Which arm signal indicates stop?

• A. Arm straight out
• B. Arm bent upwards at elbow
• C. Arm raised to the side
• D. Arm bent downwards at elbow

Answer: (D)

When you’re signaling with your arm, you’re using a universal set of cues to let others know what you’re about to do. For stopping, the left arm is bent downward at the elbow, with the forearm angled toward the ground. This downward bend is distinct from the left turn (arm straight out) and the right turn (arm bent upward). An arm raised to the side isn’t a standard signal for stopping, so it doesn’t clearly communicate your intention. Using the downward bend communicates to drivers behind you that you intend to slow or stop.
