one thing to note...With a vehicle, you have to have windshield wipers, but you do not have to have a wind shield.Without a windshield (i.e. a jeep you would take hunting) you keep the sticker in the glove box.You are much more likely to get pulled over, but it is what it is.With a motorcycle, if you do not have the plate in the back, you must have the sticker somewhere else...This is just what I learned when I was getting certified as a state inspector....
20.04 Certificate Mounting Procedures for Motorcycles, Motor-Driven Cycles, and Mopeds1. On the Vehicle (Optional). Punch the month of issuance and year of expiration. Remove the certificate’s back paper and attach the certificate face up on the vehicle’s rear fender or any other visible location on the rear near its license plate.Place the certificate in place and apply firmly. OR2. Backing Plate (Optional - to be furnished by cycle owner). Punch the month of issuance and year of expiration. Remove the certificate’s back paper and attach the certificate face up on the backing plate which is mounted on the cycle near the license plate for this purpose. Place the certificate in place and apply firmly.3. Other Provisions - Motorcycles, Motor-Driven Cycles, and Mopeds. Reject the vehicle if no fender or optional location is available for applying the inspection certificate.
The side cover in skippy75's case is considered a "backing plate" as is anything else we mount for the purpose of placing the inspection sticker.
note to self: now that you have forgotten about getting the inspection sticker for two years now, put it on the "to do" list before the next two years pass.
