Should I turn on the left turn signal when overtaking?

[SanStella]

When overtaking, you should turn on the left turn signal and overtake from the left side of the vehicle in front. After overtaking and maintaining a necessary safe distance from the overtaken vehicle, turn on the right turn signal and return to the original lane. According to Article 47 of the Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China, when overtaking, motor vehicles should turn on the left turn signal in advance, switch between high and low beams, or sound the horn. On roads without a central dividing line or with only one motor vehicle lane in the same direction, if the vehicle in front receives an overtaking signal from the vehicle behind, it should reduce speed and move to the right to give way when conditions permit. The vehicle behind should overtake from the left side of the vehicle in front after confirming there is sufficient safe distance, and after maintaining a necessary safe distance from the overtaken vehicle, turn on the right turn signal and return to the original lane.
