Statutory authorities classify loads and vehicles as nondivisible if their separation requires more than eight hours to complete using relevant equipment, or where such division would impair function or value, notes the U.S. Department of Transportation.

The maximum gross vehicle weight that the federal government stipulates for the country's highways is 80,000 pounds, according to the U.S. Department of Transportation. The authority's prescribed maximum single axle weight is 20,000 pounds, while the upper limit for tandem axles is 34,000 pounds.
While the federal government stipulates the weight and width limits that apply on the nation's thoroughfares, it does not issue oversize and overweight permits, reports the U.S. Department of Transportation.

For instance, they can issue nondivisible load licenses without considering axle, gross and federal bridge formula requirements, or grant permits to vehicles exceeding the set federal width limit.Learn more about Driving Laws
