The semi trailer length for a 5 axle semi truck trailer varies by state. While federal rules ensure that states cannot reduce the length of a trailer to less than 53 feet on the interstate and access roads, trailer lengths can be shorter than 53 feet on roads that are not federally funded. Also, states can allow longer trailer lengths anywhere in their states, including interstates, if they wish.
