How to judge the 30cm distance on the right side during hill start?
4 Answers
There are mainly three methods to handle the 30cm distance on the right side during hill start. Below are detailed introductions of these three methods: 1. Using the wiper: For vehicles equipped with wipers, adjust your sitting position and observe the root of the wiper. When the point at the wiper's root aligns with the extension line of the right boundary line, the right wheel will be 30cm away from the boundary line. 2. Using reference points: Use the central disk on the hood as a reference point. Draw a vertical tangent line from its right side with a five-finger width, and align the leftmost edge of this five-finger width with the inner side of the white line. By driving in this manner, the right wheel will be within 30cm of the boundary line. 3. Using the rearview mirror: Observe the small mirror on the front of the vehicle; when the boundary line touches the vehicle body, the distance is appropriate.
When I first learned to drive, I really struggled with judging the 30cm distance on the right side during hill starts. A friend taught me a simple trick: focus on the midpoint of the right wiper blade and align it with the roadside line or the edge of an obstacle on the slope. This usually gives you about 30cm on the right. You need to keep the car steady to prevent rolling back, and adjust the side mirror properly to see the side profile. Practice several times in a safe area, using chalk or cones as markers for better observation. Remember, visual errors can be significant, so avoid tilting your head or squinting—maintain an upright posture to prevent misjudgment. Combine this with hill-start techniques like gently pressing the accelerator while coordinating with the handbrake. With practice, you'll naturally get it right. Don't rush to perfect it all at once.
The key is to use the right reference points to make it easy. First, adjust the rearview mirror to ensure a clear view of the right side. When starting on a slope, glance at the mirror to check the right wheel or body line, leaving a small palm-width gap, roughly corresponding to 30 cm. Don’t rely solely on feeling, as errors can be large. Aligning the wiper position with the roadside line is more accurate. Practice frequently in daily driving to familiarize yourself with the reference points. During the test, stay calm—as long as you don’t cross the line, you’ll pass. Safety first: avoid getting too close to the roadside to prevent scratches. If your view is blocked, adjust the steering gently. Repeated practice is the key—practice makes perfect.
When starting on a slope, the easiest way to confirm the 30cm distance on the right side is by using the rearview mirror. Adjust the car's front so that the side mirror can see the edge of the tire or maintain a distance between the car body and the roadside of about a palm's width, approximately 30cm. Don't be careless about this during the driving test, as it's easy to lose points. In actual driving, practice more, like aligning with the wiper node for steadiness, ensuring both safety and efficiency.
