Emission Testing - Washington County In
  Hubertus, WI

A vehicle must be tested every two years by a certified testing site. Vehicles manufactured in an odd-numbered year are tested in even-numbered years, and vice versa. For example, a vehicle manufactured in 1999 would be tested in 2024, 2026, 2028, and so on. Conversely, a vehicle manufactured in 2002 would be tested in 2025, 2027, 2029, etc. The test must be completed before a motorist can renew the license plate, beginning in the third year following the vehicle's model year. Failure to pass the test prevents registration renewal, which in turn suspends the vehicle’s registration and makes it illegal to drive once the previous registration expires.

Vehicles that change ownership must also undergo an emissions test if they are more than five model years old, within 45 days of the ownership transfer. However, testing is not required if the vehicle passed an emissions test within 180 days before the transfer. Additionally, vehicles previously titled and registered out of state and more than five model years old must also be tested within 45 days.

Each time a test is required—either for registration or ownership transfer—the Wisconsin DOT sends a notification by mail or email. As long as you keep your information up to date with the DMV, you'll receive all necessary reminders.

When a certified site performs an emissions test, the technician connects a diagnostic tool to the vehicle’s OBD (On-Board Diagnostics) port, typically located under the dashboard on the driver's side. The system checks several details, including the vehicle's VIN, license plate, vehicle type (passenger car, van, SUV, or truck), the gross vehicle weight rating (GVWR) for heavier vehicles, and the status of various electronic monitors. The primary concern during the test is whether the check engine light is on, as this may indicate a failure to meet emissions standards.

The test is simple and usually takes less than five minutes. No appointment is needed—it’s first come, first served and is offered Monday through Friday, 8 AM to 5 PM, at our Hubertus location only.
