The letter representing the reverse gear is R. This gear enables the car to move backward. Common automatic transmissions include P (Park), N (Neutral), S (Sport), D (Drive), and R (Reverse) gears. The D gear is the most frequently used, serving as the forward drive gear. The P gear is the parking gear, which should be engaged when parking and turning off the engine. The N gear is the neutral gear, which can also be used when the vehicle is stationary. An automatic transmission allows the vehicle to automatically select the appropriate gear based on driving speed and traffic conditions. Its working principle involves using planetary gear mechanisms for gear shifting, automatically adjusting gears according to the degree of throttle pedal pressure and changes in vehicle speed. The driver only needs to control the speed by operating the accelerator pedal.

I often see novice drivers asking this question. The reverse gear is the one marked with the letter R on an automatic transmission car, where R stands for Reverse, meaning to back up. On the gear shift lever of most cars, the sequence is P-R-N-D: P is for Park, suitable for parking; R is for Reverse; N is for Neutral; D is for Drive. When reversing, you should first press the brake to ensure the car is completely stopped before shifting to R gear, otherwise, it might damage the transmission. Before shifting, it's best to look back or rely on the rearview camera to avoid hitting obstacles. Some high-end cars also incorporate automatic parking features that rely on the R gear to function. Regularly checking the transmission fluid can help prevent malfunctions.

The letter for the reverse gear is R, which is basic knowledge when learning to drive. R stands for Reverse. When driving, extra caution is needed when shifting to R gear because the rear visibility is poor, making accidents more likely. I recommend beginners develop the habit of checking the rearview mirror or using radar assistance before reversing each time. In an automatic transmission car, the gear sequence is P-R-N-D. Incorrect operations, such as shifting directly from D to R, may cause the car to jerk violently. The correct practice is to shift gears only after the car has come to a complete stop. Reversing is more challenging in bad weather, so it's important to drive slowly when using the R gear.

The reverse gear is represented by the letter R. In automatic transmission vehicles, the gear shift lever is typically marked with P, R, N, and D. R stands for Reverse. When you shift to R while driving, the car prepares to move backward. Don't rush to accelerate when reversing; first, make sure there are no people or objects behind you. Proper use of the R gear can extend the lifespan of the transmission. Some older cars may require a bit more practice to get used to it.
