When driving at night, you can judge the distance between cars by determining the position of the vehicle, the distance to the car in front, and the distance to the car behind. The following is a detailed introduction on how to judge the position of the vehicle at night: Judging the position of the vehicle: (1) Determine the position of the roadside in the windshield by using the rearview mirror. (2) Determine the position of the right wheel and the vehicle by the relative position of the right wheel to the ground. Judging the distance to the car in front: (1) Judge the distance to the car in front by observing the relative position of the windshield to the bumper of the car in front: When the upper edge of the bumper of the car in front is seen from the lower edge of the windshield, the distance between the two cars is about one meter. When the lower edge of the bumper of the car in front is seen from the lower edge of the windshield, the distance between the two cars is about two meters. When the lower edge of the rear tire of the car in front is seen from the lower edge of the windshield, the distance between the two cars is about three meters. (2) By observing the position of the ground in the left rearview mirror: The horizontal line relative to the ground displayed at the lower edge of the left rearview mirror is the position of the front of the car. Judging the distance to the car behind: (1) Judge the distance to the car behind by observing the proportion of the car's shadow in the rearview mirror: When the shadow of the car behind occupies the entire rearview mirror, the distance is about 3 meters; when the shadow occupies two-thirds of the rearview mirror, the distance is about 5 meters; when the shadow occupies half of the rearview mirror, the distance is about 9 meters; when the shadow occupies one-third of the rearview mirror, the distance is about 12 meters. (2) Judge the distance to the car behind by looking through the lower edge of the rear window windshield in the interior rearview mirror: If the upper edge of the headlights of the car behind is seen, the distance from the rear trunk to the car behind is about three and a half meters; if the junction of the engine hood and the front windshield of the car behind is seen, the distance from the rear trunk to the car behind is about one meter; if the horizontal one-third of the front windshield of the car behind is seen, the two cars are extremely close.
