ederal Commercial Vehicle Size Limits on the National Network
Overall vehicle length
No federal length limit is imposed on most truck tractor-semitrailers operation on the National Network.
Exception: On the National Network, combination vehicles (truck tractor plus semitrailer or trailer) designed and used specifically to carry automobiles or boats in specially designed racks may not exceed a maximum overall vehicle length of 65 feet, or 75 feet, depending on the type of connection between the tractor and trailer.
Trailer length
Federal law provides that no state may impose a length limitation of less than 48 feet (or longer if provided for by grandfather rights) on a semitrailer operating in any truck tractor-semitrailer combination on the National Network. (Note: A state may permit longer trailers to operate on its National Network highways.)
Similarly, federal law provides that no state may impose a length limitation of less than 28 feet on a semitrailer or trailer operating in a truck tractor-semitrailer-trailer (twin-trailer) combination on the National Network.
Vehicle width
On the National Network, no state may impose a width limitation of more or less than 102 inches. Safety devices (e.g., mirrors, handholds) necessary for the safe and efficient operation of motor vehicles may not be included in the calculation of width.
Vehicle height
No federal vehicle height limit is imposed. State standards range from 13.6 feet to 14.6 feet.
Not allowed
Most roads which are referred to as service roads are simply public access roads which anyone is allowed to drive on.
The laws pertaining to unmotorized vehicles differ from state to state and in some communities.
Roads
Depends on the wheelbase, and what state law allows on secondary roads. 54,000 lbs. is the norm on secondary roads, whereas 50,000 to 54,000 may be allowed on the Interstate, depending on the vehicle's wheelbase.
