Utah matches the federal baseline cleanly — 20,000 lb single axle, 34,000 lb tandem, 80,000 lb gross — with the federal bridge formula applied on top and a 10,500 lb per-wheel cap. Dimensions are 8½ feet wide and 14 feet high. Implements of husbandry get an extra 2,000 lb on a single axle off the Interstate system.
