What does the PRNDL gear in an automatic transmission car mean?

Automatic transmission gear positions PRNDL respectively represent: 1. P is Park; 2. R is Reverse; 3. N is Neutral; 4. D is Drive; 5. L is Low gear. Taking P gear as an example: P gear is a common position in automatic transmission models, usually located at the foremost position of the gear shift console, ahead of R gear, designed to lock the axle when the vehicle is stationary on a slope. P gear is a special neutral position that mechanically locks the transmission output shaft to secure the vehicle. The function of P gear is to act as a parking brake after stopping, preventing the vehicle from moving.
I've been driving automatic transmission cars for over a decade. The PRNDL letters on the gear shift are quite easy to remember. P stands for Park - engaging it locks the wheels to prevent rolling, perfect for parking. R is Reverse, used when backing up - step on the gas and you'll move backward. N means Neutral, where the car won't move forward or backward, sometimes used at red lights or when towing. D is Drive, the normal forward gear - engage it and you're ready to go. L stands for Low gear, ideal for hill climbing or descending when you need engine braking to control speed. Why this design? It's actually very logical - the left-to-right sequence prevents misoperation. For instance, the engine can only start in P or N gear to avoid damage. When I was younger, I once shifted incorrectly and nearly caused an accident - since then I've made it a habit to shift gears slowly. In short, this system ensures safety - just memorize it well.
