What should be done if there is dirt or moisture on the area where the inspection certificate will be applied?

Cleaning the area before applying the inspection certificate is essential to ensure that the sticker adheres properly and remains intact. Dirt or moisture can prevent the adhesive from making a solid bond to the surface, leading to peeling or loss of the sticker over time. By cleaning the area, you remove any contaminants that could interfere with adhesion, allowing the sticker to affix securely. This practice not only maintains the integrity of the inspection certificate but also ensures that it can be easily read and verified by law enforcement or inspection personnel.

Using a wet application method, ignoring the dirt, or applying the sticker without cleaning would likely result in a failure of the sticker to remain in place and could lead to non-compliance with inspection regulations. Proper adherence of the inspection certificate is vital for a vehicle's registration and legal roadworthiness.
