If you are in charge of vehicles with exempt license plates know that this is not a "Clean Truck Check" testing exemption. All normal plated vehicle testing can be done up to 90 days before registration is due. Exempt plated vehicle testing dates are determined by the last number of the VIN (Vehicle Identification Number). This also applies to Vehicles that are Non-California registered vehicles but are operating in the state at any time.
