What factor is NOT considered part of the airfield driving performance?

In the context of airfield driving performance, the critical factors include adhering to set speed limits, obeying stop signs, and following right-of-way rules. These elements are essential in ensuring safe and efficient vehicle operation on the airfield, thereby preventing accidents and facilitating the smooth flow of ground traffic.

Displaying road signs is not directly considered part of an individual driver's performance. Instead, this task typically falls under the responsibilities of airfield management and safety personnel, who are tasked with ensuring that appropriate signage is placed and maintained throughout the airfield. Therefore, while road signs are vital for providing guidance and information to drivers, their display does not pertain to the personal driving actions monitored in airfield driving assessments. Understanding this distinction helps clarify the focus of performance evaluations, which primarily assess the actions of the driver rather than the infrastructure in place.
