TCA sends a letter to the House Appropriations Committee and encourages its members to call their representatives  ALEXANDRIA, Va. – On July 13, the Truckload Carriers Association (TCA) sent a letter to the House Appropriations Committee opposing a potential amendment to the 2017 Appropriations Bill mandating Twin 33-foot trailers. “This proposed mandate, which overrides the rights of states, will allow the supply chain to force truckload carriers to switch from single 53-foot trailers to double 33-foot trailers, due to their increased cubic capacity. There are more effective ways to meaningfully improve industry productivity,” states the letter written by TCA President John Lyboldt. TCA encourages all member companies to call their representatives and express their concerns with, and opposition to, Twin 33s.
