Permit Loads

Some freight is considered a permit load if it is overweight or oversize. An oversize or overweight load is a load that exceeds the standard legal size and/or weight limits for a specified portion of road or highway, requiring a permitting process.  

The national system of Interstate and other major US highways—the National Network (NN)—has travel lanes that are 12 or more feet wide. This allows a margin of nearly two feet on each side of a vehicle or load that is 8.5 feet wide—the maximum legal width in every state. When it comes to width, any load greater than 8.5 feet wide is an oversize “wide” load and a permit and certain safety procedures are required to haul that load.

Height and width are other considerations when it comes to oversize loads. There are no single, specific nationwide values for height or length, but the typical legal state maximum height ranges between 13.5 and 14.5 feet high, and legal overall lengths can extend up to 75 feet under specific conditions. 

While oversize loads may be overweight, overweight loads aren’t considered oversize. Overweight loads can fit within the trailer space but exceed 80,000 lbs, thus requiring a permit.
