What Is a Vehicle Class Code?
A vehicle class code is a code used to identify individual cars and trucks according to size, axle numbers and type. This code is put on certain driver's licenses and important work documents for approved vehicle use.
There are eight vehicle class codes. Class one is used for 1 to 2 axle passenger vehicles such as normal cars, vans or motorcycles. Class two is used for 3 to 5 axle vehicles such as trailers, single-wheel RVs and limousines. Class three is used for 5 to 9 axle trucks and tractor trailers. Classes 5 through 9 are used for vehicles with dual rear tires and large vehicles such as car carriers or buses.
