How Effective Are Repeat Intoxicated Driver Laws?

Research has shown that driver-licensing sanctions have a significant impact on impaired driving in general. Licensing sanctions imposed under State administrative license revocation systems (not the criminal justice system) have resulted in reductions in alcohol-related fatalities of between 6% and 9%. Although many repeat intoxicated drivers continue to drive without a license after their license has been revoked, studies have shown that those who drive tend to drive less frequently and more carefully. For further information about licensing sanctions, see NHTSA's Traffic Safety Facts-Administrative License Revocation.

Additional sanctions including a variety of vehicle sanction programs, have been applied successfully to deter repeat DWI offenses. California's vehicle impoundment program resulted in substantially fewer subsequent offenses. One-third of all driving-while-intoxicated (DWI) or driving-under-the-influence (DUI) arrests each year involve drivers convicted previously of DWI/DUI.
