Which hand signal indicates a right turn?

• A. Left arm straight out for left turn.
• B. Left arm bent at 90 degrees with hand up for right turn.
• C. Left arm down with palm facing rear for stop.
• D. Right arm extended upward for stop.

Answer: (B)

The key idea is signaling turns with the arm you can see best from behind while riding. For a right turn, you bend the left arm at about a 90-degree angle and raise the hand, so the forearm points upward. This posture makes your intent clear to drivers behind you and is the standard cue for a right turn. The straight-left-arm signal is for a left turn, and the downward-left-arm signal with the palm facing rear is used to indicate stop. The right-arm signal isn’t the typical stop signal in cycling. So the left arm bent upward communicates a right turn most effectively.
