The reason for the right side narrowing during right reverse parking is steering the wheel too early. Here are the precautions for reverse parking: To perfectly enter the parking space during reverse parking: The timing of turning the steering wheel clockwise is crucial—it should be neither too early nor too late. If steered too early, it's easy to hit the right parking line; if too late, it's easy to hit the left parking line. This requires accurate judgment. Keep the speed slow: During reverse parking, the most important thing is to maintain a slow speed. If there's any deviation while reversing, the car's body may tend to touch the line. Timely detection allows for corrections, such as promptly straightening the steering wheel. However, if driving too fast, there won't be enough time to make adjustments.

When the car body gets closer and closer to the right-side parking line during reverse parking, it's mostly because you turned the steering wheel back too early. During the reverse parking process, turning the steering wheel too early causes the car body to turn inward prematurely, resulting in a very narrow space on the right side and a large gap left on the left side. For example, if you turn the steering wheel back before the reference point is reached, the front of the car hasn't fully entered the parking space, and the right front corner hits the parking line too early. At this point, don't force the reverse; instead, drive forward half a meter to readjust, and try turning the steering wheel again after the parking line disappears from the rearview mirror. Next time, remember to turn the steering wheel back a bit later. After the car body is parallel to the parking line, straighten the steering wheel in one go to avoid crossing the line.

I used to make this mistake all the time when practicing parking. A narrow right reverse parking is 90% caused by turning the steering wheel back too early. Because you retract the wheel too quickly, the rear of the car hasn't fully swung into the space before you straighten the wheel, causing the right rear wheel to get too close to the parking line. Here's how you can judge: if you notice the door handle in the right mirror is about to scrape the edge of the parking space before the steering wheel is fully straightened, then you've definitely turned back too early. At this point, immediately brake, shift into drive, and steer slightly to the left to move the front of the car outward and create space before reversing again—this is much safer. The key is to closely monitor the relationship between the right corner of the parking space and the rear wheel.

The key to this issue lies in the timing of steering wheel operation. When the right side is narrow and the left side is wide during right reverse parking, it usually indicates that the steering wheel was turned back too early. The reason is that turning the wheel prematurely causes the rear wheel trajectory to shift inward too quickly, resulting in being too close to the right parking line. Here's a trick to correct it: stop immediately when you notice the right side becoming narrow, turn the steering wheel fully to the right while stationary, and reverse. When the rear wheel approaches the side line, quickly turn the steering wheel to the left to use the outward swing of the rear wheel trajectory to adjust the space. Pay special attention to the angle change between the car door and the parking line in the right rearview mirror; a distance of two fingers' width is considered safe. Practice this several times during training to get the hang of it.

Steering wheel returning too early will press against the left corner of the garage, but the space on the right side shrinks rapidly, which definitely indicates premature wheel return. The principle is simple: turning the wheel too early reduces the turning radius of the car's front, causing the right front wheel to start turning inward before passing the right angle. Just like a novice I saw yesterday, who hastily returned the wheel as soon as the rearview mirror passed the pillar, resulting in the garage corner line disappearing too quickly in the right rearview mirror. The correct approach is to wait until the car body is parallel to the garage boundary line before returning the wheel. At this point, the right rearview mirror will show the garage boundary line extending steadily like a parallel straight line, with roughly equal space on both sides. If it feels too narrow, don't force the reverse; starting over is safer.

The driving instructor said turning the wheel too early makes the space narrow, while turning too late makes it wide. Hitting the line on the right during right reverse parking is mostly due to hasty steering: 1. Turning the wheel fully right too early causes premature entry angle; 2. Not waiting for the car body to align before straightening the wheel; 3. Attempting to reverse when the car isn't properly positioned. Checking the rearview mirror is most intuitive: if the distance between the wheel and the parking line in the right mirror is less than three fingers, it's definitely too narrow. Once I almost hit the line because I kept reversing when the rear door handle was only a fist's width from the white line. An emergency solution is to turn left while reversing to create space by swinging the rear right, but for beginners, it's safer to just restart.
