Rapid Screen: Payment and Notifications

If your vehicle has passed RapidScreen’s emissions qualifications, you’ll receive a notification in the mail that reads, “Passed roadside emissions” on your registration renewal card. You can accept your car’s clean bill of health and save yourself a trip to an emissions testing facility by simply paying the emissions fee along with your registration renewal fee. (Your vehicle registration will be your proof of emissions compliance.)

Testing Deadlines

To meet the qualifications for RapidScreen, state regulation requires that your vehicle record two clean readings within a ten-month window. That window includes each of the twelve months prior to your registration renewal month, with the exception of the final two months. For example, if your renewal month is June, the cutoff date for passing your emissions test via RapidScreen is April 1. (RapidScreen readings obtained during your “off” year, in which you may renew your vehicle registration without obtaining an emissions test, do not qualify.)
