Trivia: What hand signal denotes a right turn?
Left arm straight out
Left arm pointing up
Left arm pointing down
Left arm pointing right
The correct answer is Left arm pointing up
So why is this answer correct? : If turn signals aren’t functioning, drivers must signal turns using their arms. A right turn is signaled by bending the left arm with the forearm extended straight up. A left turn is signaled by a driver extending their left arm straight out the window. An arm extended down with the palm facing backward indicates slowing down or a stop.
