What should be done with previous inspection stickers before affixing a new one?

Answer: B — Remove them from the windshield

When preparing to affix a new inspection sticker, it is important to remove any previous inspection stickers from the windshield. This practice ensures that there is no confusion regarding the vehicle's current inspection status. An outdated sticker can lead to misunderstandings or violations if it remains visible, as it can make it seem as though the vehicle is still within its valid inspection period. Removing old stickers allows law enforcement and inspection personnel to easily see the most recent inspection information. It also maintains the neatness and clarity of the windshield, contributing to a clearer view for the driver, which is essential for safety while operating the vehicle. Proper removal of old stickers is part of maintaining compliance with state inspection laws and practices.
