Any vehicles on the runway must be clear of the runway before a departing aircraft starts takeoff. Which option correctly completes this rule?

• A. Are on the taxiway
• B. Are clear of the runway
• C. Are parked on the ramp
• D. Are in a holding pattern

Answer: (B)

Before a departing aircraft starts takeoff, the runway must be free of obstructions from any ground vehicles. This rule is about giving the aircraft an unobstructed path during the critical takeoff roll and preventing runway incursions.

The best completion states that any vehicles on the runway must be clear of the runway, meaning they have left the runway surface entirely and moved to a safe area like a taxiway or ramp with clearance. That directly satisfies the safety requirement that the takeoff path is unobstructed.

Options describing vehicles being on a taxiway, parked on the ramp, or in a holding pattern don’t express the necessary action to clear the runway, and a holding pattern is something applied to aircraft, not ground vehicles.
