Is it necessary to press the brake when shifting gears in an automatic transmission car?
3 Answers
Automatic transmission cars require pressing the brake when shifting gears. Generally, these cars have gear positions such as P (Park), R (Reverse), N (Neutral), and D (Drive). The reason for pressing the brake during gear shifting is to prevent misoperation and ensure safety. Regardless of whether the gears can be freely switched between each other, shifting gears while the vehicle is in motion is unsafe and can also cause some damage to the car's transmission. Some automatic transmission models do not require pressing the brake when shifting gears because many models are designed with an unlock button that prevents shifting from P to other gear positions without pressing the brake. Some vehicles even prohibit shifting from P to other gear positions if the accelerator is pressed to a certain depth, even when the brake is pressed. For safety reasons, it is recommended to press the brake when performing gear-shifting operations in automatic transmission vehicles, just as one should develop the habit of pressing the clutch when starting a manual transmission car.
I remember when I first learned to drive, the instructor repeatedly emphasized that shifting gears in an automatic transmission must be done while pressing the brake pedal, calling it a fundamental skill for survival. After driving for over a decade, I’ve concluded that this rule is absolutely essential. This is because vehicles are designed with a safety mechanism—for example, when in Park (P) or Neutral (N), if you don’t press the brake, the transmission inhibitor switch locks the gear to prevent shifting, avoiding accidental rolling. Once, on a slope, I tried to shift without pressing the brake, and the car almost rolled backward, giving me a cold sweat. Developing this habit makes driving much safer, especially when parking or at traffic lights. Even with newer keyless-start cars, you must press the brake to shift out of Park (P), or the gear lever won’t budge. In short, safety comes first—new drivers should practice until it becomes second nature.
I just got my driver's license last year. When I was learning to drive an automatic transmission car, my instructor always reminded me to press the brake when shifting gears. He explained that this is not only a rule but also a necessary step to prevent accidents, because the transmission system of an automatic car locks when the brake is not pressed, preventing the car from moving suddenly. At first, I didn't pay much attention and thought I could skip this step, but once during traffic congestion, I shifted gears without pressing the brake firmly, and the car shook violently and almost hit the car in front. Later, I also read in the driving manual that this practice helps avoid tire slippage or rolling accidents. I suggest new drivers develop the habit of pressing the brake every time they shift gears for a smoother drive. When waiting at a red light, don't rush—press the brake firmly before shifting gears.
