What is the correct way to use lights when overtaking?

[ElliottRose]

When overtaking, the correct way to use lights is: 1. Turn on the left turn signal and sound the horn: Before overtaking, increase your speed and approach the left side of the vehicle being overtaken, maintaining a following distance of no more than 2000mm, then turn on the left turn signal and sound the horn. 2. Turn on the right turn signal and return to the original lane: After confirming that the vehicle ahead has yielded or signaled to allow overtaking, steer slightly to the left, maintain a safe lateral distance from the vehicle being overtaken, accelerate past it from the left side, continue driving straight after overtaking, and when you have achieved a safe distance of 20 to 50 meters beyond the overtaken vehicle, turn on the right turn signal and return to the original lane.
