What are the reasons for crossing the right boundary line during a 90-degree turn?
4 Answers
The reasons for crossing the right boundary line during a 90-degree turn are as follows: 1. Reasons for crossing the line: The speed is too fast, as excessive speed makes it difficult to control the vehicle body, leading to easily crossing the corner or line; Initial position, before turning, the distance between the vehicle body and the inner boundary line should not be too close, otherwise insufficient reserved space may cause crossing the line. 2. The correct method to avoid crossing the line during a 90-degree turn: Before entering the turn, drive close to the right side first. When the inner corner of the 90-degree turn aligns with the driver, start turning the steering wheel to the left. When the left rear wheel of the car aligns with the inner corner line of the 90-degree turn, the steering wheel should be turned to the maximum. Once the left rear wheel passes the inner corner line, begin gradually turning the steering wheel back to the right. After the steering wheel is straightened, drive out of the turn.
After driving for so many years, I've seen many people run over the right line during 90-degree turns, mainly due to poor steering technique. A 90-degree turn requires precise calculation of how much to turn the steering wheel. If you turn too early or too late, you're likely to scrape the line. A common mistake beginners make is not fixing their eyes on the reference point at the corner, resulting in delayed reaction and the wheels going out. Another issue is speed – entering the turn too fast will pull your car outward due to inertia, forcing you toward the right line. I used to do the same when I was younger, but after much practice, I learned to enter turns slowly and adjust direction by focusing on the inner corner line. Regular practice on simulated turns helps develop a feel and reduces the risk of crossing the line. Remember, safety first—always check your speed before each turn. Don’t rush to avoid tire damage or worse, a collision. Driving skills are honed over time; steady progress always pays off.
As someone who frequently instructs beginners, I find that hitting the right line during a right-angle turn is often caused by incorrect focus of vision. Some people only look at the steering wheel instead of focusing on reference points ahead, such as the corner marker, missing the optimal turning moment. Turning the steering wheel too little or too hastily causes the wheels to drift right and hit the line. Another key factor is speed—going too fast increases centrifugal force, making the car slide toward the outer line. When teaching, I emphasize slowing down before entering the turn, maintaining a speed of around 20 km/h, while simultaneously keeping an eye on the corner and gently turning the steering wheel to maintain a stable arc. If hitting the line occurs frequently, I recommend practicing in simulated scenarios, setting up a course with cones to repeatedly familiarize oneself with the steering points. After all, hitting the line during a turn not only wastes space but also increases the risk of scraping or losing control. Developing good habits will build confidence. Paying more attention during daily driving ensures safety and peace of mind.
When I first learned to drive, I often ran over the right line during 90-degree turns because I was too nervous. I would turn the steering wheel half a beat too slowly before the turn and couldn't control the speed properly. When nervous, I'd forget to check the distance to the right line, causing the wheels to slide onto the line and nearly scrape the curb. Later, I realized the key is practice—new drivers lack experience and make mistakes easily, but with more practice, you learn to time your steering correctly without hesitation. Going too fast can also push you outward and over the line, so it's best to slow down before entering the turn. Every time I crossed the line, I reminded myself to drive slower and wait until I had a clear view of the corner before acting. Now, I'm much better. Safe driving is no small matter—small mistakes can accumulate into big problems. Keep practicing to improve and drive more steadily.
