Driving safety distance

Judging the distance between the front end of the car and pedestrians

The approximate distance between pedestrians and vehicles can be judged by the different parts of pedestrians blocked by the front of the car. Take a car as an example. Suppose the height of pedestrians is1.8m. ..

1. When the driver sitting in the driver's seat can see the feet of pedestrians in the car, the distance between the front of the car and pedestrians is about 5.5 meters.

2. When the driver can just see the knees of the pedestrians in the car, the distance between the front of the car and the pedestrians is about 2.2 meters.

3. When the driver can see that the hip of the pedestrian can just be covered in the car, the distance between the front of the car and the pedestrian is about 0.3 meters.

Judging the distance from the front car (taking SUV models as an example)

1. When looking at the upper edge of the front bumper from the lower edge of the windshield, the distance between the front car and the rear car is 0.5m If the front car is a car, it is at this distance.

2. When looking at the lower edge of the front bumper from the lower edge of the windshield, the distance between the front car and the rear car is1.2m. If the front car is a car, it is about 2m.

3. When you see the lower edge (or ground) of the front car rear tire from the lower edge of the windshield, the distance from the front car is about 3 meters.

When waiting for the red light, it is best to see the lower edge of the bumper of the front car. When parking on both sides of the road, the best position is to see the upper edge of the bumper of the front car.

The right rearview mirror judges the distance behind the vehicle.

1. The rear car occupies half of the rearview mirror, and only half of the body can be seen. At this time, the rear car is very close to your car, so keep driving in the existing lane and don't turn.

2. The rear car occupies half the area of the exterior rearview mirror, and you can see the whole car. At this time, the distance between the rear car and your car is about 10 meter, so you can only turn on the lights when the speed is slow.

3. The rear car occupies the area of the exterior rearview mirror13, and you can see the whole car. Explain that the distance between the rear car and your car at this time is about 15 meters, and you can turn.

The left rearview mirror judges the distance behind the vehicle.

1, the rear car body has entered the dangerous area on the left side of the dashed line of the rearview mirror, indicating that the rear car is very close to your car, so you can't turn at this time.

2. The left side of the rear car body is close to the dividing line between the safe area and the dangerous area. At this time, you should be vigilant, but it is safe to turn on the turn signal.

3. The rear car is in the safe area and located in the center of the rearview mirror, which means that the distance between the rear car and your car is15-20m, and you can turn normally.

The inside rearview mirror judges the distance behind the car.

You can see the lower edge of the tire of the rear car, and the distance between the rear car and the front car is about 20 meters. At this distance, the safe speed is about 25 km/h. If you see the upper edge of the rear headlights, the rear trunk is about three and a half meters away from the rear car. If you see the joint between the rear hatch cover and the front windshield, the rear trunk is one meter away from the rear car. If you see that the front windshield of the rear car is one third of the level, it is basically open.
