What should be done with an inspection sticker if a vehicle fails inspection?

When a vehicle fails inspection, the procedure requires cutting the inspection sticker to indicate that it is no longer valid for that vehicle. Removing the month portion specifically serves to prevent any confusion about the vehicle's inspection status. This action communicates clearly that the vehicle is not compliant with safety or emissions standards until the necessary repairs have been made and a passing inspection is attained.

Other options do not fulfill the requirement for handling a failed inspection appropriately. Leaving the sticker intact would mislead others into thinking the vehicle has passed inspection, while transferring the sticker to another vehicle is not allowed, as each inspection sticker is specifically tied to a single vehicle. Not cutting the sticker fails to adequately signal its invalid status post-failure, which is critical for enforcement and safety purposes.
