You should allow 10 feet for every 10 miles per hour. So if you are traveling at 70 mph, you should safely leave at least 70 feet between you and the car in front of you. Heavier vehicles, and those pulling trailers, need longer distances. Rule of thumb, if you know you can't possibly stop your car within the distance you are following another, then you are w-a-y too close. The car in front of you will not travel any faster by you trying to drive up its tailpipe.
