Which gear to use for overtaking with an automatic transmission?

[Ethan]

For overtaking with an automatic transmission, use the D or S gear. The method for overtaking is: 1. Turn on the left turn signal and observe the rear vehicles through the rearview mirror, paying attention to changes in the traffic ahead; 2. Sound the horn or alternately switch between high and low beams to alert the vehicle in front; 3. Downshift and accelerate, maintaining a safe distance from the vehicle being overtaken; 4. Check the rearview mirror to confirm safety, then turn on the right turn signal and return to the original lane. Precautions when overtaking include: 1. Carefully observe and make decisive judgments, obey no-overtaking traffic signs; 2. Downshift and accelerate in advance when overtaking; 3. When passing a parked vehicle, use engine braking resistance to accelerate, increase the lateral distance from the parked vehicle, and be prepared for emergency stops.
