What happens to unauthorized vehicles in restricted areas?

In restricted areas of an airport, unauthorized vehicles pose significant safety and security risks. The appropriate action taken is to immediately tow these vehicles away. This ensures that the restricted zones remain clear and secure for authorized personnel and operations. By removing unauthorized vehicles without delay, airport authorities can prevent any potential disruptions or security breaches that could arise from their presence.

This immediate towing action emphasizes the importance of maintaining strict access control within airport operations, thereby prioritizing safety and compliance with regulations. The other actions listed, such as issuing warnings or allowing temporary stays, do not adequately address the security protocols required in these sensitive areas.
