How to adjust for consistently crossing the line on the last curve of an S-turn?
2 Answers
The adjustment method for the last curve of an S-turn is as follows: 1. Before entering the curve, slow down in advance and follow the principle of taking the outer line. Choose the route with the largest turning radius as much as possible. For example, if preparing to turn left, keep the vehicle to the right. 2. When the left front corner touches the right sideline, turn the steering wheel one full turn to the left, keeping the left front corner aligned with the right sideline. 3. After completing the right line of the first curve, keep the steering wheel steady. When the right front corner touches the right sideline, straighten the steering wheel. 4. When the left one-third of the engine hood touches the left sideline of the right turn, turn the steering wheel one full turn to the right. 5. After the vehicle exits the curve, align the front of the car with the S-turn exit, straighten the steering wheel, and continue forward to exit the curve test area. 6. Avoid turning the steering wheel too sharply; generally, turn one full turn and then observe and adjust as needed.
Last time I took the driving test for Subject 2, I kept running over the line at the end of the S-curve. Later, I realized the key is to control the speed and steering wheel properly. The speed must be as slow as a snail crawling, giving you enough time to adjust the direction. When exiting the curve, keep an eye on the rearview mirror to monitor the distance between the rear wheel and the boundary line. If you feel like you're about to cross the line, turn the steering wheel half a turn in the opposite direction, and then straighten it once the car is aligned. During practice, I specifically asked the instructor to place a few markers at the last curve—using these markers as reference points significantly improved my success rate. Remember not to turn the steering wheel too much; keep each adjustment within 15 degrees to avoid overcorrection. After practicing like this for three days, I stopped running over the line and passed the test on my first attempt.
