In Wisconsin, emissions testing is required for gasoline-powered vehicles that are from model year 1996 or newer and are up to 25 years old.
Wisconsin requires eligible vehicles to undergo emissions testing every two years as part of the registration renewal process.
In some cases, if a vehicle fails the emissions test and the owner has spent a specified amount on repairs, they may be eligible for a waiver.
Vehicle owners can use the Wisconsin DMV website to check if their vehicle is due for an emissions test based on their registration renewal.
In Wisconsin, emissions testing is provided at no cost to the vehicle owner.
