The driver's left arm and hand are extended downward. This hand signal (left hand down) means that the driver plans to:

  1. Turn left
  2. Turn right
  3. Stop ✓
  4. Start up

Answer: C. Stop

A left arm held out and angled down means the driver plans to stop.

Why this is the answer

The manual lists the hand signals used to show turns, lane changes and stops. A left arm fully extended to the left signals a left turn, and an arm extended and bent down at the elbow signals a stop. So when you see the left arm hanging down toward the road, read it as the driver slowing to a stop, not as a turn in either direction. That is what makes the stop choice the match here.

Why the other answers are wrong

Remember it

Think of the arm as a pointer: straight out sideways is a turn, bent down toward the road is a stop, bent up is a right turn.
