Which of the following must be followed when driving vehicles on the airport's AOA?

When driving vehicles on the airport's AOA (Airport Operations Area), adhering to specific traffic rules is crucial for ensuring safety and efficiency. These rules have been established to manage the complex interactions between ground vehicles, aircraft, and airport personnel. They encompass speed limits, right-of-way protocols, and guidelines for maneuvering around aircraft and airport facilities.

Following these traffic rules helps prevent accidents and ensures that vehicles operate safely within the congested environment of an airport. Compliance with these rules is not just a recommendation; it is a mandatory requirement designed to protect both people and property in the high-security area of the airport.

While other options may allude to practices that could be tempting to consider, they do not align with the regulatory framework that governs AOA driving. Random vehicle checks, speed limits, and driving conditions must all be respected to maintain operational integrity and safety standards at the airport.
