According to safety protocols, what is the primary route vehicles should use to yield to taxiing aircraft?

Using the most direct route via a paved surface to yield to taxiing aircraft is essential for safety. Paved surfaces are designed to support vehicle weight and provide better traction and visibility, which are crucial when navigating around active flight operations. This choice ensures that vehicles can quickly and safely clear the path for taxiing aircraft, minimizing potential hazards and disruptions to air traffic.

In an airfield environment, the priority is to maintain clear and safe routes for aircraft, and utilizing paved surfaces enhances the capability to react swiftly and efficiently to any ongoing aircraft movements. Other options such as indirect routes via dirt paths, narrow paths through hangars, or any available route regardless of surface conditions may introduce safety risks, such as unstable ground, limited visibility, or potential obstacles that could impede either vehicle or aircraft movements. Adhering to the protocol of using direct and paved routes significantly reduces these risks and upholds overall airfield safety.
