What is the airfield speed limit when visibility is 300 meters (900 feet) or less?

Answer: B — 15 MPH

In situations where visibility is 300 meters (900 feet) or less, the established airfield speed limit is specifically set to 15 MPH. This speed limit is implemented to enhance safety and reduce the risk of accidents in low visibility conditions. When visibility is compromised, drivers may have difficulty spotting other vehicles, personnel, or potential hazards, making it critical to limit speed. Maintaining a lower speed allows for quicker reaction times and better control of the vehicle in unexpected situations. Establishing a speed limit of 15 MPH under these circumstances balances the need for efficient movement around the airfield while prioritizing safety for both drivers and personnel on the ground.
