1.You should follow no closer then 3 seconds behind the automobile in front of you.
When the rear bumper of the car in front is even with an fixed object IE: a tar strip or sign start counting 1001,1002,when you reach 1003 your front bumpr should be adjacient to the fixed object. If you reach the fixed object before 1003 then you are following to close.This  is the new way of gaugeing following distance as the feet per miles per hour is outdated and to hard to judge distance.
2.During inclement weather and night double it to 6 seconds.Heavy rain or snow use 9 second rule.
3.when you have a tailgater following to close back off and double the safe following distance.
4.Semi's should follow the 4 second rule.
5.autos should also follow the 4 second rule when   following motocycles.
