When driving on ramps or taxiways in terminal areas, drive to the outside of which line?

• A. Inside of the white wing tip clearance line.
• B. Outside of the white wing tip clearance line.
• C. On the wing tip clearance line.
• D. Far from the wing tip clearance line.

Answer: (B)

Wingtip clearance lines are painted on ramps and taxiways to show the minimum space you must keep between your vehicle and an aircraft’s wings. You should drive to the outside of this line—the side farther from the aircraft. Staying outside provides a safe margin in case the wingtip moves slightly or gusts push air around the plane, and it helps prevent accidental contact with the wing, doors, or nearby equipment. Moving inside the line would put you too close to the aircraft, increasing the risk of a collision.
