What does automatic turn signal mean?

[VonPatrick]

Possible causes of automatic turn signals include short circuits, faulty flasher relays, excessive contact gap, and other factors. Here is an introduction to car turn signals: 1. Introduction: Turn signals are important indicator lights that are activated when a motor vehicle turns to alert vehicles and pedestrians in front, behind, and to the sides. 2. Usage: (1) When a car enters or exits a roundabout. (2) When traffic in the current lane is congested and a lane change is required. (3) When making a U-turn, the left turn signal should be activated, and the driver should observe whether there are any vehicles approaching from the front or rear before proceeding. (4) When pulling over to park, the right turn signal should be activated in advance, and the driver should observe the traffic dynamics on the right rear side before pulling over. (5) When leaving a parking spot, the left turn signal should be activated in advance, and the driver should observe the traffic dynamics on the left rear side before merging into the traffic lane.
