DOT’s Speed-Limiter Proposal to Add Older Trucks

An upcoming federal rule mandating speed limiters on heavy-duty trucks will include the requirement that current vehicles be retrofitted as well as new trucks rolling down assembly lines, according to an official of the National Highway Traffic Safety Administration.

Christopher Bonanti, NHTSA associate administrator for rulemaking, said the Federal Motor Carrier Safety Administration has joined the rulemaking process, so that the speed-limiter mandate can apply to all trucks and not just new models.

A recent Department of Transportation report on rulemakings had said the speed-limiter proposal could be out as early as March. However, Bonanti said that date could be delayed now that FMCSA has joined the process.

“We hope to get that [notice of proposed rulemaking] published . . . later in 2014,” Bonanti said at American Trucking Associations’ Management Conference & Exhibition in Orlando, Fla., late last month.

“We normally do our rule, and then FMCSA does its rule, but this rule is going to be a joint rule,” Bonanti said. “We’re taking into consideration the safety requirements associated with what is being considered, and also the enforcement mechanisms associated with it.”

FMCSA spokesman Duane De-Bruyne said the agency expects the rule to reduce 1,115 fatal accidents annually.

Bonanti said a federal study showed that speed limiters could save lives and increase fuel economy.

The rule is being crafted in response to petitions filed in 2006 by American Trucking Associations, Road Safe America and nine motor carriers.

In early 2011, NHTSA said in a Federal Register announcement that the petitions merited “further consideration through the agency’s rulemaking process.”

At that time, NHTSA originally said it expected to complete the proposed rule in 2012. Despite the delay, Bonanti’s announcement last month was well-received.

In 2006, ATA said a rule should require that speed limiters be set no higher than 68 mph. However, ATA has since revised its policy and asked that the maximum be 65 mph, Osiecki said.

Owings said that roughly 70% of the trucks in the United States already have their speed limiters set and as a result have reported that they have reduced crashes and saved money on fuel and maintenance….
