How is the vehicle body crossing the line determined in Subject 2 test?

Before the vehicle enters the right-angle turn, it should drive close to the right side, maintaining a distance of about 0.1 meters between the right wheels and the right edge of the road. When entering the "S" curve, the vehicle should enter the curve from the right side of the road and maintain a uniform low speed. During parallel parking, maintaining an upright sitting posture is crucial for accurately judging various reference points. Turn on the right turn signal, steer the wheel appropriately to the right, and drive slowly along the right side of the road, paying attention to the distance between the vehicle body and the right edge line.
The criterion for determining if the vehicle body crosses the line in Subject 2 of the driving test is very clear. As long as any wheel of the test vehicle touches the ground markings or the projection of the wheel in the air crosses the line, it is considered a violation. Specifically, in different test items: for example, during reverse parking, if the rear of the car sweeps the line while reversing, or after entering the parking space, the left or right side of the car body presses against the yellow boundary line of the parking space; during parallel parking, if the front wheels run over the extended line of the parking corner when exiting; during curve driving, if the rearview mirror shows the tires are close to the yellow line but the steering wheel hasn't been turned yet; after a right-angle turn, if the rear wheel presses against the right-angle line; or on the slope, if the front bumper exceeds the stopping line range. These violations are directly scored by the invigilation system through sensors. The key to avoiding body line crossing is wheel positioning. It's best to develop the habit of checking the distance between the tires and the boundary line via the rearview mirror during practice, rather than just focusing on the front hood of the car. Even if the front of the car doesn't cross the line but the wheels do, points will still be deducted—this detail can be quite tricky.
I took the Subject 2 test last year and failed once due to crossing the line. At the time, after completing the reverse parking, I thought the car was parked quite straight, but the system immediately reported that the car body had crossed the line. Later, my coach showed me the replay of the surveillance footage, and I realized that the left rear wheel was right against the corner line of the parking space but not inside it. During the test, the sensors on the ground are extremely sensitive; as long as the wheel touches the line, it triggers an alarm. Each test item has boundary requirements: for hill parking, the front bumper must be within a 30 cm range in the middle of the stop line; for right-angle turns, the rear wheels must completely pass the corner point to be considered safe; if the wheels touch the outer yellow line during curve driving, you fail immediately. During practice, it's best to have the coach record the position with a phone, especially focusing on the distance between the tires and the boundary in the rearview mirror—being just two fingers' width away is dangerous.
Over the years of coaching, the most frequent reminder for students is the issue of the vehicle crossing the line. The core criteria for judgment are three points: wheels must not press on solid lines, the body projection must not exceed boundaries, and parking positions must be precise. For example, after reversing into the parking space and stopping, any part of the vehicle exceeding the parking line; during parallel parking, the rear of the car sweeping the simulated curb line; pressing the corner during a right-angle turn; or the bumper exceeding the stop line area during a hill start—all these count as crossing the line. It is recommended that students practice by stopping the car and stepping out to check the position themselves to develop spatial awareness. The height of the test car's seat can affect the reference points, so it should be adjusted in advance. Also, avoid turning the steering wheel too sharply, as it can easily cause the tail to swing and sweep the line. Using the raised points on the wiper to align with the line is the safest method, far more accurate than relying on guesswork.
