Here are the specific techniques for finding 30 cm during hill start: 1. Observe the position of the engine hood: After hearing the voice prompt, you need to drive forward and to the right. When you see the right front corner of the engine hood at 1/3 of its length align with the roadside line, the distance between the car body and the roadside line is exactly 30 cm. 2. Look at the raised part of the wiper: From the driver's seat, when the raised part of the wiper aligns with the right roadside line, the distance is approximately 30 cm. 3. Look at the right front door handle: Observe the right front door handle in the right rearview mirror. If the right front door handle is tangent to the right roadside line, the distance is just right; if it's too far, you need to slightly adjust the direction; if it's too close, there is a risk of crossing the line.
I remember when I first learned hill starts, that 30 cm distance always gave me a headache. Later, I found a simple visual reference point: sitting in the driver's seat, leaning slightly to the right, aligning the right door handle with the roadside curb or markings. If the entire handle isn't visible, just showing the front two-thirds is about right. The car should roll slowly, don't accelerate too quickly, and gently steer a bit to the right to maintain parallel movement. During the test, getting this position wrong would cost points, so I practiced for half an hour every day, repeatedly simulating in an empty parking lot until I got the hang of it. Now I'm quite accurate—the key is not to panic. After stopping the car, step out to check the distance, and once muscle memory kicks in, it becomes easy. On hills, you also need to control the clutch steadily to prevent wheel spin and wasted effort. In short, practice is most important, and safety comes first!
When teaching someone to drive, I found that mastering the 30 cm roadside positioning on a slope hinges on three key points: First, body posture—sit straight without tilting your head, glance at the right rearview mirror, and align the mirror's bottom corner with the road edge line. Second, steering control—turn gently, avoiding abrupt movements, and keep the car parallel without deviation as it rolls slowly. Third, use reference points on the car body, such as aligning the raised part of the right wiper with the curb—once it matches, you're in position. With practice, you'll develop a feel for it. Many overlook the practice environment; choose a sloped open area or simulate an exam route, roll down a few meters to check the distance, and adjust if needed. Avoid slamming the brakes on a slope, as locked wheels make control harder. Be patient—a week of practice leads to proficiency, reducing exam stress.
Having driven for decades, I rely on an old saying to find the 30cm mark during hill starts: 'Keep the right wheel close to the edge and creep slowly.' Don't press the accelerator when starting—just use the clutch to control the sliding speed. Glance at the right side mirror, aligning its lower edge with the roadside line; locking it in place is the ideal position. If the curb isn't clear, use roadside grass or stones as reference. Keep movements steady, avoid tilting the car body, and slightly turn the steering wheel to the right. Practice makes it instinctive, saving effort and hassle.
