Idle Reduction and Natural Gas Vehicle (NGV) Weight Exemption
Any motor vehicle equipped with an auxiliary power unit (APU) or other idle reduction technology may exceed the gross, single axle, tandem axle, or bridge formula weight limits by up to 550 pounds (lbs.) to compensate for the weight of the technology. To be eligible for the weight exemption, the vehicle operator must be able to provide written proof or certification of the weight of the APU or idle reduction technology, and demonstrate or certify that the technology is fully functional at all times.
Furthermore, NGVs may exceed the weight limits by an amount equal to the difference of the weight of the natural gas tank and fueling system and the weight of a comparable diesel tank and fueling system. The NGV must not exceed a maximum gross vehicle weight of 82,000 lbs. (Reference Iowa Code 321.463)

Alternative Fuel Vehicle (AFV) Conversion Registration
When a motor vehicle is modified to use a different fuel type or more than one type of fuel, the vehicle's registered owner must notify the county treasurer of the new fuel type or alternative fuel types within 30 days. If the vehicle uses, or may use, a special fuel, the county treasurer will issue a special fuel identification sticker. (Reference Iowa Code 321.41)

At least 10% of new light-duty vehicles purchased by institutions under the control of the state fleet director, including the Iowa Department of Transportation, Board of Directors of Community Colleges, Board of Regents, Commission for the Blind, and Department of Corrections must be capable of operating on alternative fuels. Vehicles and trucks purchased and directly used for law enforcement and off-road maintenance work are exempt from this requirement.
