Answer options
ALeft arm out the window, with the hand pointing up
BLeft arm out the window, with the hand pointing down Correct
CLeft arm out the window, held straight and level
Why
To signal that you are stopping or slowing down, put your left arm out of the window and angle it downward so the hand points at the ground. In the picture, an arm held straight out means a left turn and an arm bent upward means a right turn.
