WEIGHT: The maximum gross weight is 110,000 pounds, subject to the formula W = 800(L+40) where “W” equals the gross weight in pounds and “L” equals the length in feet between the centers of the first and last axles, or the gross weight determined by the Federal Bridge Formula, whichever is least. A single axle shall not exceed 20,000 pounds and a tandem axle shall not exceed 36,000 pounds.

VEHICLE: Vehicles shall not have fewer than six axles or more than nine axles. They shall be configured such that the shorter trailer shall be operated as the rear trailer, and the trailer with the heavier gross weight shall be operated as the front trailer. In the event that the shorter trailer is also the heavier, the load must be adjusted so that the front trailer is the longer and heavier of the two.
Vehicles shall have adequate power to maintain a minimum speed of 20 miles per hour on any grade over which the combination operates and can resume a speed of 20 miles per hour after stopping on any such grade.
