Do You Need to Press the Accelerator When Reversing an Automatic Car?

When reversing an automatic car, there is no need to press the accelerator; just manage the brake properly. However, not all automatic cars will move on their own when shifted into reverse gear—some may require a bit of throttle. The specific reasons are as follows: 1. When reversing, the driver's attention is highly focused, and accidentally pressing the accelerator too hard can easily lead to a traffic accident. Therefore, it is sufficient to control the speed using the brake. 2. The torque in reverse gear is slightly less than that in first gear. If you shift into reverse without pressing the accelerator, the car might not move. 3. Rust on the brake discs due to water contact. This increases the rolling resistance of the wheels, so pressing the accelerator may be necessary to move when in reverse gear. 4. Dirty transmission fluid or slipping clutch plates. Automatic cars use a torque converter to transfer engine power to the transmission, while dual-clutch transmissions use friction plates similar to manual transmissions to transfer power. The principle of a torque converter is akin to one fan blowing air at another, except the medium is transmission fluid instead of air. If the transmission fluid is too dirty or deteriorated, it cannot function properly, causing the car to fail to move when shifted into reverse gear.
When reversing, if the car is on flat ground, you can slowly move without pressing the accelerator after shifting into reverse gear, because an automatic transmission car can provide power to move backward at idle speed. I usually don’t press the accelerator when parking, just let it reverse into the parking space on its own, unless the space is tight and I need to go faster, then I lightly tap the accelerator. Safety is the most important thing—I always check the rearview mirror and the reversing camera before reversing to ensure there are no people or obstacles. Don’t go too fast; moving too quickly can easily lead to scraping the wall or damaging the car. Take your time when reversing—it’s safer and more efficient. Remember that when reversing on a slope, you may need to press the accelerator slightly to prevent rolling. Developing good habits, such as checking the surroundings before reversing, can avoid a lot of trouble.
