What does P mean inside a car?

The P in a car stands for the parking gear, which is the most common gear in automatic transmission models. It is usually located at the frontmost position of the gear shift console, ahead of the R gear. It is mainly used when you park the car and don't need to move it. When the gear is in this position, the wheels are mechanically locked to prevent rolling. Below are the main functions of the P gear: 1. Parking on flat ground: The P gear is both a neutral gear and has a braking mechanism, so engaging the P gear directly serves the purpose of parking. When temporarily stopping on a level road, engaging the P gear puts the car's transmission in neutral operation, completely interrupting the power transmission from the engine to the output shaft. The driver does not need to turn off the running engine during short waiting periods. 2. Parking on slopes: The core function of the P gear is to achieve long-term and safe parking on slopes for automatic transmission cars, which is also the key role of the P gear in the entire automatic transmission car industry. When the vehicle is parked on flat ground, both automatic and manual transmission cars only need to use the handbrake to keep the car stable on the road for a long time.
I remember when I first started learning to drive, I couldn't figure out what that 'P' in the car meant. It wasn't until I had a minor accident that I finally understood. That time, I parked on a slope, turned off the engine without shifting to 'P', and the car slightly slid, almost hitting a tree by the roadside. From then on, I remembered: 'P' stands for Park, specifically for automatic transmission cars. Before you turn off the engine, you must shift to 'P', so a locking mechanism in the transmission will engage the wheels, preventing the car from rolling. Using the handbrake together is even safer, especially on slopes or uneven ground. Normally, there are other gears like D, R, N, etc., but 'P' is the most crucial safety step. Make it a habit: shift to 'P' before turning off the engine to avoid the risk of rolling. Regular transmission maintenance also helps keep it in good condition for the long term.
