What must every public inspection station display according to the regulations?

Every public inspection station is required to display a public inspection station sign as part of the regulations. This sign helps to clearly identify the station as a designated location for vehicle inspections, which is essential for maintaining transparency and public awareness. It lets the public know where they can go to have their vehicles inspected in compliance with state laws.

While other options might contain useful information, such as inspection results or a summary of inspection manuals, they are not required to be displayed prominently like the public inspection station sign. This specific requirement ensures that the inspection stations are easily recognizable and accessible to vehicle owners needing inspections.
