The standard for Subject 2 driving test is that tires must not cross the line. Mastering vehicle speed: When driving through curves, it's crucial to time your maneuvers correctly and maintain proper speed. Use the clutch and brake to control speed. Before entering a curve, try to stay close to the right side of the lane to avoid crossing the line. Understanding vehicle steering: A vehicle's minimum turning radius refers to the radius distance traveled by the outer front wheel during a turn. When the steering wheel is turned to its maximum position, the vehicle typically turns at its lowest stable speed. The minimum turning radius largely determines a vehicle's ability to navigate narrow sections and overcome obstacles. Generally, the smaller the turning radius, the better the vehicle's dynamic performance. Measurements show that compact cars have a minimum turning radius of 6 meters, while mid-size vehicles range from 8 to 12 meters. A vehicle's minimum turning radius directly affects driving safety.

When I was preparing for the driving test's Subject 2, I focused heavily on the curve driving exercise. The instructor repeatedly emphasized that not letting the tires touch the lines was one of the key criteria for passing. During the test, as long as you drive steadily through without the wheels touching those white boundary lines, the examiner will generally mark it as a pass. However, don't be naive thinking that just focusing on the tires is enough—the test also evaluates overall performance, such as keeping the car body from getting too close to the line zone, controlling speed to avoid skidding, and turning the steering wheel smoothly without hesitation. I failed because I drove too hastily—the car body grazed the edge even though the tires didn't touch the line. So, during practice, it's essential to simulate real test scenarios and develop good habits. Remember a small trick: use the rearview mirror to observe the rear wheel's position and adjust the steering angle in advance, which helps you avoid the lines steadily and score full marks effortlessly.

I've practiced curve driving many times. At first, I thought it was safe as long as the tires didn't cross the line, but the instructor corrected me, saying that's just the basic requirement. During the test, the vehicle must drive through the entire curve area without sudden stops or excessive deceleration, otherwise points may be deducted even if the line isn't crossed. The car body must not touch protective poles or other obstacles, and tilting can also affect judgment. From a beginner's perspective, I suggest starting at low speed during practice, keeping an eye on all directions instead of just looking down at the wheels. Exam pressure can easily lead to mistakes, so staying relaxed is crucial. In actual driving, excessive speed may cause tailspin, making it dangerous whether you cross the line or not, so safety first is the core principle. I recommend participating in more mock exams to develop stable handling skills and not relying on luck.

The core of curve driving is not to cross the line. The exam rules clearly state that passing is achieved as long as the wheels do not touch the edge line. However, we have observed many trainees often overlook potential issues caused by unbalanced vehicle posture or excessive speed. The exam requires full monitoring; generally, there's no problem if the tires don't cross the line, but don't let your guard down. For example, entering and exiting curves should be smooth, steering wheel operation must be accurate to avoid jerking. As a driving instructor, we recommend using reference points during practice, such as aligning the edge of the vehicle's hood with the midline of the curve. Safety is paramount; maintaining a speed of around 15 km/h is optimal, as higher speeds increase risks. Overall, the focus of Subject 2 is on habit formation—not crossing the line is the baseline, but the details of technique determine success or failure.
