California DMV Driving Instructor License Practice Test

The signal used to indicate a left turn is the left turn signal. When a driver intends to make a left turn, they activate their left turn signal, which typically involves using the left blinker or indicator light on the vehicle. This signal is crucial for communicating intentions to other drivers and pedestrians, thereby enhancing safety on the road. Proper use of turn signals helps prevent accidents and ensures that all road users are aware of each other's actions, allowing for smoother traffic flow. Using hazard lights is inappropriate for signaling a left turn, as those are meant to indicate a vehicle is stopped or experiencing trouble. Activating the right turn signal obviously indicates a turn to the right and would confuse other road users when a left turn is intended. Similarly, brake lights signal that a vehicle is slowing down or stopping, which does not communicate the specific intention to turn left.
