What is the correct hand signal for a left turn?

Answer: B — Left arm straight out

The correct hand signal for a left turn is indicated by extending the left arm straight out from the driver's side window. This clearly communicates the intention to turn left to other drivers and pedestrians. Using this hand signal is important for safety and effective communication on the road, especially in situations where turn signals may not be visible or functional. Hands extended straight out create a clear and recognizable signal to those around you, promoting awareness and understanding of your intended movement. In contrast, the other options represent different signals, with the raised arm typically indicating a right turn, the bent arm down signaling a stop, and the right arm extended out also indicating a right turn. Understanding these signals is crucial for ensuring safe driving practices and fostering clear communication with other road users.
