In case of a tool malfunction, what must be displayed at the inspection station?

In the event of a tool malfunction at an inspection station, it is essential to ensure that the public is well-informed about the station's operational status. Removing the inspection station sign effectively communicates that the station cannot perform inspections until the issue is resolved. This action prevents confusion for drivers who might otherwise assume that inspections are still being conducted.

Displaying the sign indicating closure is crucial for public safety, as it ensures that only those equipped to provide inspections are operating. It holds the inspection station accountable for maintaining proper communication with the public regarding its service capabilities. This transparency helps to avoid potential misunderstandings or safety issues that may arise from drivers expecting inspections to occur when they cannot.
