Louisiana Class D Chauffeur's License Practice Test

The proper hand signal to indicate a left turn is to extend your left arm straight out. This signal is universally recognized and allows other road users, including drivers and cyclists, to understand your intentions clearly. Hand signals are essential for communication on the road, especially in situations where vehicle signals may not be visible or functional. Extending the left arm outwards directly communicates that you plan to make a turn to the left, making it clear to others what movement you are about to make. The other options represent different signals: the right arm extended straight out indicates a right turn, raising the left arm upward signals a stop, and lowering the left arm downward is typically used to signify a slowdown or stop as well. Understanding and using proper hand signals is crucial for road safety and effective communication while driving.
