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.
