What is the reason for always hitting the corner when reversing into the garage?

Right garage starting point, the car body is too far from the left side of the garage area boundary line, missing the optimal parking position for the starting point of reversing into the garage. The following is a related introduction about reversing into the garage: 1. Overview: Reversing into the garage is a mandatory test item for obtaining a small car driver's license after 2013. It assesses the driver's ability to operate the car in a specific area. Reversing into the garage is one of the assessment points in the driver's test, which involves correctly reversing the vehicle into the garage from both sides while in motion. There is a time limit for reversing into the garage during the test. 2. Methods: There are three most common types of reversing: The first is the "non"-shaped reversing into the garage, commonly seen in various large shopping malls. The second is the roadside "one"-shaped reversing into the garage, commonly known as parallel parking. The third is the less common diagonal reversing into the garage. 70% of driving students believe that parallel parking is slightly more difficult.

When I was learning to drive, my instructor said there are usually several operational mistakes when reversing into a parking spot and hitting the corner. First, the initial parking position isn't aligned properly—if the car is too close or too far from the edge line of the parking space, it can easily throw off the angle. Second, the timing of turning the steering wheel is incorrect—turning too early may cause the rear of the car to sweep the outer corner, while turning too late may scrape the inner corner. Third, reversing too quickly makes it hard to correct the direction in time. It's recommended to start reversing when the car is about 1.5 meters away from the edge line, then turn the steering wheel half a turn when the rear wheel approaches the corner in the rearview mirror for adjustment, while steadily pressing the clutch to control the speed. Practice more to get a feel for how the rear of the car swings, and it will become easier over time.

As someone who's been through it, the most frustrating part about cornering in the garage is the inflexibility in steering adjustments. Many beginners just memorize the reference points taught by instructors, but when faced with actual variations in garage dimensions, they can't adapt. In reality, you should turn the steering wheel gently like rotating a plate—slow to turn and slow to return. If you notice the car body is less than half a foot from the corner in the left mirror, start returning the wheel, then fully steer again once the rear swings into the garage. Also, setting the seat too low affects visibility, causing the corner to disappear too quickly in the mirror and leading to misjudgment. I only realized after recording my practice sessions that every time I hit the corner, it was because I turned the wheel after my shoulder passed the corner—when I should've started half a car length earlier.

Having worked on cars for over a decade, I've encountered numerous issues with driving school vehicles hitting corner markers during parking exercises, with mechanical factors accounting for about 30% of cases. Uneven tire pressure can cause deviations in left-right turning radius—for example, if the left front tire is underinflated by 1.0 bar, the right rear wheel is more likely to hit the corner during reversing. Excessive steering linkage play is the most hidden issue, where the wheels only respond after 15 degrees of steering wheel movement—this dead zone gets magnified during reversing. Additionally, worn rear suspension bushings in older vehicles can alter rear wheel trajectory due to body roll. I recommend checking that left-right tire pressure differences don’t exceed 0.2 bar before practice sessions and testing steering free play by shaking the wheel while stationary. If mechanical issues are detected, avoid forcing practice—get them adjusted at a repair shop first.

The key to avoiding corner clipping while reversing lies in spatial awareness. Here are three practical tips: First, use reference points instead of memorizing fixed positions—for instance, turn the wheel when the parking corner appears at the lower edge of the driver's window. Second, intentionally pause twice during reversing to make corrections—once when the corner is about to disappear and again when it completely vanishes. Third, mark safe distance indicators on your side mirrors with tape. Additionally, don’t overlook the impact of ground slopes. Once, in a rainy day at a sloped garage, my car’s rear automatically shifted due to gravity, causing a corner clip. Now, I lightly tap the accelerator before engaging reverse gear to test the slope and adjust accordingly.

Last time when accompanying my wife for driving practice, I noticed she kept hitting the right corner of the garage. After observing for a while, I realized it was a sightline issue. She habitually stretched her neck to look at the rear window, consequently neglecting the warning distance in the right rearview mirror. The correct approach is to keep her back against the seat and use peripheral vision to simultaneously scan both left and right rearview mirrors. When the garage corner in the right rearview mirror is about 30 centimeters away from the edge of the car body, that's the critical point for adjustment—either quickly turn the steering wheel back to correct the direction or move forward slightly for fine-tuning. There's also an ergonomic reason: at 156 cm tall driving an SUV, the garage corner appears smaller in the rearview mirror, leading to misjudgment of distance. Adding a wide-angle convex mirror solves the problem.
