If a vehicle operator holds a D permit for Company A and a D/A permit for Company B, how can these permits be utilized?

Holding a D permit for Company A means that the operator is specifically trained and authorized to operate vehicles at the airport for that company. This permit is tied directly to Company A and its policies, procedures, and safety protocols. It is important for safety and operational integrity that a vehicle operator utilizes their permits according to the specific company they are associated with.

On the other hand, the D/A permit held for Company B allows the operator to perform dual roles, but it is also restricted to Company B's operational guidelines. Therefore, the correct approach is for the operator to only use the D permit when operating for Company A to ensure compliance with Company A's standards. Using the D permit for Company B would violate the regulations and training associated with that permit, potentially leading to safety risks or other operational issues.

This focus on using the appropriate permit for the designated company helps maintain a structured and safe operating environment within the airport, thereby ensuring that all vehicle operators are adhering strictly to their specific training and authorization.
