What action must be taken if an inspection station discontinues operation?

When an inspection station discontinues its operation, it is essential to return all inspection supplies to adhere to regulatory requirements. This action ensures that all materials related to vehicle inspections, such as stickers, forms, and tools that are regulated by the state, are accounted for and disposed of or returned appropriately.

Returning inspection supplies helps maintain the integrity of the inspection system by preventing unauthorized use or potential misuse of these items, which could lead to fraudulent inspections. Additionally, this process allows for the proper inventory management of such supplies, ensuring they are redirected for use in operational inspection stations.

Other options reflect alternative actions that are not mandated. For example, notifying the local media or waiting for the next renewal period does not align with the requirement for managing inspection supplies. Additionally, selling the inspection equipment is not a suitable action because it can lead to unauthorized usage of inspection materials. Therefore, the return of all inspection supplies is the correct and necessary action when discontinuing operation of an inspection station.
