The distance between the car body and the road edge line should appear as "1 to 3 fingers' width" in the rearview mirror. Below are some scoring criteria for slope parking in Subject 2: 1. Scoring standards: If the vehicle's front bumper or motorcycle's front axle is not aligned with the pole line after stopping, and the deviation exceeds 50 cm, it results in failure; if the deviation does not exceed 50 cm, 10 points are deducted (originally 20 points). 2. Precautions: Accurately estimate the target, using a specific point on the parking pole and the windshield (or engine hood) as a reference (this point should be determined during practice due to differences in vehicle models and driver heights). When the reference point on the windshield aligns with the parking pole in a straight line, indicating the vehicle's bumper is aligned with the pole line, stop immediately.

I've taught many students how to perform hill-start parking, and the key to stopping within 30 cm on an incline lies in observing the side mirrors. When you park on a slope, the gap between the tire and the curb in the right side mirror should appear extremely small, almost as if they're touching. At this point, the lower edge of the tire will obscure part of the curb, making it look like a line is about to break—that's your 30 cm reference point. Beginners might find it tricky at first, but with the side mirror properly angled toward the ground and some practice, they'll develop an intuition. I also recommend using the vehicle's body alignment as an additional reference to coordinate the overall judgment, avoiding reliance solely on the mirrors to prevent errors. Safe driving relies on accumulating these small techniques to ensure both test success and accident prevention.

During driving lessons, the hill start was my biggest headache. The instructor always taught me to use the rearview mirror to judge the 30 cm distance. Sitting in the driver's seat, I'd nervously glance at the right rearview mirror: when the tire and curb got so close that the gap was almost invisible, the position was about right. At first, I kept making mistakes, but later I realized that when viewed from the edge of the mirror, the curb line was just slightly blocked by the tire—that was the accurate position. Now, when parking on a slope, I naturally use this trick, which is really helpful. Real road conditions vary, but by relying on the mirror as a reference, I've developed a habit that helps avoid hitting the curb or parking too far and obstructing traffic. Learning to drive isn't easy, but memorizing such visual cues brings many benefits.

Judging a 30cm distance by checking the rearview mirror when parking on a slope is a fundamental driving skill crucial for safety. When I drive, I observe the relationship between the tire and the curb in the right rearview mirror. When the gap narrows to almost disappearing, the distance is accurate. This helps prevent scraping the curb or parking too far and blocking the road. It's a simple and easy-to-learn method that becomes intuitive with practice, forming a habit that reduces risks.

The reference for the rearview mirror when parking on a slope relies on the principle of visual perspective. When parking uphill, adjust the right rearview mirror angle to clearly display the tire and curb position: at 30 centimeters, the outer edge of the tire will partially obscure the curb line, making it appear as if it's touching. From my experience, once the mirror is properly adjusted, you can see clearly without complex calculations—just practice a few times. This method saves time and improves parking efficiency.

Here's a handy trick for daily uphill parking - using the side mirrors is the easiest method. When the tire and curb appear almost touching in the mirror with barely any gap visible, that's approximately 30 centimeters. My driving instructor taught me this technique during lessons, and now I've mastered it perfectly - I even use it to guide my novice driver friends. This practical method ensures fast, accurate parking while preventing scratches and collisions. Remember to practice regularly to reinforce this skill.
