What should a driver do if they encounter a vehicle moving in the opposite direction?

The appropriate action when encountering a vehicle moving in the opposite direction is to slow down and prepare to yield. This approach is crucial for maintaining safety in an environment as dynamic as an airport, where vehicle movements are often unpredictable. Slowing down allows the driver to assess the situation better, ensuring that they can react appropriately based on the other vehicle's speed and distance. Yielding as necessary helps prevent potential collisions and promotes a safer airside environment.

Maintaining speed and honking the horn or trying to accelerate past would not effectively ensure safety, as it could lead to confusion or unsafe encounters with the other vehicle. Ignoring the other vehicle entirely would not be responsible and could create dangerous situations, especially in areas with high vehicle and pedestrian traffic. Therefore, reducing speed and being ready to yield is the most prudent and safe response in this scenario.
