How to judge the distance between vehicles on both sides while driving?

Here are the methods to judge the left and right vehicle distances while driving: 1. You can judge through the rearview mirror, where you can observe the distance between your car and the lane markings on both sides. 2. Judge by using reference objects. Adjustment method for left and right vehicle distances when moving forward: Adjusting while moving forward is very simple—just steer towards the side where the distance is larger. 3. Adjustment method for left and right vehicle distances when reversing: Check the left and right distances through the rearview mirror. If the distance on the left is too large, you can turn the steering wheel to the left for adjustment; if the distance on the right is too large, turn the steering wheel to the right. When adjusting, make sure to make fine adjustments, and the steering wheel's turning range must not be too large.

Having driven for over a decade, I've concluded that the most practical method is observing the rearview mirror position. Before changing lanes, make it a habit to glance at the side mirrors. If the following vehicle fills the entire mirror surface, it means they're right on your tail; if it only occupies half the mirror, there's at least a 20-meter gap; when it appears as a tiny dot in the mirror, changing lanes is completely safe. Additionally, during city traffic jams, I like to monitor the front wheel position of adjacent cars: if half the wheel is obscured by your own car body, it indicates close proximity - avoid sudden steering; when the entire wheel is visible, there's at least a meter's clearance. Always adjust your mirrors properly to eliminate blind spots - these are hard-earned lessons learned through bitter experience.

When driving, I rely more on visual reference points. The line directly in front of the steering wheel is crucial: if the left lane line extends to the lower left corner edge of the windshield, it means the car is centered; then look to the right—when the curb aligns with the right wiper node at the front of the car, the wheels are only thirty centimeters away from the curb. Don’t idle at red lights either; glance at the position of the car next to you: if the door handle of the adjacent car is level with the lower edge of your window, the gap between the two cars is enough for a bicycle to pass. On the highway, when changing lanes, the car behind must be fully visible in the rearview mirror to be considered safe; otherwise, don’t move. If the seat is adjusted too high, these reference points will change, so it’s recommended to practice a few times in an open area.

As a novice driver, my biggest fear was scratches and dents, so I developed a simple method: keeping the lane lines at fixed positions in my field of vision. When driving straight, I align the left lane line to extend from the 9 o'clock position of the steering wheel and the right lane line from the 3 o'clock position. Judging distances in the rearview mirror is even simpler—when the following car occupies one-third of the mirror, it's safe to change lanes; if it takes up half, proceed with caution. When encountering oncoming traffic on a narrow road, first reduce speed and observe the direction of the other car's tires: if the tires are angled toward your side, even if the distance is close, there's no need to worry, as it means the other driver is yielding; if the tires are pointed straight ahead, you should stop immediately.
