Should an automatic transmission car be parked in P or N?

Automatic transmission cars should be parked in both P and N gears, just in a specific sequence. When parking an automatic transmission car, first press the foot brake to stop the vehicle, then shift the gear from D to N, engage the handbrake, turn off the engine, press the foot brake again, shift from N to P, release the foot brake, and finally turn off the power and remove the key. Automatic transmission generally refers to the car's automatic gear-shifting mechanism, where the control system of the automatic transmission selects the appropriate gear based on the engine's speed and load during driving, replacing the driver's subjective judgment and gear-shifting operations. Typically, an automatic transmission car has six gear positions, from top to bottom: P, R, N, D, S, L.
I've been driving automatic transmission cars for over ten years and have developed the habit of shifting into P (Park) when parking, because the P position locks the transmission to prevent the vehicle from rolling. Like that time at the supermarket parking lot on a slope, my friend tried parking in N (Neutral), and the car rolled, nearly hitting something. Since then, I've emphasized safety first. For short stops like at traffic lights, you can use N or keep it in D (Drive), but when turning off the engine or parking for a long time, you must shift into P and also engage the handbrake for double security. The P gear in automatic transmissions is designed precisely for such scenarios to avoid unnecessary wear or accidents. Developing this habit in daily driving can extend the vehicle's lifespan and reduce maintenance hassles.
As an automotive technology enthusiast, I find shifting to P (Park) gear the most reliable when parking. The P gear mechanism locks the transmission output shaft, ensuring the vehicle remains stationary without movement. In contrast, N (Neutral) gear is simply a free gear, suitable for short waits like at traffic lights but does not provide parking functionality. Using N gear for long-term parking poses high risks, such as potential rolling on slopes or transmission damage. I recommend always shifting to P gear when turning off the engine, while also engaging the handbrake on flat ground for added safety. Checking the vehicle manual will provide guidance, as many newer models integrate electronic parking functions that automatically optimize protection. Developing this operational habit can enhance the driving experience.
When I was learning automatic transmission, the instructor repeatedly emphasized parking in P gear. Simply put, P gear locks the car to prevent movement and must be used when turning off the engine to park; N gear is neutral for short stops like waiting at a red light. Don't mix them up to avoid potential rolling when parked in N gear for long periods. To ensure safety, make it a habit to use P gear and engage the handbrake for extra security.
