DOT Extends Speed-Limiter Rule Comment Period

A 30-day extension of the public comment period for a proposed truck speed-limiter rule was announced today by the National Highway Traffic Safety Administration and the Federal Motor Carrier Safety Administration.

The new deadline for comments is Dec. 7.

The proposed rule would require all newly manufactured U.S. trucks, buses, and multipurpose passenger vehicles with GVWR over 26,000 pounds to be equipped with speed-limiting devices. Motor carriers would be responsible for maintaining the speed limiters at or below the designated speed for the service life of the vehicles.

According to the Department of Transportation, the proposed rule “discusses the benefits of setting the maximum speed at 60, 65, and 68 miles per hour, but the Agencies will consider other speeds based on public input.”

That nebulous aspect drew heavy fire last month from the head of trucking’s biggest lobby. Chris Spear, president and CEO of the American Trucking Associations, slammed the rule during an Oct. 4 press conference. “The various differentials in speed from what this rule proposes and what state speed limits are is dangerous,” he said. “What is this proposal? Three speed limits, not one. No studies to back it up. And no national cap on limits to address speed differentials."

“Our policy focus now is to develop comments on this proposal, which in my humble opinion, is flawed,” Spear continued. “We cannot afford to elevate risks for the motoring public with a rule that does not take into account the danger of differential speeds for cars and trucks."

Spear also said the two agencies have “the responsibility to study [what they’ve proposed] and come to a consensus about [setting] one speed and one national limit— not three speeds and no national limit [as is laid out in the proposal].”

To date, over 3300 public comments have been filed on the proposal. Existing comments may be viewed and new comments submitted online via this link.

    I am a truck driver and although I agree slowing trucks down helps reduce accidents, my Biggest concern is speed limits in some places make a road hazzard for truckers and the motoring public. In Nevada some stretches of highway the limit is 80. In California its 70 for cars and statewide 55 for trucks. Tell me speed differentials are not dangerous and I'll tell you that you are high on drugs.

    Whether with human truck drivers or robots - motor vehicle accidents involving trucks WILL still occur. Most truck drivers are good, safe drivers; hard working men. But the few who arent are giving reason and power to politicians and companies to dictate to the majority of good truckers how we are to make a living. Its NOT right. How about giving our truckers more incentive for safe driving? We have to think of other options. Happy truckers drive safe!!! If we continue to burden truckers with regulations, disgruntled drivers arent going to have a "let's drive safe" attitude.
