The Arizona Department of Transportation (ADOT) must issue a special license plate to dedicated AFVs. Dedicated AFVs are defined as vehicles powered exclusively by propane, compressed natural gas, electricity, or hydrogen. There is no limit to the number of AFV license plates ADOT can issue. The Arizona Department of Environmental Quality (ADEQ) must inspect vehicles converted to operate solely on alternative fuel and issue an Alternative Fuel Certificate before converted vehicles may receive the AFV special plate. State or agency directors who conduct activities of a confidential nature and use AFVs are exempt from the requirement to display an AFV special license plate. For more information, see the ADOT AFV and ADEQ Vehicle Emissions Testing website.
