Which point on the wiper blade to look at for 30 centimeters?
2 Answers
For 30 centimeters, look at the position between the root of the right wiper blade and the washer nozzle. Other reference points for judging 30 centimeters: 1. Look at the engine hood: When one-third of the front of the car covers the right lane edge line, you can stop; 2. Look at the right door handle: Observe the right door handle through the right rearview mirror, and when it aligns with or just touches the roadside edge line, you can stop. Techniques for parking 30 centimeters from the edge: 1. Find the right position to start parking by looking at the one-third point of the car hood; 2. Observe the distance between the right side of the car body and the road edge, and make slight adjustments to the steering wheel from left to right; 3. When the right front door handle is about to align with the roadside, quickly straighten the car body; 4. Look at the right front door handle from the right rearview mirror, and when it is tangent to the edge line, stop, shift to neutral, pull the handbrake, release the clutch and brake, check the left rearview mirror to ensure safety, unbuckle the seatbelt, and exit the car.
I remember during my driving test, the instructor taught me to sit up straight, look out, and use the highest protrusion point of the windshield wiper to align with the edge of the roadside white line. When that point just touches the top of the line, the distance between the car body and the line is approximately 30 cm, which is particularly useful in Subject 2's slope parking and parallel parking. I practiced repeatedly for several weeks, each time adjusting the seat to a fixed height to ensure a consistent view. Different car models have slight variations in wiper positions—for example, the point on my car is a bit to the left, so I always test it once after getting in the car to locate the spot. During the test, I passed in one go thanks to this technique, and I still use it in daily parking to avoid scratches. The point can become blurry when the wipers age or during rain, so regular maintenance is necessary—don’t rely solely on this method. Practice is key; beginners can master the trick after a few tries.
