Driver's license point systems vary by state. Each individual state department of motor vehicles or state motor vehicle code has to be consulted to determine how many points it assigns for speeding violations.
States often apply varying amounts of points depending on how far over the speed limit the vehicle was going. For example, in Tennessee, only one point is assigned if the vehicle is traveling at 5 mph or less over the speed limit, but eight points are assigned if the vehicle travels in excess of 45 mph over the limit. Points are also often multiplied for speeding in a construction zone or while driving a commercial vehicle.
