What should be the operator's first action upon encountering a runway incursion?

The operator's first action upon encountering a runway incursion should be to immediately stop and notify the appropriate authorities. This is crucial because runway incursions can pose serious dangers to aircraft operations and can lead to catastrophic incidents. By stopping the vehicle, the operator ensures that they do not inadvertently contribute to the problem or create further hazards.

Notifying the appropriate authorities is equally important as it allows trained personnel to assess the situation and take any necessary actions to secure the runway environment. Effective communication is essential in such scenarios, as it provides immediate situational awareness to air traffic control and other relevant entities, enabling them to respond appropriately.

Rather than advancing or trying to clear the area quickly, which could worsen the situation, the emphasis is on safety and maintaining a clear understanding of the environment. This disciplined approach helps prevent escalation and ensures that all measures are taken to protect both vehicle operators and aircraft crews from the risks associated with runway incursions.
