The National Transportation Safety Board is making hard-core drunk driving one its top priorities. Hard-core drunk drivers are drivers who get on the road with a blood alcohol content of 0.15 percent or higher, or offenders who have been arrested multiple times for DUI or drunken driving within the last 10 years. As a part of its efforts, the National Transportation Safety Board is lobbying states to adopt its 11 point safety program to reduce the risk of hard-core drunk drivers on the road.
