Safe driving as discussed in previous posts is important and keeping a safe driving distance is one of components of safe driving.
There is so called “three-second rule” which helps you to determine safe distance from the car ahead of you.
Of course, first, the distance changes at different speeds. To determine the safe driving distance, first select a fixed object on the road ahead such as a sign, tree or overpass. When the vehicle ahead of you passes the object, slowly count “one one thousand, two one thousand, three one thousand.” If you reach the object before completing the count, you’re following too closely. Make sure there are three seconds between you and the car ahead gives you time and distance to respond to problems in the lane ahead of you.
Second, the distance changes at different weather conditions and daylight. In night or when it is rainy or foggy, the three-second-rule should be doubled to the six-second-rule.
||Safe Interval Should Be:
||For These Conditions:
||37 ft. per second
||52 ft. per second
||66 ft. per second
||81 ft. per second
||96 ft. per second
||111 ft. per second
