A steering angle sensor is configured to detect a steering angle of a vehicle. A controller is configured to control the turn signal switch to turn on and off a turn signal lamp according to an operation mode and to turn off the turn signal lamp in at least one of a case in which the steering angle, which returns in a reverse direction to a course change direction detected by the steering angle sensor, reaches a preset angle and a case in which an operation time of the turn signal switch exceeds a preset time.
