Which turn signal goes left?

In car driving, the left turn signal is used to indicate that the vehicle is about to move or turn left. According to traffic regulations and driving standards, the left turn signal should be used in the following scenarios: making a left turn, changing lanes to the left, before initiating an overtaking manoeuvre, when departing from a parking spot, and when executing a U-turn. For instance, when a vehicle needs to turn left at an intersection, the left turn signal should be activated 30 to 100 meters prior to the turn, enabling following and oncoming vehicles to promptly recognize your intended manoeuvre. During overtaking, the left turn signal should first be engaged to alert the preceding vehicle; upon completing the overtake, the right turn signal must be activated to indicate the return to the original lane. Drivers should cultivate the habit of activating turn signals at least 3 seconds in advance and ensure their proper functioning, with particular attention to their warning function under low-visibility conditions such as rain or fog.
