How much should the car head enter before straightening the direction during lane change in Subject 3?

During a lane change in Subject 3, the steering wheel is generally turned 10 degrees, and the direction can be straightened once the car body enters the lane. Below is relevant information about the driver's license test: 1. Introduction: The driver's test is a qualification examination organized by the Vehicle Management Office of the Public Security Bureau. Only by passing the driver's test can one obtain a driver's license and legally operate a motor vehicle. 2. Content: The motor vehicle driver's test is divided into the subject of road traffic safety laws, regulations, and related knowledge (also known as the 'theory test', referred to as 'Subject 1'), the subject of field driving skills (commonly known as 'pole test', referred to as 'Subject 2'), and the subject of road driving skills and safety and civilized driving common sense (commonly known as 'road test', referred to as 'Subject 3'). The test content and passing standards are uniformly set nationwide, with corresponding test items specified according to different types of vehicles eligible for driving.
Back when I was taking my driving test, the instructor always emphasized smooth lane changes, especially for the third part of the exam. He said that when about half of the car's front has entered the new lane, you should start gradually straightening the steering wheel so that the wheels can turn smoothly without causing too much body sway. Thinking back to my practice sessions, there was a time when I straightened too early and the car body crossed the line, resulting in an immediate deduction by the examiner. If done too late, the car might jerk or lurch, startling the vehicles behind. The instructor also reminded me to first check the rearview mirror to confirm safety, signal for at least 3 seconds, maintain a steady speed, and avoid sudden acceleration or braking. It took me over a dozen practice runs to get the hang of it, mainly relying on feel to judge the lane width and position. Overall, the key during the test is to stay calm and not rush—safety comes first. With enough practice, it becomes second nature, and the same caution is needed when driving on real roads after passing the test.
When I first started learning to drive, I was particularly confused about the timing of straightening the wheel after changing lanes, always afraid of making mistakes. Later, my instructor taught me a trick: gently straighten the wheel when about half of the car's front has completely entered the new lane, which allows the car to move in smoothly. During the test, the examiner pays close attention to whether the steering is smooth. When practicing on my own, I tried various angles. For example, straightening the wheel too early would cause the car to shake, while doing it too late would make it feel like a sharp turn. Combining the use of rearview mirrors to check blind spots and monitoring the speedometer to control speed is also crucial; otherwise, the overall score would be low. After practicing several times, I got the hang of it—focusing on the lane rather than counting seconds. Developing this habit made passing the third driving test easy, and now my daily driving is much smoother.
After driving for so many years, changing lanes and straightening the wheel is a basic skill. I usually start straightening the wheel when about 40-50% of the car's front has entered the new lane. This way, the car body glides smoothly without bumps or sharp turns. In the driving test (Subject 3), this method is recommended because it demonstrates safety awareness—straying over the line or hesitating will result in penalties. In daily driving, I also pay attention to speed and distance. For example, on highways, straightening should be lighter and earlier to avoid sudden movements that might affect other drivers. With enough practice, you can develop this sense of control, ensuring safety and peace of mind.
