What are the P, R, N, D gears in a car?

[CamilleLee]

In a car, P stands for Parking gear, R stands for Reverse gear, N stands for Neutral gear, and D is the most commonly used Drive gear for forward motion. Below is a partial introduction to car gears: 1. P gear: Parking gear, also used when starting the car. When the car is parked and not in use, it mechanically locks the wheels to prevent rolling. 2. N gear: Neutral gear. Used for temporary stops (such as at a red light). This gear indicates neutral, and to prevent the car from rolling on a slope, the brake must be engaged. 3. Operation steps: To shift gears in an automatic transmission car, simply push the lever to the corresponding gear. Some semi-automatic transmissions may not have as many gears; apart from P, R, and N (these three gears are essential in automatic cars), the forward gear is usually just D (as in the FAW Mazda 6), and the functions of other gears can be achieved through manual mode.
