Vehicles require inspection every other year at the time of license plate renewal, beginning in the third year following the vehicle's model year. (For instance, model year 2007 vehicles first require an inspection in 2010.) Renewal notices indicate if an inspection is required.
In addition, vehicles more than five model years old require inspection within 45 days following registration by a new owner. The Wisconsin Department of Transportation (WisDOT) mails a letter to the new owner outlining the inspection requirements.
