Both the novice and the old drivers need to make reasonable judgments on the car distance when driving. On the one hand, we can ensure the safety of our vehicles. In addition, we can also grasp the distance when parking and find a suitable and safe parking place. How to determine the distance between cars? Here are some simple ways to use judgments. First, how to determine the parking distance when you encounter a traffic light (you are a head car). When we were headlighted, we encountered a traffic light. When we judged the parking distance, we could see through the window that the stop line and the corner of the car were about 5 centimeters. At this time, parking can ensure that the vehicle is aligned with the parking line. Be sure to control this distance. Otherwise, if the distance is less than 5 cm, it is easy to exceed the parking line. Second, how to determine the distance behind the car when changing over the lane. When you need to go overtaking, you can judge the distance by this way: Determine the distance by the car shadow in the rearview mirror. (1) In the rearview mirror, the whole car can be seen, the distance is generally 3M, (2) the car shadow has two-thirds of the area in the rearview mirror, the distance is 5M; (3) in the rearview mirror The car's shadow was reduced to one-half when the car distance was 9M; (4) When the car shadow was one-third, the car distance was 12M. Although these data are based on experience, they still have a certain degree of accuracy. If you do not have a vehicle distance confirmation line during driving, you can use this aspect to make basic judgments. Third, how to determine the distance between vehicles when traffic jams. When traffic jams, it is generally appropriate to control the distance from the car to about 2M. If it is too close, it is prone to rear-end collision. If it is far from this distance, other vehicles can easily insert it. So how to master this distance? The judgment can be made by the position of the front of the own vehicle to the position between the front bumper at the rear of the vehicle. In general, the distance when the front bumper was just seen is 1M. The distance between the lower edge of the front bumper is 2M, and the distance between the lower edge of the front tire and the front wheel is 3M. According to these basic judgments, the distance to the car can be controlled. These methods are simple and practical, and they are relatively easy to operate.
