When two vehicles approach an intersection, who has right-of-way on the airfield?

• A. The vehicle with higher priority.
• B. ATC directions take precedence; otherwise yield to aircraft in proximity and follow posted signs.
• C. The fastest vehicle has priority.
• D. Vehicles yield to vehicles on the left.

Answer: (B)

ATC directions take precedence on the airfield; what ATC tells you to do overrides any other rule. If ATC isn’t giving instructions for the moment, ground vehicles must yield to aircraft that are in proximity and follow posted signs and markings. This arrangement keeps movements coordinated and safe because aircraft can be fast and have limited ability to stop once they’re near an intersection. So when ATC is guiding you, follow those commands exactly; if there’s no instruction, watch for approaching aircraft and only proceed when it’s safe and permitted by the signs.
