What does 3 points on a license mean?

It all depends on what state you live in.. Each state has a different point system for their drivers licenses and normally a couple points are no big deal but they accumulate and when you reach a certain amount they will suspend your license. In most states you can elect to take traffic school or go to Traffic court and have adjudification withheld and have the point removed. You are still admitting guilt for the infraction but you will not accumulate points. Hope this helped.
