How can drivers ensure they are following airport pedestrian traffic rules?

Answer: C — By obeying posted signs and signals

Obeying posted signs and signals is crucial for drivers to ensure they follow airport pedestrian traffic rules. Airports are complex environments with a high volume of pedestrian and vehicle traffic, which makes clear communication through signage and signals essential for safety and efficiency. These signs and signals provide specific information regarding speed limits, restricted areas, pedestrian crossings, and other important rules that respect the shared airspace between pedestrians and vehicles. Adhering to these guidelines not only helps prevent accidents but also promotes a harmonious flow of traffic within the airport premises. Other options do not promote safety or compliance with the established traffic rules. For example, simply watching for vehicles may lead to oversights regarding pedestrians or traffic signals. Relying on instinct can result in unsafe decisions due to the unpredictable nature of airport environments. Checking weather conditions, while important for safe driving, does not directly relate to adhering to pedestrian traffic rules or airport regulations. Therefore, following posted signs and signals is the most effective way for drivers to navigate safely in airports.
