Use your rear view mirror to determine the distance between cars, practical to the point of explosion, must learn!

I. Judging the distance between the front of the car and the pedestrian

Using a car as an example, assuming a pedestrian height of 1.8 m

1. When you can just see the feet of the person walking in front of the car, the distance between the front of the car and the pedestrian is 5 meters at this point.

2. When you see the front end of the car raised to the knee height of the pedestrian, the distance between the front end of the car and the human body is 2.2 meters.

3. When you see the front end of the car raised to the lower end of the human hip, the distance between the front end of the car and the human body is 0.3 m.

II. Judging the distance to the car in front

Take the SVU model as an example

1. When you see the upper edge of the bumper of the front car from the lower edge of the windshield, the front car is 0.5m away from the rear car at this time. If the car in front is a sedan, it is at this distance.

2. When you see the lower edge of the bumper of the front car from the lower edge of the windshield, the front car of this car is 1.2 meters away from the rear car. If the car in front is a sedan, it will be about 2 meters.

3. The distance to the car in front is about 5 meters when you see the lower edge of the rear tire of the car in front (or see the ground) from the lower edge of the windshield.

Third, the right rear view mirror to determine the distance behind the car

1. The rear car occupies half of the rear view mirror area and only half of the body is seen. At this point, the car behind you is so close to your car that you should stay in your existing lane and not swerve.

2. The rear car occupies half of the area of the outside rear view mirror and can see the whole car. At this point, the car behind you is about 10 meters away from your car, and you can only operate the turn after hitting the lights at a slower speed.

3. The rear car occupies 1/3 of the area of the outside rear view mirror and can see the whole car. It means that at this point the rear car is about 15 meters away from your car and can perform a steering operation.

Fourth, the left rear view mirror to determine the distance behind the car

1, the rear car body has entered the danger area on the left side of the dashed line of the rearview mirror, indicating that the rear car and your car distance is very close, at this time can not turn.

2, the left side of the rear car body has been close to the boundary between the safety zone and the danger zone, then you should be more alert, but at this time to hit the lights to turn is still safe.

3. The rear car is in the safety zone, in the center of the rearview mirror, indicating that the rear car is 15-20 meters away from your car and can operate the steering normally.

V. Rear view mirror in the car to determine the distance behind the car

The lower edge of the rear car's tyre was able to be seen, and at this point the rear car was about 20 metres away from the front car. At this distance, the safe speed is about 25 km/h. If the upper edge of the rear headlights is visible, the rear trunk is about three and a half metres from the rear.

If you see the junction of the rear compartment lid with the front glass, the rear tailgate is one metre from the rear. If you see the horizontal third of the front glass of the rear car, you are basically leaning up.
