DUI/DWI offenders are usually required to enroll in a specific number of hours either in counseling, meetings or a drug or alcohol rehabilitation program. Each state has its own requirements when it comes to retribution for the DUI/DWI offender. Offenders who are regarded as low to moderate DUI/DWI offenders will typically be required to participate in some form of group counseling or therapy. These are sometimes referred to as "Level I & Level II Alcohol Classes". These group meetings are typically held by a professional in the field of addiction recovery or a person with long-term sobriety involved in the Alcoholics or Narcotics Anonymous groups. DUI/DWI offenders considered to be serious offenders will likely have to serve jail time at a minimum before beginning their assigned counseling or alcohol treatment program.
