People in Montclair with DUI/DWI are often court ordered to participate at an alcohol or drug rehab center, usually when they are first time offenders and in lieu of other stiff penalties. While being convicted of a DUI/DWI in Montclair usually comes with large fines and even incarceration in some cases, the criminal justice system is sometimes more inclined to help rehabilitate the particular person rather than punishing them. Letting individuals with DUI/DWI to take part in a drug and alcohol rehabilitation center as an alternative to other forms of punishment has shown to be effective in keeping people in Montclair out of the criminal justice system because of DUI/DWI in the future.
