Which signal involves extending one arm at 45 degrees up and the other at 45 degrees down, with palms facing forward?

Which signal involves extending one arm at 45 degrees up and the other at 45 degrees down, with palms facing forward?

• A. Extend one arm at 45 degrees up and one 45 degrees down, palms to the front, lower arms indicate direction of movement.
• B. Extend both arms forward, large vertical circles.
• C. Raise either arm to the vertical position. Drop the arm to the rear, describing complete circles in a vertical plane parallel to the body.
• D. Extend both arms downward and to the side, arms at 45 below horizontal plane, palms front.

Answer: (A)

This question tests recognition of a two-arm signaling posture used to convey movement direction. Extending one arm at 45 degrees up and the other at 45 degrees down, with both palms facing forward, creates a clear, opposing angle silhouette that observers can read at a distance. The key detail is that the lower arm’s position indicates the direction of movement—this specific configuration is the standard signal for guiding movement in a particular direction. The other options describe different arm positions and motions that correspond to other signals, so they don’t match this exact posture.
