Green Driver State Incentives in Arizona

Arizona works hard to preserve its natural beauty, and therefore encourages drivers to go green with numerous money- and time-saving incentives. Whether you drive an electric car (EV), hybrid, alternative fuel vehicle (AFV), or some other fuel-efficient vehicle, keep reading for more on how you and the environment can benefit.

As the state becomes more focused on the environment, its vehicle-related laws might also change. Stay up to date by consulting your local Motor Vehicle Division (MVD) branch and the Alternative Fuels Data Center.

Arizona Vehicle Registration and Emissions Testing

Arizona does not require all vehicles to undergo an emissions test as part of first-time vehicle registration and registration renewal. In fact, only residents whose vehicles are registered* in the emissions test areas located in metro Phoenix (Area A) and metro Tucson (Area B) are subject to the emissions requirement.

*If you drive an alternative fuel vehicle that's either registered in or used to commute to the areas mentioned above, also check out our page on green vehicle laws for AFV registration and license plate details.

Emissions Test Exemptions

Keep in mind, the MVD exempts the most of the following fuel-efficient and green vehicles from emissions testing:

  • Electric vehicles.
  • Solar-powered vehicles.
  • Hydrogen-powered vehicles.
  • Gas and alternative fuel vehicles with current model year and previous 4 model years (excluding reconstructed vehicles)

If you own an OEM alternative fuel vehicle, your registration renewal should indicate your exemption (look for a message regarding an in-lieu fee). Otherwise, you'll need to prove to the Arizona Department of Environmental Quality (ADEQ) that your vehicle is an OEM AFV by either:

  • Submitting original documentation.
  • Having your vehicle inspected by the ADEQ.

For full details on Arizona emissions test exemptions and requirements, consult the ADEQ’s site, call (877) 692-9227, or refer to our page on AZ emissions and smog testing.

If your vehicle requires an emissions test, scroll down to our locator widget at the bottom of the page to find the nearest inspection station.

Auto Insurance Discounts for Eco-Friendly Driving and Green Vehicles

Some Arizona auto insurance providers offer insurance discounts for having green driving habits and/or driving a fuel-efficient vehicle. Consult your car insurance company about potential green vehicle discounts such as:

  • Hybrid auto discounts.
  • Alternative fuel vehicle (AFV) discounts.
  • Economy car discounts.
  • Low-mileage discounts.
  • Pay as you drive discounts.

Auto insurance discounts vary by provider and circumstances. For example, you might receive a 10% discount on car insurance for owning or leasing a hybrid car, while maintaining low mileage can earn an even higher auto insurance discount.

If your current AZ auto insurance carrier doesn't reward eco-friendly driving, find one that does. Compare auto insurance rates online and save some green for going green.

Full-Time AZ HOV Lane Access for Alternative Fuel Vehicles

Drivers of alternative fuel vehicles (AFV) can use Arizona high occupancy vehicle (HOV) lanes regardless of the time of day and their number of passengers. To do so, your vehicle must display a current AFV special plate or sticker.

By definition, an alternative fuel vehicle is powered by any of the following alternative fuels:

  • Electricity.
  • Solar.
  • Alcohol.
  • Compressed natural gas.
  • Liquefied natural gas.
  • Hydrogen.
  • 70% alternative fuel/30% gasoline blend.

Arizona AFV and Electric Car Parking Incentives

If you drive an alternative fuel vehicle, you can park in designated carpool operator parking spaces without penalty. Arizona Statutes 28-877 covers the specifics. See the list of alternative fuels in the section above to determine if your vehicle qualifies as an AFV. And if so, learn more on how to register your AFV in Arizona.

If you drive an electric vehicle, you can park in spaces specially designated for electricity-powered vehicles, unless your EV bears an alternative fuel vehicle special plate or sticker pursuant to Arizona Revised Statutes 28-2416.
