Where must vehicles display official airport credentials?

Vehicles must display official airport credentials in a visible location, typically on the dashboard, to ensure that they can be easily identified by airport security personnel and other officials. This visibility is crucial for maintaining security protocols within the airport environment, where unauthorized access can pose significant risks. Credentials placed in a visible area allow for quick verification of the vehicle's legitimacy and the identity of its operator, facilitating smoother operations within airport premises.

When credentials are displayed on the dashboard, it minimizes any delays and enhances safety measures, as security personnel do not need to approach vehicles to check for compliance. This accessibility helps in keeping the airport secure while allowing authorized personnel to navigate the area without hindrance.
