What Causes the Vehicle Body to Cross the Line After Parallel Parking?

[LaLuke]

Parallel parking with the vehicle body crossing the line means that the body's projection has already exceeded the line, which is considered as touching the line in the driving test. Additional information: The driver's license examination is a test to obtain a motor vehicle driver's license. The content and passing standards of the examination subjects are uniformly set nationwide. The examination is divided into three subjects and four tests, covering theoretical knowledge, field driving skills, road driving skills, and civilized driving-related knowledge. The examination subjects are as follows: 1. Subject One: Examination on road traffic safety laws, regulations, and related knowledge. The structure and basic question types of the examination question bank are formulated by the Ministry of Public Security, and provincial-level traffic management departments of public security authorities establish the examination question bank for their respective provinces (autonomous regions, municipalities) based on local conditions. 2. Subject Two: Examination on field driving skills. The test items include: reversing into a parking space, stopping and starting on a slope, turning at a right angle, driving along a curve, and parallel parking. In cities like Shanghai, Subject Two consists of nine mandatory test items: reversing into a parking space, turning at a right angle, parallel parking, driving through a tunnel, stopping to take a card, driving along a curve, making a U-turn on a narrow road, emergency stopping, and stopping and starting on a slope. 3. Subject Three: Examination on road driving skills. The basic test items include: preparation before starting (walking around the vehicle counterclockwise, fastening the seat belt, turning on the left turn signal, shifting gears, releasing the handbrake, and honking the horn), starting, driving straight, changing lanes, passing through intersections, parking by the roadside, passing through pedestrian crossings, passing through school zones, passing through bus stops, meeting vehicles, overtaking, making U-turns, and driving at night. 4. Subject Four: Examination on safe and civilized driving knowledge. Test items: knowledge related to safe and civilized driving.

When the car body crosses the line during parallel parking, it's usually due to my driving technique issues. I often find myself turning the steering wheel too late or not straightening it in time, causing the tire trajectory to deviate too much and directly cross the line. Another reason is improper speed control, such as reversing too quickly, leaving no time for minor adjustments, resulting in the car body tilting and going out of bounds. I've also experienced inaccurate perception of the car's dimensions, especially when driving larger vehicles like SUVs, where blind spots are more common, and visual distance judgment can be off, making it easy to cross the line. It's recommended to practice more with empty parking space simulations or attach small mirrors inside the car to assist with observation, which can help reduce mistakes. Additionally, always check the position before parking to ensure there's enough space, avoiding sudden braking that could cause the car to jerk forward due to inertia. In daily driving, I always leave some margin, take it slow, and don't rush—skills will naturally improve over time.

The reasons for the vehicle crossing the line, which I have encountered several times while driving, are mainly related to the vehicle itself. For example, uneven tire pressure causes the softer side to bear different forces, making the direction easily deviate when parking, resulting in crossing the line. Additionally, an aging steering system, like in my old car, where the steering wheel had too much play, made fine adjustments difficult, causing the car to suddenly cross the line. Moreover, improperly adjusted rearview mirrors can easily lead to misjudging angles, especially at night when the lighting is dim, making it hard to see the boundary lines. It is recommended to regularly check tire pressure and steering components during maintenance to ensure the vehicle is in good condition; before parking, take a quick look around to confirm the environment and whether the lines are clear. If the space is too narrow, simply find another spot to park. I think installing a reversing camera as an assistive device is quite effective, as it allows real-time monitoring to avoid crossing boundaries, ensuring safety and peace of mind.

Sometimes after parking, I notice the car body is out of line, which is mostly caused by operational errors. For example, turning the steering wheel too sharply without properly controlling the turning radius can cause the tires to slide out and cross the line. Or driving too fast when reversing, where the inertia is strong, making it hard to maintain the car's balance. It could also be due to lack of experience; I often did this as a beginner when I hadn't practiced enough. Finding an empty parking space to practice repeatedly, gradually getting used to the angles and sense of distance, will reduce such problems.
