The Economic Impact Of Allowing Twin 33s On Interstate Highways
Replacing Twin 28s with Twin 33s will reduce carbon emissions, fuel usage, trucks on the road, and the number of crashes every year.
Advanced trucking technology like platooning will make freight safer and more efficient.
States allowing long combination vehicles (LCVs) and Twin 33s trailers are already making strides towards improved roadway safety, enhanced environmental sustainability, and more productive interstate commerce.
Compared with the existing 28 ft double trailer configuration, the proposed 33 ft double trailer combination shows improved productivity by volume, and 16% improved fuel use and reduced emissions.
Increasing the length of twin trailers just 5 feet will decrease emissions, take trucks off the road, lead to fewer accidents and save fuel.
