Welcome to Wisconsin Vehicle Inspection Program!

The Wisconsin Vehicle Inspection Program (WIVIP) is working. By having your vehicle tested, you are playing an important part in southeastern Wisconsin's successful and ongoing efforts on behalf of cleaner air and water, which creates a healthier environment for all of us.

• Along with cleaner fuels and vehicles, WIVIP has virtually eliminated the area's carbon monoxide pollution problems. However, we continue to have a problem with ground-level ozone, a major component of smog.
• WIVIP conducts over 600,000 tests for cars and light trucks in southeastern Wisconsin every year.
• WIVIP is just one part of the solution. By manufacturing cleaner cars and cleaner burning fuel, installing vapor recovery nozzles at gas stations, and implementing stronger emissions controls on utilities and industry, government and businesses are working together to make our air and water cleaner.
• Since the 1970s, industry has reduced emissions of volatile organic compounds (VOCs) by installing reduction devices, using solvents and inks with reduced VOCs, and switching to less polluting production materials.
