How to check if the front wheels are crossing the line in an S-curve?
2 Answers
When entering the curve, try to stay close to the right sideline, as the first turn is to the left. When the left front corner of the car approaches the right sideline, turn the steering wheel one full turn to the left. After turning left one full turn, check the left rearview mirror to observe the distance between the rear body and the left sideline. Adjust the steering to maintain a distance of about 30 centimeters. When reaching the junction of the curves, straighten the steering wheel and proceed straight. At this point, check the small mirror on the right front corner of the car to ensure the body maintains a distance of about 30 centimeters from the right sideline.
As a novice who hasn't been driving for long, I used to worry about the front wheels crossing the line when taking S-curves right after getting my license. My method was to slow down to 10-20 km/h, which made it easier to assess the situation. When entering a curve, I'd instinctively tilt my head to glance at the front wheel position through the side window—checking the right wheel for right turns and the left wheel for left turns. Feeling that the wheel edge was about a fist's distance from the roadside line meant it was safe. If the distance was too close or the wheel was directly aligned with the line edge, it indicated an imminent line crossing, prompting me to quickly adjust the steering wheel. My instructor reminded me not to fixate on the windshield but to scan the surroundings more effectively. Crossing the line isn't just a test failure—on the road, it risks scraping tires or curbs, which is no small hazard. So, I recommend beginners practice simulated curves in parking lots, using cones to train their judgment. With time, it becomes easier, but remember: maintaining a steady speed is key.
