Divisible load

Definition

Cargo that can be split between trucks, which is why aggregate gets no overweight permit.

Why It Matters

States may waive axle and gross limits for a load that cannot be broken up, such as a single piece of machinery. Sand and stone can always be split, so the relief never applies and the legal payload is fixed by the axle configuration on the truck. That makes the fleet spec a revenue ceiling and not a preference, and it is the first thing to check when a seller explains that they could haul more if demand allowed.
