What is the purpose of turn signals?

[AmyLynn]

The purpose of turn signals is to indicate to pedestrians or other vehicles the direction in which the vehicle is about to turn, either left or right. On highways, they also indicate the direction for overtaking or lane changing. When both left and right turn signals flash simultaneously, it indicates that the vehicle is in an emergency situation, alerting other vehicles to be cautious. The method to use turn signals is: 1. Push the turn signal lever to the left to activate the right turn signal; 2. Push the turn signal lever to the right to activate the left turn signal; 3. Lift the turn signal lever upwards to make the turn signals flash. The functions of turn signals are: 1. To indicate the turning direction to pedestrians or vehicles; 2. To indicate the direction for overtaking or lane changing; 3. When both left and right turn signals are lit simultaneously, it indicates that the vehicle is in an emergency situation, alerting other vehicles to be cautious.
