Which statement about the serpentine exercise is true?

• A. You must drive in forward motion only between the markers.
• B. You must reverse before crossing each marker.
• C. You must drive around the markers without reversing.
• D. You must drive in both forward and in reverse between the markers.

Answer: (D)

The serpentine exercise tests precise vehicle control in a tight, weaving path. To navigate the space between each pair of markers, you must use both forward and reverse movements. Moving forward alone won’t let you position the vehicle correctly for the next leg, and reversing alone wouldn’t carry you through the forward segments. By alternating directions, you can align accurately between markers and maintain the required spacing and turning radii as you weave from one gap to the next. This combination of forward and reverse maneuvers is what makes the serpentine doable and safe in a confined course.
