What action is required if runway hold lights are illuminated?

When runway hold lights are illuminated, they signal that the runway is not safe for crossing. It is essential to wait for explicit instructions from air traffic control (ATC) to cross. This protocol ensures that the runway is clear and that there are no other aircraft taking off or landing on the runway at that time. Following ATC's guidance is critical for maintaining safety and order in airside operations.

The hold lights serve as a visual indication to alert pilots and vehicle operators that they must not proceed onto the runway. This safety measure helps to prevent potential collisions and maintains the integrity of airfield operations.

Following ATC's instructions is necessary to ensure that all parties are aware of the situation and can act accordingly. This emphasizes the importance of communication in aviation operations and highlights the role of ATC in managing runway activity.
