What is the reason for hitting the right boundary line during a 90-degree turn?
2 Answers
It is because the vehicle speed is too fast and the steering is applied too late. Here are the relevant details: 1. Subject 2: Subject 2, also known as the small road test, is part of the motor vehicle driver's license examination. It refers to the field driving skill test subjects. For small vehicles C1 and C2, the test items include five mandatory components: reversing into a parking space, parallel parking, stopping and starting on a slope, 90-degree turns, and curve driving (commonly known as S-turns). 2. 90-degree turn: The 90-degree turn is an assessment point in Subject 2 of the driver's test. It evaluates the driver's ability to correctly manipulate the steering and accurately judge the inner and outer wheel differences when driving through sharp turns.
I often ponder about cutting the right line when taking sharp 90-degree turns. The main issue lies in mistiming the turn entry—either steering too early or hastily turning the wheel only after the front wheels have crossed the line. We should focus our gaze further ahead, keeping the left side of the car about 30cm from the lane boundary for optimal safety. The steering wheel should be turned fully right when the left rearview mirror passes the corner apex. Pay special attention to rear-wheel tracking and the difference in turning radius—after the front wheels clear, the rear wheels will naturally pull inward, so abrupt steering will guarantee rear-wheel line violation. Always control your speed during turns; impatient drivers like me have learned the hard way that excessive speed leaves no room for subtle steering corrections. With more driving experience, you'll instinctively leave extra margin on the right side and avoid locking the steering wheel at full turn, maintaining half a turn's flexibility for adjustments.
