What is the distance to judge the rear car by the rearview mirror?
1 Answers
Rearview mirrors can judge the distance of the rear car to be between 5 to 25 meters. Judging distance with the left rearview mirror: The outer quarter of the left rearview mirror is the danger zone, while the inner three-quarters is the safety zone. When the rear car is in the safety zone of the rearview mirror and positioned to the right, it indicates a significant distance between the two cars, allowing for normal lane changes. When the rear car is in the center of the rearview mirror, it means the two cars are about 15-20 meters apart, and lane changes or other maneuvers can still be performed. When the rear car is close to the outer quarter of the left rearview mirror, it indicates the two cars are about 5 meters apart, and caution is needed when turning. If the rear car's body enters the danger zone on the left, turning or other maneuvers should not be performed. Judging distance with the right rearview mirror: When the rear car occupies a quarter of the right rearview mirror and the entire car is visible, the two cars are about 25 meters apart. When the rear car occupies a third of the right rearview mirror, the distance is about 15 meters, and lane changes can still be performed. When the rear car's image occupies half of the rearview mirror and the entire car is visible, the distance is about 10 meters, and turning can be done if safety is confirmed. If the rear car occupies half of the right rearview mirror and only half of its body is visible, the distance is too close, and lane changes are not recommended.
