(a) A permit issued under this subchapter may authorize the movement of cargo, other than a portable building unit, manufactured, assembled, or distributed by a portable building unit manufacturer, as an authorized distributor if:
(1) the movement is conducted by employees of the manufacturer or by independent drivers and equipment under exclusive contract to the manufacturer during the movement;
(2) the movement is to or from a location where the manufacturer’s building units may be legally stored, sold, or delivered; and
(3) the cargo is compatible with the movement of portable building units in that:
(A) the cargo does not cause the load to exceed applicable height or weight limits; and
(B) the cargo is loaded to properly distribute weight, width, and height to maximize safety and economy without exceeding size or weight limits authorized for movement of portable building units.
(b) If cargo moved under this section exceeds any width limit that would apply to the cargo if it were moved in a manner not governed by this section, the department shall collect an amount equal to any fee that would apply to movement of the cargo if the cargo were moved in a manner not governed by this section in addition to the fee required under this subchapter.
