When should pilots be especially cautious of intervening vehicles on the taxiway?

Pilots should be especially cautious of intervening vehicles on the taxiway at taxiway/runway intersections due to the high volume of traffic and potential for conflicting movements in that area. These intersections are critical points where aircraft are most likely to encounter vehicles, including ground services, maintenance crews, and other aircraft. The complexity of these areas, combined with the potential for limited visibility and situational awareness, necessitates heightened vigilance from pilots.

At taxiway/runway intersections, the chance of miscommunication and misunderstanding between ground vehicles and aircraft increases, which can lead to unsafe situations. Therefore, maintaining situational awareness and following proper communication protocols is essential for preventing accidents in these high-traffic zones.

While other conditions, such as wet taxiways or nighttime operations, can increase risks, the specific dynamics of taxiway/runway intersections make this the most critical area for pilot caution regarding intervening vehicles.
