What is the first action you should take if you see a stop sign while driving on the airside?

When encountering a stop sign while driving on the airside, the first action you should take is to stop completely and check for other vehicles. This behavior is crucial because stop signs are in place to ensure safety in areas where there may be high levels of traffic, including aircraft, other vehicles, and personnel. By stopping completely, you give yourself the opportunity to assess the situation thoroughly.

Looking around after stopping allows you to ensure that the path is clear and that there are no other vehicles or aircraft approaching, which is vital for maintaining safety on the airside. This action not only complies with traffic regulations but also prevents accidents and enhances situational awareness in a busy environment.

Other options might not prioritize safety in the same way. For instance, merely slowing down may not be sufficient, as it does not guarantee that you are adequately aware of your surroundings. Proceeding without ensuring that the area is clear poses a significant risk, while calling air traffic control is unnecessary for this specific situation and would divert attention away from immediate safety responsibilities.
