PennDOT has advised of an issue with the adhesive that adheres inspection and emission stickers to windshields. The adhesive is not adhering to the windshields properly and is causing the stickers to peel away from the glass surface. The peeling stickers remain valid and do not have to be replaced. You may use small pieces of transparent tape to reattach the stickers to the windshield.
Although our officers make the best effort to verify your stickers are expired or altered before initiating a traffic stop, you still may be stopped if the officer cannot ascertain the validity of the sticker without closer inspection.
