Which gears are for forward and reverse in an automatic transmission?

"In an automatic transmission, forward and reverse gears are the D (Drive) and R (Reverse) gears, respectively. The 'R' on the gear shift stands for Reverse, which is used for backing up. The 'D' stands for Drive, indicating the forward gear. Below is an introduction to the different gears in a car: Common automatic transmission gears include L (Low), B (Brake), P (Park), R (Reverse), N (Neutral), D (Drive), and S (Sport). The L gear is the low gear, used when climbing hills to maintain high RPMs at a low gear. The B gear is the brake gear, used when driving on long downhill slopes. Engaging the B gear activates engine braking, preventing overheating of the brake pads from prolonged use of the service brake, which could lead to accidents. The P gear is the parking gear. When parking, shift into P to engage the parking brake, preventing the car from rolling. The R gear is the reverse gear, used when backing up. However, the R gear should only be engaged when the vehicle is completely stopped to avoid severe damage to the transmission. The N gear is the neutral gear, used for temporary stops, such as waiting at a traffic light. The D gear is the drive gear, used when moving forward. The S gear is the sport mode, where the transmission freely shifts based on current speed and throttle input, though with a slight delay in shifting."
When I first started driving, I noticed the convenience of automatic transmission cars. The forward gear is the D (Drive) gear, which allows smooth driving once engaged; reversing is done with the R (Reverse) gear, specifically designed for backing up. It's crucial to switch gears only after the vehicle has come to a complete stop to prevent damage to the transmission system. Many beginners might confuse it with the P (Park) or N (Neutral) gears, but remembering D and R covers most daily needs. In city driving, most of the time is spent in D gear, easily handling traffic lights or highways; however, when encountering steep slopes, some cars have additional gears like L (Low) or S (Sport) for better control. Developing a habit of checking the dashboard before starting the car can prevent accidents—this is my years of driving experience.
