Long Combination Vehicles (LCV) are configurations of trailers requiring two or more trailers to be added to a tractor to lengthen the size of the load. Some states allow LCV configurations while most states in the Southwest and in the Southeast it is illegal. The only exception to this rule is STAA trailers which are only allowed on the interstate and some roads headed to a terminal city.

Configurations Edit

In this table I will show all the states where LCV is allowed and what trailers can be taken in. Those where it is not allowed will be noted.
