How early can I get my vehicle tested ahead of the license plate renewal expiration deadline?
Vehicles subject to emissions inspection may fulfill the inspection requirement up to 180 days prior to their license plate renewal date. You can determine whether your vehicle is due for inspection within the next 180 days by entering your license plate on WisDOT’s plate inquiry page. If the inquiry result page includes the statement “IM test is needed,” your vehicle’s plate renewal date falls within the next 180 days. You do not need a renewal statement in order to receive your inspection- simply visit the station registration desk, located within the office area, prior to getting in line for an inspection.
