Why is it important to limit those who do drive on the airfield to only perimeter and access roads unless otherwise required by job function?

• A. Keeps things simple for the operator and minimizes the risk of incursions
• B. Increases throughput
• C. Reduces maintenance costs
• D. Improves fuel efficiency

Answer: (A)

On the airfield, the movement area must be tightly controlled to prevent unauthorized entry and conflicts between aircraft and vehicles. Limiting driving to the perimeter and designated access roads keeps traffic predictable and on known paths, so only trained personnel with proper clearance are on the field. This reduces confusion, simplifies monitoring, and most importantly minimizes the risk of an incursion onto runways or taxiways, where an unexpected vehicle could collide with a taxiing or takeoff/landing aircraft. If a job truly requires access beyond those roads, it can be authorized with proper procedures, but the default restriction is a key safety measure. The other options don’t address the safety and control purpose here; they’re not the primary reason for restricting airfield vehicle access.
