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

An automatic transmission car should be parked in P gear. The correct methods for using an automatic transmission are as follows: 1. P – Parking gear. When parking and not in use, the gear should be in this position, where the wheels are mechanically locked to prevent rolling. 2. R – Reverse gear. Used when reversing. 3. N – Neutral gear. Used for temporary stops (e.g., at a red light). 4. D – Drive gear, also known as the forward gear. Used when moving forward. 5. L – Low gear. Used when going downhill. 6. OD – Overdrive gear. Used for high-speed driving.
I think this is a pretty common issue. From my driving experience, you must engage the P (Park) gear when parking because it's specifically designed for parking and locks the transmission to prevent the car from rolling. In contrast, the N (Neutral) gear is just a free gear without any locking mechanism. If you park on a slope with only the N gear engaged, the car might slide away, which is a significant risk. My usual habit is to first apply the handbrake to stabilize the car before shifting into P gear, providing double security. Also, the engine should be turned off only when in P gear to avoid damaging the transmission. Sometimes, at red lights or during brief stops, I shift to N gear to save a bit of fuel, but that's just for a few minutes. For actual parking or long stops, you must switch back to P gear. Remembering this can protect your vehicle's lifespan and ensure driving safety—forming good habits is much simpler than fixing problems later.
From my daily driving perspective, putting the car in Park (P) is essential because it firmly locks the gears, while Neutral (N) doesn't have this function. I once forgot to shift gears in a supermarket parking lot and only left it in N, causing the car to slowly slide toward the curb—quite a scare. Using P along with the handbrake is safest, especially on slopes. For short stops while waiting, N can reduce fuel consumption, but when parking and leaving the car, always shift to P without hesitation. I also pay attention to the transmission warning light—if it's in P but the engine is still running, the light might come on as a reminder. This small detail helps prevent unexpected issues. In short, P is designed for your safety—don't cut corners.
As a car enthusiast, I always prefer to park in P (Park) gear. The P gear locks the transmission output shaft to prevent rolling, while N (Neutral) gear only cuts off power and is useless when parking. If you only shift to N gear, such as when turning off the engine in a garage, the car may move and hit a wall. I recommend combining it with an electronic parking brake or traditional handbrake for added safety. Also, check if the parking mechanism is worn, and regular transmission maintenance can extend its lifespan. The parking procedure is simple: brake, shift to P, engage the handbrake, and turn off the engine. This sequence must not be messed up to protect mechanical components.
