How must a driver respond to a "Stop" sign in restricted areas?

When a driver approaches a "Stop" sign in restricted areas, the appropriate response is to come to a complete stop and yield to any oncoming traffic or pedestrians. This action is critical for maintaining safety in high-security areas such as airports where the potential for interaction with aircraft, personnel, and pedestrians is significant.

Stopping completely ensures that the driver has a clear view of their surroundings and can assess whether it is safe to proceed. Yielding to oncoming traffic or pedestrians is vital as it helps to prevent accidents and ensures compliance with traffic regulations. This rule is particularly emphasized in restricted areas, where safety protocols are stringent to protect both individuals and operational aircraft.

Other options might suggest a less cautious approach, such as proceeding without stopping or ignoring the sign if the area appears clear. However, these could lead to hazardous situations, especially in environments where unpredictability is higher due to the presence of moving aircraft and personnel.
