A number of reports have explored ways to improve transportation efficiency by increasing the length of less than truckload (LTL) twin trailers from 28 feet to 33 feet, while not increasing truck weight. This ConsumerGram reviews the empirical evidence of the proposal, and finds that increasing trailer length would not only significantly lower transportation costs, but it would also improve road safety and reduce fuel costs and greenhouse gas emissions. We estimate the proposal would produce annual economic benefits in excess of $20 billion.
