How many points are deducted for crossing the line on an S-curve?

[StMalachi]

In the Subject 2 driving test, "crossing the line on an S-curve" will result in a failing grade. The regulation states that if the wheels run over the edge line of the road during curve driving, 100 points will be deducted. Subject 2 test deduction code 10114 specifies: Driving over the solid center line or edge line of the lane, deduct 100 points. Precautions for curve driving are: Item 1: Maintain first gear throughout the drive, and avoid turning the steering wheel too sharply. Item 2: After entering the curve, try to take a wide turn. When driving into a right curve, keep the right wheel close to the right edge line, and vice versa. Item 3: While on the curve, use the steering wheel to ensure the small rearview mirror on the inner side of the car's hood always stays at the edge of the outer white line—neither crossing the line nor staying too far from the edge line. Item 4: Adjust the direction promptly based on the curve's characteristics and the rear wheel's radius.

I just finished practicing the curve driving in Subject 2, and I’m very clear about the consequences of crossing the line in an S-curve. During the test, even if the wheel lightly touches the sideline, you’ll fail on the spot—it’s the same as being directly deducted 100 points. During practice, the instructor always kept an eye on our steering wheel angles, saying that if you cross a solid line while actually driving and get caught by a camera, it’s a violation of prohibited markings, resulting in a 1-point deduction and a 200-yuan fine each time. The most common moment for crossing the line in a curve is when you turn the wheel back too late while exiting the curve. Now, I slow down in advance when taking curves and keep an eye on the wheel position through the rearview mirror. Actually, with a few more practices, beginners can develop a sense of the car’s position. If you’re still struggling, ask the instructor to watch your trajectory from outside the car.

Having driven for fifteen years on all kinds of mountain roads, I can say that crossing the line on S-curves is something you really can't take lightly. During the driving test, crossing the line means an instant fail with zero points. On actual roads, if you cross a solid line and get caught on camera, it's a surefire 1-point deduction plus a 200-yuan fine. The worst was when I saw my friend, a new driver, get caught by a surveillance camera for barely grazing the line with the front wheels while turning. This kind of line-crossing on curves is most dangerous in rainy weather when tire grip is poor, making skidding and loss of control more likely. When teaching my students how to navigate curves, I always tell them to keep their speed under 30, avoid turning the wheel too sharply, and follow the curve of the lane line gradually. It's safest to maintain a two-finger width between the wheels and the edge line in the rearview mirror.

Over the years of teaching, I've explained curve negotiation techniques to thousands of students. During driving tests, crossing the line in an S-curve results in immediate test termination with a full 100-point deduction. In real-world driving, crossing solid lines violates traffic markings regulations, typically incurring a 1-point penalty and 200-yuan fine in 99% of cases according to traffic laws. Pay special attention to consecutive S-curves on highway ramps - the yellow solid lines on the ground are particularly easy to overlook. For proper cornering, focus your gaze on the apex in the distance and steer with alternating hand movements like turning clock hands. You have adjustment opportunities until the tires are within 5cm of the line. Remember, the outer edge of the curve is most prone to line violations - slightly easing off the throttle can prevent this.
