UPDATE, as of 5 p.m. Central time Monday, Sept. 25: After naming a 68-mph speed setting for trucks newer than 2003 model year in the DOT update detailed in this story, FMCSA reached out to note the initial information provided in the document was inaccurate and that any specifics about the speed limiter mandate proposal still have to go through the regulatory approval process.
The DOT Significant Rulemakings report now reads that trucks equipped with an "electronic engine control unit (ECU) capable of governing the maximum speed be required to limit the CMV to a speed to be determined by the rulemaking and to maintain that ECU setting for the service life of the vehicle."
FMCSA said the 68 mph speed limit originally included in the report is one of the options being considered for the supplemental notice of proposed rulemaking that the agency is planning to publish before the end of the year, but noted that no decision has been made on the maximum speed limit that will be proposed.
Original story follows:
The U.S. Department of Transportation recently released its Report on DOT Significant Rulemakings, outlining potential timing for rules in the works at a variety of DOT agencies, including the Federal Motor Carrier Safety Administration.
For the first time, the agency signaled the speed at which it hoped to require motor carriers' speed limiters to be set: 68 mph.
As reported in DOT’s previous Significant Rulemakings report last year, FMCSA plans to proceed with a motor carrier-based speed limiter rulemaking by preparing a supplemental notice of proposed rulemaking. The new SNPRM would supersede FMCSA’s joint proposal with the National Highway Traffic Safety Administration in 2016.
