What should a driver do when encountering a malfunctioning traffic signal in restricted areas?

When a driver encounters a malfunctioning traffic signal in restricted areas, they should treat it like a stop sign and proceed with caution while informing security. This approach ensures safety for all motorists and pedestrians. Treating the situation as a stop sign means the driver must come to a complete stop, assess the intersection for any other vehicles or pedestrians, and then proceed only when it is safe to do so. Informing security is also crucial, especially in restricted areas, as they can assess the malfunction and manage traffic to prevent accidents.

This method prioritizes safety and situational awareness, which is essential in high-security zones like those around airports. The other responses suggest unsafe driving behaviors, such as continuing without stopping or accelerating through the intersection, which could lead to accidents and compromise safety protocols. Ignoring the signal entirely can also create dangerous situations, even in the absence of other vehicles, as conditions may change unexpectedly. Adopting a cautious and communicative approach aligns with the protocols necessary for maintaining safety in restricted areas.
