What happens to an inspector/mechanic whose permit has been suspended?

The answer is correct because when an inspector or mechanic's permit has been suspended, they are not automatically allowed to resume their duties or reapply without further process. The requirement to pass a reexamination for reinstatement ensures that the individual demonstrates their competency and knowledge before being allowed to conduct inspections again. This process is designed to maintain high standards of safety and professionalism in vehicle inspections, as it confirms that the inspector has addressed the issues that led to the suspension and is fit to carry out their responsibilities.

Other options suggest either immediate reapplication without conditions, automatic renewal, or a lifelong ban, none of which align with the established procedures for dealing with permit suspensions. The goal is to protect public safety by ensuring that only qualified individuals can perform vehicle inspections after a suspension.
