What is the correct hand signal for a left turn?

The correct hand signal for a left turn is to extend the left arm straight out. This gesture is universally recognized among motorists and cyclists to indicate that the rider intends to make a left turn. Extending the arm horizontally keeps it visible to vehicles and other road users, providing clear communication on the rider’s intentions.

Other options may represent different maneuvers; for instance, a left arm bent upward at the elbow commonly indicates a right turn, while a bent downward arm signals that the rider is slowing down or stopping. A right arm extended straight out is also a signal for a right turn, which can lead to confusion if misused for a left turn. Understanding these hand signals is crucial for ensuring safety on the road and for effectively communicating with other drivers.
