Which gear should an automatic car be in when waiting at a red light?

[LeAdelyn]

Which gear an automatic car should be in when waiting at a red light depends on different situations: 1. If the waiting time is more than 40 seconds, shift to N gear; 2. If it is less than 40 seconds, stay in D gear. In an automatic car, the driver does not need to manually shift gears; the vehicle will automatically select the appropriate gear based on the driving speed and traffic conditions. There are six gear positions in an automatic car, from top to bottom: P, R, N, D, S, and L. The correct method to start an automatic car is: 1. Move the gear selector to the intended driving position and then press the accelerator; 2. Do not press the accelerator abruptly; press it slowly.
