Airfield Driving Course Practice Exam

The correct speed limit for special purpose vehicles on the airfield is 10 mph. This limit is established to ensure the safety of both the vehicles and the airfield operations. Special purpose vehicles, such as snow plows, fuel trucks, and other maintenance vehicles, operate in areas where aircraft are moving, and are often in close proximity to active runways and taxiways.

Maintaining a speed of 10 mph allows these vehicles to navigate safely while minimizing the risk of accidents or collisions with aircraft or personnel. This speed limit is designed to balance the need for operational efficiency with the imperative of maintaining a safe environment on the airfield.

Other speed limits, such as 5 mph or higher limits like 15 mph and 20 mph, would either be too restrictive or too high for the operational safety required in these areas, making 10 mph the appropriate choice for the conditions encountered in airfield operations.
