What is the maximum speed limit for vehicles on any airfield?

Answer: C — 15 mph

The maximum speed limit for vehicles on any airfield is 15 mph. This speed limit is established to ensure safety and control around sensitive areas where aircraft operate. At this speed, drivers have better control of their vehicles, allowing for quick reactions in unexpected situations, which is crucial in active airfield environments where both personnel and aircraft are moving. Additionally, the slower speed helps minimize the risk of accidents that could result from higher speeds, especially in areas with limited visibility or congested traffic. It’s important for airfield drivers to be aware of and adhere to these speed limits to maintain a safe operating environment.
