Is the 30cm in straight-line driving referring to the sideline or deviation?
2 Answers
Straight-line driving 30cm refers to the left and right deviation. The following is the relevant introduction to straight-line driving: 1. Rules: After the new regulations, straight-line driving has become more stringent, requiring the steering wheel swing amplitude to be no more than 5 degrees. Straight-line driving must reach 100 meters, and the distance between the front and rear wheels and the sideline must not exceed an error of 30 centimeters, otherwise it will be deemed unqualified. 2. Precautions: Operate the steering wheel by pulling with one hand and pushing with the other. During the vehicle's movement, slightly adjust the steering wheel, each time adjusting a little in the opposite direction of the vehicle's deviation. Basically, as long as the left and right amplitude does not exceed 5 degrees, there will be no problem.
After driving for so many years, I've noticed that deviating 30 cm in a straight line is quite common, especially among new drivers. Many people think 30 cm is negligible, but in reality, shifting this distance from the center line on a lane already brings you dangerously close to the edge. If another car passes by closely, it could lead to an accident. I remember one rainy day when I wasn't paying full attention, and my car drifted nearly 30 cm without me realizing it. A truck zoomed past me, giving me quite a scare. Since then, I've made it a habit to frequently check my rearview mirror to monitor my lane position. If you're driving an automatic car, the system might help a bit, but with a manual, it's all up to you. When practicing, find an empty road to slowly adjust your steering and aim to keep deviations within 15 cm—that's the ideal. Driving isn't just about looking ahead; sensing your car's position is crucial. Even a slight lapse can lead to drifting, and compromising safety just isn't worth it.
