When should an inspector have their Inspection card on hand?

An inspector should always have their Inspection card on hand whenever they are performing an inspection. This practice is essential as it verifies the inspector's credentials and authority to conduct the inspection. Having the card readily available ensures compliance with regulations and fosters trust with the vehicle owner or operator undergoing the inspection. It also allows inspectors to easily present their qualifications and the legitimacy of the inspection process at any moment, enhancing professionalism and accountability.

The other choices present scenarios that limit the use of the Inspection card to specific situations, which does not reflect the comprehensive nature of the inspector's responsibilities. In Pennsylvania, the inspectors’ duties require them to be prepared for any potential inspection at any time, making it crucial for them to have their card accessible consistently, not just during specific events like scheduled inspections, audits, or only when requested by a customer.
