What are the acceptable forms of vehicle identification during a Class D inspection?

The correct choice highlights the importance of the vehicle's registration and the VIN as essential forms of identification during a Class D inspection. The vehicle registration serves as the primary document that confirms the vehicle's legal status on the road, indicating that it has met all legal requirements for ownership and operational compliance according to state regulations.

The VIN, which is a unique code assigned to each vehicle, provides critical information about the vehicle's make, model, and year. It helps inspectors verify the identity of the vehicle against official records, ensuring that the vehicle being inspected is the same one listed in the registration documents. This helps to prevent fraud and ensures proper tracking of the vehicle's history.

Other options such as ownership history may vary and are less commonly used in standard inspections since they do not provide direct confirmation of current legal status. Insurance paperwork, while important for general driving legality, is not typically required for identification during the formal inspection process, which focuses primarily on registration and VIN verification.
