You're 16 or 17 And Still Tail-Gating

Tail-Gating (aka following too closely) is the #1 cause of accidents for 16 and 17 year old. Although the 2-second rule is generally accepted for most drivers it is now recommended that those in this age group should follow the 3-second rule. Why?
Because you don't have the time behind the wheel, knowledge or experience yet.
Rule: Pick a spot where the car in front of you is, start counting, 1-1,000, 2-1,000, 3-1,000. If you passed that spot before you got to 3-1000 then you were tail-gating.
