NRMCA Comments on DOT Truck Size, Weight Study

Earlier this week, NRMCA submitted comments to the U.S. Department of Transportation (DOT) regarding the Federal Highway Administration’s (FHWA) congressionally mandated study analyzing how trucks impact our nation’s roadways. FHWA is collecting comments on the finalized study which will be incorporated into a report to be submitted to Congress later this year.

NRMCA’s comments highlighted the glaring lack of truck configurations considered in the study. FHWA made the determination to only consider trucks with five or more axles. NRMCA noted that such a shortsighted determination excludes a large segment of trucks on our nation’s roadways from the study, including 3- and 4-axle trucks which comprise roughly 70% of concrete mixer trucks operating in U.S. ready mixed concrete markets. NRMCA continued to argue that by deciding to not include such a large segment of trucks, FHWA’s study is incomplete and not representative of the true relationship trucks have to our nation’s roadways.
