Which two documents must an inspection mechanic carry during an inspection?

During an auto inspection in Pennsylvania, it is essential for an inspection mechanic to carry both a valid driver's license and a mechanic card. The mechanic card serves as proof that the individual is authorized and certified to conduct vehicle inspections, while the driver's license confirms their identity and legal ability to operate a vehicle. Familiarity with these requirements helps ensure that inspections are performed by qualified individuals, thus maintaining standards and safety in vehicle operations.

The other options include documents that are not necessary for conducting inspections. For instance, an insurance card is related to vehicle insurance coverage, and a registration card pertains to the vehicle that is being inspected, neither of which are required for an inspection mechanic to carry. An identification card may verify identity, but it does not specifically indicate the mechanic's qualifications like the mechanic card does.
