How to Judge Left and Right Distance for Beginners on the Road
3 Answers
Beginners on the road can use the positions of the left and right windshield wipers to help judge the distance on both sides. When the protruding node of the left wiper aligns with an object on the ground, the left wheel will run over that object while moving. When the line of sight intersects with the right wiper and the target, the right wheel will run over that target. Judgment of the left wheel position: It is necessary to know where the left wheel will run over to avoid the tire pressing on solid lines or evading potholes and stones on the road. When the line of sight aligns the protruding node of the left wiper with an object on the ground, the left wheel will run over that object while moving. Judgment of the right wheel position: When the line of sight intersects with the right wiper and the target, the tire will run over that target.
I was also very afraid of scratches when learning to drive. Here are some practical tips: When driving, align the far right side of the steering wheel with the center of the lane line, which basically ensures the wheels stay within the lane. To judge the distance between the car body and the roadside, the most accurate method is to observe the side mirrors: when you see the edge of the right mirror just overlapping with the curb, it's usually about 30 cm away. When passing through a narrow lane, focus on the overlap point between the left A-pillar and the road boundary line—if they overlap, it means you won't scrape. Practice a few times in an open area with an old car, get out to observe the trajectory, and build muscle memory. Remember that reference points vary with different car models, so it's best to readjust when switching cars. If you're really unsure, slow down—even experienced drivers learned from scratches.
As a decade-long driving instructor, I recommend beginners develop three reference systems: First, the wiper node – when the right node aligns with road markings, the car body maintains a 60cm distance. Second, to determine left wheel position, use the vertical extension line above the left footrest. Third, the mirror rule – when 2cm of curb shows at the bottom of the right mirror, tires are 20cm from the roadside. Special tip: During narrow-road encounters, avoid fixating on obstacles; looking ahead improves steering control. When references are unclear (night/rain), allow extra 10cm margin. Develop the habit of verifying distances after parking to gradually build spatial awareness.
