DUI/DWI offenders are typically required to participate in a specific number of hours either in counseling, meetings or a drug or alcohol rehab program. Each state has its own requirements when it comes to sentencing 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 meetings are often 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 deemed to be serious offenders will likely have to serve jail time at a minimum before beginning their mandatory counseling or substance abuse rehab program.
