What is the appropriate value of vehicle distance and speed?

When the speed of the motor vehicle is 60 kilometers per hour, the distance between vehicles should be more than 60 meters; At a speed of 80 kilometers per hour, the distance between vehicles is more than 80 meters, and so on.

1. Safe vehicle distance.

Safe distance is the distance between the vehicle behind and the vehicle in front of it in order to avoid an accidental collision with the vehicle in front. There is no absolute numerical concept of safety distance, it depends on the situation. Generally speaking, the faster and heavier the vehicle, the longer the interval required for the safety distance.

The safe distance can also be affected by many other factors, such as weather conditions and light intensity.

Driver vision, braking equipment, road conditions, etc.

2. Theory**.

According to the laws of mechanics, a vehicle will continue to move forward for a certain distance from the time it is in motion to complete rest. If the car is too close to the vehicle in front, it is very easy to collide with the vehicle in front and cause a rear-end accident. In order to ensure that the vehicle behind does not collide with the vehicle in front of it, no matter how extreme the situation, the vehicle behind needs to always maintain a certain distance from the vehicle in front of it so that there is enough braking space (including braking time, braking distance, etc.) in case of emergency.

3. Measurement standards.

There is no absolute standard for safe distance, only a dynamic standard. The most direct and important factor influencing the safe distance is the speed. When the speed of the vehicle increases, the required braking force, braking distance, and the distance the vehicle travels at the original speed during the reaction time all increase accordingly.

Maintaining a safe distance requires speed control.

Fourth, refer to the speed.

High-speed driving, that is, when the speed is above 100kmh, the safe distance between the vehicles is more than 100 meters.

Fast driving, that is, when the speed is more than 60km h, the safe distance is numerically equal to the speed; For example, the speed of the vehicle is 80 km h, and the safe distance is 80 meters.

Medium-speed driving, that is, when the speed is about 50km h, the safe car distance is not less than 50 meters.

Low-speed driving, that is, when the speed is below 40kmh, the safe distance between the vehicles is not less than 30 meters.

Turtle speed driving, that is, when the speed is below 20km h, the safe distance between the car is not less than 10 meters.

The above data mainly refers to the relevant traffic laws and regulations, both old and new.

Synthesized.

The speed of the car is 80-120 kilometers per hour, the novice on the road in the middle lane, the leftmost side is the overtaking lane, the rightmost is the emergency lane, the emergency lane is generally not allowed to drive, the emergency lane is the slow lane, and then the normal driving lane. On the highway, the speed of the car is from left to right, from fast to slow. Novices on the road speed is generally kept at 80-100, do not change lanes at will, pay attention to the trial of turn signals.

Try not to stop on the highway again, and try to keep the emergency lane as much as possible, and park in the nearest service area.

The maximum speed shall not exceed 120 kilometers per hour, the minimum speed shall not be less than 60 kilometers per hour, and the distance between the two vehicles shall be more than 100 meters. The first time you drive on the highway, keep your distance, hold the steering wheel tightly, and look straight ahead. gogo

If the motor vehicle is driving on a high speed, the distance between the vehicles should be maintained at least 50 meters or more than 100 meters due to the difference in speed.

According to Article 80 of the Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China:

When a motor vehicle is driving on a highway at a speed of more than 100 kilometers per hour, it should keep a distance of more than 100 meters from the vehicle in front of the same lane, and when the speed is less than 100 kilometers per hour, the distance between the vehicle in front of the vehicle and the same lane can be appropriately shortened, but the minimum distance shall not be less than 50 meters.

Article 80 of the Regulations for the Implementation of the Road Traffic Safety Law: When a motor vehicle is driving on a highway at a speed of more than 100 kilometers per hour, it shall keep a distance of more than 100 meters from the vehicle in front of the same lane, and when the speed is less than 100 kilometers per hour, the distance between the vehicle and the vehicle in front of the same lane may be appropriately shortened, but the minimum distance shall not be less than 50 meters.

If it is not a high speed, it is usually about 10 to 15 meters.

50m, of course, this spacing is not the spacing on high speeds.

According to the Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China, when a motor vehicle is driving on a highway at a speed of more than 100 kilometers per hour, it should keep a distance of more than 100 meters from the vehicle in front of the same lane, and when the speed is less than 100 kilometers per hour, the distance between the vehicle in front of the vehicle and the same lane can be appropriately shortened, but the minimum distance shall not be less than 50 meters. When driving in urban areas, there is no absolute standard for the distance between vehicles, and it should be judged according to the speed of the vehicle.

If the speed of the vehicle exceeds 60km h, then the distance from the vehicle is equal to the speed of the vehicle in meters; When 50km h, the following distance should be greater than or equal to 50m40km h, the following distance should be greater than or equal to 30m20km h, the following distance should be greater than or equal to 10m, and when following the car at low speed, it should be kept at the second point The lower edge of the windshield is just the visual distance to the lower edge of the bumper in front of the car, so that other cars are not easy to enter, and the front car has enough reaction distance for emergency braking. How to judge the distance of the car: The distance of the car in front can be roughly judged by observing the lowest position of the car in front that can be seen.

When the lower edge of the windshield just reaches the dividing line between the front and rear wheels and the ground, the distance between the front and rear wheels is meters. When the lower edge of the windshield just reaches the lower edge of the bumper of the front car, the spacing between the front cars is when the lower edge of the windshield just reaches the lower edge of the license plate of the front car in front of the paragraph, and the spacing between the front cars is.

When a motor vehicle is driving on a highway at a speed of more than 100 kilometers per hour, it shall keep a distance of more than 100 meters from the vehicle in front of the same lane, and when the speed is less than 100 kilometers per hour, the distance between the vehicle and the vehicle in front of the same lane can be appropriately shortened, but the minimum distance shall not be less than 50 meters; When driving in urban areas, there is no absolute standard for the distance to follow the car, and it should be judged according to the speed of the vehicle. The following distance of driving in the urban area is as follows: 1. If the speed exceeds 60kmu002fh, then the distance with the car is equal to the speed, and the unit is meters kmu002fh when the following distance should be greater than or equal to 50 meters kmu002fh when the following distance should be greater than or equal to 30 meters kmu002fh when the following distance should be greater than or equal to 10 meters.
