The turn signals of a car are usually located on the left and right sides of the front and rear of the vehicle. Some models also feature additional turn signals above or below the side mirrors to enhance visibility. The control switch inside the car is on the lever at the lower left of the steering wheel, operating on the principle of "up for right, down for left"-pushing up activates the right turn signal, while pulling down activates the left turn signal. When driving, turn signals should be activated approximately 10 seconds in advance to allow following vehicles sufficient time to react, but not excessively early to avoid confusion. For parking on the right side, the right turn signal should be engaged; when pulling away, the left turn signal should be used. Modern vehicles are equipped with a "three-flash" function: a light tap of the lever triggers three automatic flashes, suitable for lane changes or overtaking manoeuvres. The standardized positioning and operation of turn signals ensure clear communication to other road users, effectively reducing accident risks and serving as a critical component of safe driving.
