Question: 1 / 400

What is the proper arm signal for a left turn?

Left arm pointing straight out

The proper arm signal for a left turn is when the left arm is extended straight out. This signal is universally recognized and clearly indicates to other road users that you intend to make a left turn. Using this arm position not only communicates your intention effectively to drivers and cyclists nearby, but it also complies with traffic laws that require drivers to signal their maneuvers. Proper signaling is essential for road safety, as it helps prevent misunderstandings and potential collisions at intersections.

In comparison, the other arm positions have specific meanings: a left arm bent at a 90-degree angle upward indicates a right turn, while a left arm pointing down signals a stop. The right arm pointing straight out, though sometimes used to indicate a turn in specific contexts, does not convey a left turn and could lead to confusion if used improperly.
