Should an automatic transmission car be shifted to P gear or turned off first when parking?

[ReedLee]

An automatic transmission car should be turned off first when parking. The following is the correct way to turn off the car: 1. First, bring the car to a complete stop. 2. Then shift the gear to N, engage the handbrake, and turn off the engine. 3. Finally, shift the gear to P. Below is an introduction to the P gear: 1. The structure of the P gear is relatively simple, with a pawl next to the gear on the output shaft. When the gear is shifted to P, the pawl engages the gear, thereby locking the output shaft. 2. If you use the P gear on a slope, you don't have to worry about the car rolling, but this doesn't mean you can park without engaging the handbrake. Engaging the handbrake is necessary, and you should only exit the car after doing so to avoid unexpected situations.
