Which point on the wiper should be used to judge 30 centimeters in Subject 2?

In Subject 2, the 30-centimeter distance can be judged by observing the position between the right wiper's root and the right spray nozzle. Below is an introduction to the relevant content of the Subject 2 test: 1. Test requirements: The requirement for parallel parking is that the driver must park the vehicle in the right parking space without the wheels touching the lane boundary or the parking space boundary. 2. Content and requirements of Subject 2: The five assessment items are reversing into a parking space, parallel parking, stopping and starting on a slope, turning at a right angle, and driving on a curved path. Subject 2 requires 26 class hours, with 2 hours dedicated to theoretical knowledge, so in practice, it is 24 class hours.

I remember in driving school instruction, the 30 cm reference point for Subject 2 test is usually judged by the raised part or corner of the windshield wiper. When reversing into a parking space or pulling over, you need to align that protruding part of the wiper with the edge of the roadside line, so the wheels will be approximately 30 cm from the curb. As an instructor, I often remind students to first adjust the seat to the proper position to ensure stable visibility, then practice repeatedly with auxiliary lines drawn on the training ground—don't rely on rote memorization. If the wiper type differs (e.g., some cars have ball-shaped wiper heads), you must actually measure the wheel distance to calibrate. This reference point is crucial during the test because being too far or too close will affect the reversing angle or cause failure by crossing the line. I recommend combining it with rearview mirror observation for an overall view and practicing more to get the feel—safety first to pass the test.

That's exactly how I practiced for my driving test's second subject. Just align the 30 cm mark on the wiper with a prominent point—like the raised corner of the wiper head—and keep it parallel to the roadside line while parking, and you'll nail it. On the test day, my instructor told me to straighten the car slowly, lower my line of sight a bit, and make sure the raised point aligns perfectly with the curb. I had tried it several times in my neighborhood before. If the wiper gets blurry or it's raining, clean it first before using it, as poor visibility can easily lead to mistakes. Don’t rely solely on this point, though—also check the wheel position and rearview mirror. During practice, measure 30 cm and mark it to get the hang of it. Learning to drive takes patience—just go a few more rounds, and you'll find the trick. Passing on the first try isn’t that hard.

Simply put, for the 30 cm reference point in Subject 2, align the protruding part of the windshield wiper with the roadside line. Ensure the vehicle is completely stopped during operation, and the alignment point is clear. Avoid turning your head too much during reversing as it may affect judgment. I rely on this technique during practice. After getting in the car, find the correct reference position and try it several times—it feels intuitive and reliable.

From experience, the raised point on the wiper is a great helper for the 30 cm rule. Aligning it with the roadside line during reverse parking can save a lot of trouble. I must remind you to control the distance more accurately during the test to avoid mistakes like crossing the line or grazing the edge. During practice, adjust your vision by combining the wheel position and the angle of the car body. When there's no car around, ask someone to help measure and confirm the accuracy. Don't overlook blind spots for safety. Drive slowly and observe the surroundings more to avoid accidents.

During my driving lessons, the instructor emphasized using the wiper point to gauge 30 centimeters—aligning that raised part with the roadside line makes the operation straightforward and efficient. However, reference points may vary across car models, so it's advisable to conduct a quick test in your own vehicle first. For example, after positioning the wheels against the curb, glance at the wiper's position to note it down, ensuring greater accuracy during the actual test. Avoid over-reliance on a single method; integrate the use of rearview mirrors or body lines as well. Practice diligently during training sessions to build familiarity, ensuring smooth and confident performance when it counts.
