How to Find the 30cm Distance on a Slope?
4 Answers
Methods to find the 30cm distance on a slope: 1. Observe the position of the hood. When the right front corner of the hood aligns with the roadside line at one-third of its length, the distance between the car body and the roadside line is exactly 30cm; 2. When the raised part of the windshield wiper aligns with the right roadside line, the distance is approximately 30cm; 3. Look at the right front door handle and observe it in the right rearview mirror. If the right front door handle is tangent to the right roadside line, the distance is just right. The slope start is part of the field test in the second subject of the driver's license test, which involves starting a vehicle parked on a steep slope. Other test items in the second subject include parallel parking, curve driving, right-angle turning, and reverse parking.
I've taught many students how to park on a slope, and finding the 30 cm distance isn't difficult—it mainly relies on reference points on the car. For example, before getting in, adjust the seat and mirrors so that the raised part of the right wiper aligns with the line on the right side of the slope. This way, the wheels will generally stay within 30 cm. During the test, exceeding 30 cm will result in point deductions, so practice aligning with reference points often and slightly turn the steering wheel to the right to keep the car straight. Don't worry about speed; maintain a steady pace when going uphill, and lightly tap the brake when parking to confirm the position. If the reference point isn't accurate, try a different spot on the wiper—each car may vary, so pre-adjustment is crucial. Don't forget to use the mirrors to check if the tires are close to the line; 30 cm is roughly this width. With enough practice, you'll develop a feel for it. The key is to simulate slope parking frequently.
When I first started learning to drive, I often struggled with the 30cm point on the slope. Later, I found a simple trick: align the raised part on the right side of the car hood with the roadside line. The test requires this distance to be no more than 30cm, and deductions are strict, so careful alignment is crucial. Gently steer the wheel to the right without abrupt movements, and maintain a moderate speed when ascending the slope. An extra tip: practice on an open area by drawing lines to simulate the slope, measure the exact 30cm position, and use the rearview mirror to check the tire gap for confirmation. If alignment feels off, it might be due to improperly adjusted seating—test your seating position beforehand. A few more practice runs will help you memorize the spot. Nervousness can lead to mistakes, so staying relaxed makes success easier.
Finding the 30 cm mark on a half slope can be achieved by using reference points on the car. I align the right corner of the hood with the white line on the roadside, or observe the edge of the dashboard. The test requires the wheels to be within 30 cm of the line to avoid point deductions. Slightly adjust the steering wheel to the right without overcorrecting, and maintain a steady speed when going uphill. After stopping, lightly tap the brakes to confirm if the point is correct. More practice can improve accuracy, and safety is also important.
