Which statement about the serpentine drill is correct?

• A. You must drive in forward and stop at each marker.
• B. You must typically drive in a straight line between markers.
• C. You must keep the vehicle centered on each marker and stop.
• D. You must drive in forward and reverse between the markers.

Answer: (D)

The serpentine drill trains you to maneuver in tight spaces by changing direction through backward movement as part of the sequence. You need to alternate between driving forward and backing up between markers, creating a zigzag path that tests steering accuracy, throttle control, and awareness of limited rear visibility. The statement describing forward and reverse movement between the markers captures this essential pattern, making it the best fit. Driving straight between markers, stopping at each marker, or only moving forward does not simulate the required back-and-forth maneuveringituated in a serpentine path.
