What should vehicles do when a helicopter is approaching?

• A. Proceed slowly
• B. Maintain speed on approach
• C. Remain clear
• D. Move to the helicopter

Answer: (C)

When a helicopter is approaching, keep well clear of its approach and landing path. The rotor blades spin rapidly and create strong downwash, which can strike people or vehicles and fling debris. Moving toward the helicopter or trying to guide it can put you in the rotor arc or in its downwash zone, so the safest action is to stop and stay out of the approach area until the helicopter has landed or cleared the area and you have the proper clearance to proceed. Maintain a wide berth and avoid any actions that could block or interfere with the helicopter.
