You need to press the brake when reversing. In fact, it's best to keep the brake pressed continuously. If you can ensure that the test vehicle doesn't roll in the garage, not pressing the brake is also acceptable. When shifting gears, the vehicle is required to be in a stopped state. If the vehicle rolls, it may be judged as a failure. Below are the specific introductions to the gears of an automatic transmission car: R Gear (Reverse Gear): When this gear is engaged, the hydraulic system's reverse gear oil circuit is connected, causing the drive wheels to rotate in reverse, enabling the vehicle to move backward. N Gear (Neutral Gear): When the neutral gear is engaged, the planetary gear system idles and cannot output power. D Gear (Drive Gear): When the gear shift lever is in this position, the hydraulic system control device automatically connects the corresponding forward gear oil circuit based on the throttle opening signal and the vehicle speed signal. It can automatically shift up or down according to the driving speed, achieving the automatic transmission function.

I used to struggle with this when I first started driving. You must press the brake when reversing, mainly to control speed and ensure safety. In an automatic transmission car, if you don't press the brake while shifting into reverse, the car will slowly roll, which can be especially panic-inducing for beginners. Manual transmission cars can use the clutch to control, but on steep slopes, not using the brake can be very dangerous. Once, I was reversing in a narrow alley, only pressing the clutch, and the car suddenly rolled backward on the slope, almost hitting a wall. Now I've developed a habit: always keep my foot on the brake pedal ready to stop at any moment. The blind spots in the rearview mirror are large, and sometimes children or pets suddenly appear, leaving no time to react. Safety comes first—hold the brake and reverse slowly; it's always the right approach. After all, repair costs are much higher than fuel expenses.

Applying the brake while reversing is a fundamental driving principle. Reverse gear delivers more aggressive power output compared to forward gears, especially in automatic transmission vehicles. I've encountered numerous cases where drivers relied solely on idle speed for reversing without brake application, resulting in scraped walls or collisions with posts. Parking lots truly test one's skills—extra caution is required in narrow spaces or on slopes. Once while reversing in an underground garage, a slightly heavier press on the accelerator caused me to tap a pillar before the rearview camera could even respond. A mechanic later advised me that the safest approach is to always hover the right foot over the brake pedal during reverse maneuvers, ensuring instant stopping capability. Now I strictly limit my reversing speed to under 5 km/h with my right foot perpetually brake-ready.

The answer depends on the situation. On flat ground, experienced drivers might not need to constantly brake while reversing. But on slopes, you must use the brakes! I learned this the hard way driving a manual—thinking clutch control alone would suffice on an incline, only to roll back and bump someone's bumper. With automatics, extra caution is needed as reverse gear delivers strong torque; even light throttle input can cause sudden movement. Cars with auto-hold function are simpler—they automatically brake when stopped, requiring just a gentle throttle tap to proceed. Given reversing's many blind spots, I recommend keeping your foot hovering over the brake pedal. Especially in rain when tire grip weakens, slight acceleration can easily induce skidding. Safety isn't about gambling with odds.

Let me analyze the principle for you: When reversing, the engine outputs high torque, and the automatic transmission has high efficiency, causing the car to move faster without brake application. Many collisions occur during reversing. My neighbor scraped a fire hydrant last month while reversing precisely because they didn't use the brakes to control speed. Pay special attention to two points: first, wet roads after rain have reduced friction, and second, severely worn tires increase the risk of losing control. Now I always use the 360-degree camera along with the brake when reversing. Some people think frequent braking wastes fuel, but in reality, short-distance reversing consumes negligible amounts. Reversing sensors only measure distance – speed control still relies on the driver. Keeping your foot on the brake is the safest approach.

As a parent who frequently picks up and drops off kids, I'm extra cautious when reversing. I always keep my foot on the brake to control speed because the blind spot behind the car is larger than imagined. Once while reversing in my neighborhood, a child suddenly ran behind my car - if my foot hadn't been on the brake, I wouldn't have stopped in time. The idle speed in reverse (R) gear for automatics is actually quite fast, so beginners should lightly press the brake. While manuals can use clutch control, mistakenly pressing the wrong pedal in panic is even more dangerous. Special reminder for cars with auto start-stop: the engine may suddenly restart while reversing, potentially causing lurching forward without brake pressure. My habit is to disable start-stop first when getting in the car - keeping steady brake pressure while reversing is the golden rule.
