An arm extended away from the body and moving up and down. What does this signal indicate?

• A. Turn left
• B. Turn right
• C. Reversing
• D. Intention to slow down or stop

Answer: (D)

Communicating your intended speed and stop using a hand signal is common for cyclists and drivers without working indicators. An arm extended to the side and moved up and down is the signal that you intend to slow down or stop. The up-and-down motion is a clear cue to others behind you that you’re reducing speed or coming to a halt, which helps prevent surprises on the road. This is distinct from turning signals—left turn is the arm straight out to the left, right turn is the arm bent with the hand pointing upward—and reversing isn’t indicated by this motion.
