How to determine 30 centimeters for the right reverse parking in Subject 2?
3 Answers
To judge the 30-centimeter distance for the right reverse parking in Subject 2, you need to learn to observe the distance between the tire and the corner of the parking space in the rearview mirror, with a two-finger width being the accurate distance. Below are the related instructions for the right reverse parking: 1. Solution for steering too early: The car is too close to the upper right corner of the parking space, less than 30 centimeters or unable to enter the space at all; Solution: Turn the steering wheel back half a turn or a full turn (the exact amount depends on the situation, possibly 3/4 of a turn), wait until the right rear wheel enters the space beyond the upper right corner (do not turn the wheel back immediately when the right rear wheel just enters), then continue to turn the steering wheel fully to the right. When the car body is almost but not completely straight, straighten the steering wheel. 2. Solution for steering too late: The car is too far from the upper right corner of the parking space, more than 30 centimeters, and the left rear wheel is prone to pressing the left line; Solution: Upon noticing in the rearview mirror that the tire is too far from the upper right corner of the parking space, immediately check the left rearview mirror. Do not turn the steering wheel back at this time; let the car tilt until the left rear wheel enters the space beyond the upper left corner, then straighten the steering wheel and continue to turn the steering wheel to the left. When you see in the rearview mirror that the right side is safely inside, immediately check the left rearview mirror. When the car body is almost but not completely straight, straighten the steering wheel and park the car.
I remember when I was learning to drive and taking the Subject 2 test, the most frustrating part was judging the 30-centimeter distance for the right reverse parking. The instructor always emphasized checking the right rearview mirror, but in practice, I found relying solely on sight wasn't accurate. My approach was to first align the car body parallel to the parking line, then reverse slowly while focusing on the gap between the car body and the line in the right rearview mirror. When the car body appeared parallel to the line in the mirror, if the line was about a palm's width visible at the rear half of the car, that roughly indicated 30 centimeters. If it felt off, I made minor steering adjustments without rushing. I recommend practicing to develop a feel for the car—find an empty space to repeat the maneuver, paying attention to the car's dimensions and rearview mirror distortion. Over time, you'll naturally grasp the pattern, and during the driving test, you won't panic. Practice trumps reading instructions a hundred times, especially for beginners who need patience to accumulate experience.
In my teaching process, I've noticed many people struggle with determining the 30 cm distance for the right reverse parking in Subject 2. The basic steps are: first, park the car correctly aligned with the reference point, then slowly reverse while observing the right rearview mirror. When the car body is parallel to the parking line, the distance in the mirror should be maintained at about 1.5 times the width of the rearview mirror, which is roughly 30 cm. I teach students to use the edge of the rearview mirror or specific points on the car body as reference aids, such as a small segment outside the mirror frame. The key point is to make slight steering adjustments during reversing to maintain parallelism, avoiding turning the wheel too early, which could result in the distance being too far or too close, leading to crossing the line. A common mistake is misjudging the angle due to nervousness, so I encourage students to practice more with simulations, setting up ground markers or cones to improve their sense of distance. Practice makes perfect, and staying calm during the test will ensure success.
