A driver extends the left arm straight out horizontally. What does this hand signal mean?
Correct answer: The driver intends to turn left.
Why
The left arm extended straight out signals a left turn. Check traffic and make the turn only when safe; the signal does not give priority. Hand signals may be needed if the vehicle’s turn signals cannot be used.
