The Intoxicated Driving Program (IDP) is a special unit within the NJ Department of Health and Senior Services’ Division of Addiction Services whose function is to carry out the mandate of the Legislature that defendants convicted of DUI and similar drug and alcohol offenses receive an evaluation, treatment and educational services. In this regard, the IDP oversees the operation of various Intoxicated Driver Resources Centers (IDRC) around the state. In New Jersey, every person convicted of a DUI must participate in a program of education provided by an approved IDRC. The required period of detention in an IDRC will depend on a number of factors, including whether the DUI is a first or subsequent offense, and is set by the judge during the sentencing phase of a DUI case. Defendants must pay fees for IDRC services, and failure to comply with the program requirements may result in an indefinite suspension and possible jail time.
