What Do the Gear Letters on a Car Represent?

Generally, automatic transmission cars have six gear positions, arranged from top to bottom as follows: P, R, N, D, S, L. Below is an introduction to the gears on an automatic transmission car: P: Parking gear, also known as the starting gear. When the car is parked and not in use, the gear is set to this position, where the wheels are mechanically locked to prevent rolling. R: Reverse gear. As the name suggests, this gear is used when reversing the car. N: Neutral gear. This gear is used when temporarily stopping the car. D: Drive gear, also known as the forward gear. In this gear, the transmission automatically shifts between gears 1-5 based on speed and throttle conditions. S: Sport gear. When this gear is engaged, the transmission can freely shift, but the shift timing is delayed, keeping the engine at high RPMs for a period to increase the car's power. However, this gear will result in increased fuel consumption. L: Low gear. In this gear, the transmission stays in 1st gear without shifting up, which can be used in situations like climbing hills. It also provides some braking function when going downhill.
After driving for so many years, I've learned that the gear letters represent different driving states, simply put, they control how the car moves. P stands for Park, the parking gear; once parked, you must shift to this gear to lock the transmission and prevent rolling. R is Reverse, the reverse gear; use this when backing up, but be careful to check the mirrors to avoid hitting anything. N is Neutral, the neutral gear; this disconnects the transmission from power, useful for temporary stops or traffic jams to reduce engine load. D is Drive, the forward gear; this is what you use for everyday driving, as the transmission shifts intelligently. S is Sport mode, which delays shifting for higher RPMs and stronger acceleration, but consumes more fuel. L is Low gear, used for steep slopes or off-roading to prevent brake overheating. M is Manual mode, where the driver controls the shift points for a more engaging driving experience. I remember once using L gear to stabilize speed while descending a mountain road—it made things much safer. For beginners, I recommend getting familiar with the basic gears before trying S and M.
