Http: / / www.zsnews.cn the principle of two seconds to choose the side of the road surface or a fixed reference, if the vehicle in front and your car through the reference time interval in more than two seconds, then explain the basic right chevron . This is because cars usually speed around the same time in the same braking conditions have basically the same as the braking distance. A two-second intervals before and after the vehicle will be able to ensure an effective brake.
driving rain rain, a relatively wet and slippery roads, the safety distance between vehicles at this time would require more than 0.5 ~ 1 times, you can have enough braking distance. Highway
highway safety distance between vehicles should be based on the relative speed you should be. Speed under normal circumstances as a reference, that is, speed 80km / h, while maintaining a safe distance from the best in the 80m or so.
exceptional circumstances when the vehicle load or a long bus厢体, security should also be a corresponding increase in the distance.
attention to the vehicle in front with the car, we must always pay attention to the instructions in front of the vehicle lights, such as brake, turn signal, and timely response under the circumstances. If overtaking
a timely manner as conditions permit, select the appropriate time to go beyond the vehicle in front to minimize the situation with the car.

在中国的高速公路上行车，前后车的车距应是多少？有法律依据或条例的规定吗？如果有法律依据，这个法律的名称是什么？是何时制定的？

回答:
《中华人民共和国道路交通安全法实施条例》　　第八十条 机动车在高速公路上行驶，车速超过每小时100公里时，应当与同车道前车保持100米以上的距离，车速低于每小时100公里时，与同车道前车距离可以适当缩短，但最小距离不得少于50米。
　　第八十一条 机动车在高速公路上行驶，遇有雾、雨、雪、沙尘、冰雹等低能见度气象条件时，应当遵守下列规定：
　　（一）能见度小于200米时，开启雾灯、近光灯、示廓灯和前后位灯，车速不得超过每小时60公里，与同车道前车保持100米以上的距离；
　　（二）能见度小于100米时，开启雾灯、近光灯、示廓灯、前后位灯和危险报警闪光灯，车速不得超过每小时40公里，与同车道前车保持50米以上的距离；
　　（三）能见度小于50米时，开启雾灯、近光灯、示廓灯、前后位灯和危险报警闪光灯，车速不得超过每小时20公里，并从最近的出口尽快驶离高速公路。

雨天行驶 雨天，道路相对湿滑，此时的安全车距就需要比平时多出0.5~1倍左右，可以有足够的制动距离。
高速公路 高速公路上的安全车距应该根据你的车速相对应。通常情况下可以车速作为参考，即车速80km/h，则安全距离{zh0}保持在80m左右。
特殊情况 当遇到载重车辆或者是长厢体的公交车，安全距离也应该相应增加。
注意前车 跟车时，要时刻注意前方车辆的信号灯指示，如制动、转向灯等，并根据情况及时做出反应。
适时超车 如果条件允许，选择适当的时机超越前车，尽量减少跟车状况出现。
