For those who operate eco-friendly vehicles, Wisconsin offers several green driver incentives including emissions testing exemptions, tax refunds, weight exemptions, biodiesel fuel use incentives, and even special grants, loans, and tax credit programs for businesses such as farms.
The DOT determines when it's time for your vehicle to undergo a smog and emissions check, but you'll ALWAYS have to register your vehicle before your first-time vehicle registration and during registration renewal. Any other time? You'll receive notice.
However, if you drive certain green vehicles, you're off the hook. The following eco-friendly vehicles are exempt from smog checks:
Diesel-powered vehicles with a model year 2006 and older.
Motorcycles and mopeds.
NOTE: Because they can run on electricity AND gasoline, hybrid vehicles must undergo emissions testing.
Your alternative fuel is safe from certain taxes. According to Wisconsin Statutes 78.82, counties, cities, towns, villages, and other subdivisions cannot charge any of the following taxes on purchasing, selling, handling, or consuming alternative fuels:
If you equip your vehicle with idle reduction equipment, Wisconsin allows you to exceed the state's axle and gross weight limits by 400 pounds (lbs.); this compensates for the extra weight of the idle reduction technology.
To qualify, you must:
Prove the weight of the idle reduction equipment with written certification.
Demonstrate that the idle reduction technology is fully functional at all times.
School districts that use biodiesel fuel to operate school busses might be able to obtain financial aid from the Wisconsin Department of Public Instruction (DPI) for the incremental cost of buying biodiesel as compared to buying petroleum diesel fuel.
NOTE: If funds are insufficient during any given fiscal year, the DPI will prorate the available funds among eligible school districts,
