The advocacy group Mothers Against Drunk Driving (MADD) ranks the states in an annual report concerning how strict the DUI laws are in various states.
MADD in determining the rankings considers a number of factors, including the amount of special training officers receive in detecting signs and behaviors of drunk drivers, the required use of interlock systems, the frequency of sobriety check points and the severity of punishments for those convicted of Driving While Impaired (DWI).

All factors considered, Mothers Against Drunk Driving concluded that Mississippi has instituted policies which MADD finds to be the most beneficial in cracking-down on DUI/DWI offenders.
