If a ground motor vehicle operator encounters a taxiway, what must they do before crossing?

Observing surrounding vehicles is crucial for the safety of both the vehicle operator and the aircraft using the taxiway. Before crossing a taxiway, it's essential for ground motor vehicle operators to ensure that no aircraft are approaching or taxiing on that path. This awareness helps to prevent potential collisions and maintain the orderly flow of ground traffic at the airport.

In an airport environment, where multiple types of vehicles and aircraft operate in close proximity, this vigilant observation allows operators to gauge the appropriate timing for crossing and respond accordingly to any potential hazards. Awareness of one’s surroundings is a critical safety measure that helps everyone involved in airport operations ensure a safe and efficient environment.
