenger vehicles weighing more than 26,000 pounds.

As outlined in a notice published in the May 27 Federal Register, the extension provides interested parties additional time to submit responses. The initial deadline was June 3.

FMCSA, in the May 4 Federal Register, published an advance notice of supplemental proposed rulemaking that expands on a 2016 joint proposal from the National Highway Traffic Safety Administration and FMCSA. The latter is the sole agency listed on the proposal, which doesn’t specify a top speed. The 2016 proposed rule suggested capping speeds at 60, 65 or 68 mph.

FMCSA offers multiple questions on which stakeholders may comment, including:

  • What percentage of the commercial motor vehicle fleet uses speed-limiting devices?
  • If in use, at what maximum speed are the devices generally set?
  • What training or skill sets are needed for motor carriers’ maintenance personnel to adjust or program electronic engine control units to set speed limits?
  • What equipment or tools are needed to adjust or program/reprogram ECUs? How long would the process take, and where can it be completed?
  • Since publication of the notice of proposed rulemaking in 2016, how has standard practice or technology changed as it relates to the ability to set speed limits using ECUs?
