This bill amends Section 321.463 of the Iowa Code to allow vehicles powered primarily by natural gas or electric battery to exceed the maximum gross weight limit of 80,000 pounds, permitting these vehicles to weigh up to 82,000 pounds. The previous requirement that the excess weight must be attributable to the natural gas tank and fueling system has been removed, simplifying the regulations for these vehicles. The bill specifically inserts language to include electric battery-powered vehicles alongside those powered by natural gas, thereby expanding the scope of the weight exemption.

Additionally, the bill establishes penalties for vehicles that exceed the allowable weight based on their number of axles and the distance between axles. The fines for exceeding the weight limit range from $12 to $2,200, plus an additional charge of 10 cents per pound for every pound over 20,000 pounds above the limit. This legislative change aims to support the use of alternative fuel vehicles by providing more flexibility in weight regulations while maintaining a framework for penalties for non-compliance.
