Barletta Amendment 24 to H.R. 7, which is part of the Transportation Reauthorization Bill, was approved by a 33-22 vote in the House on Feb. 3. This amendment strikes many of the Bill's provisions that increase maximum truck sizes and weights on interstates and some other federal-aid highways. The Bill had proposed increasing the current 80,000-lb. federal weight limit to 88,000 lbs. for car carriers and 97,000 lbs. for six-axle trucks. The amendment requires USDOT to conduct a comprehensive three-year study of the safety and pavement performance impacts of the widespread use of bigger trucks.
