Intoxicated Driver Program (IDP)

The Intoxicated Driver Program (IDP) was created in 1982 to reduce the number of impaired driving related crashes and related injuries, deaths, and property damage. There are two parts to the program, an assessment and a driver safety plan.

IDP assessment

Anyone convicted of a operating while intoxicated (OWI) related offense is required to contact the approved assessment facility for their county of residence within 72 hours of conviction or immediately upon receipt of an order from the Department of Transportation (DOT).

The assessment evaluates an individual's alcohol and/or other drug use habits.  Assessors use the Wisconsin Assessment of the Impaired Driver (WAID) to determine whether drivers need education, treatment, or both to reduce the likelihood they will drive impaired in the future.

IDP driver safety plan

A driver safety plan is prepared following the assessment.  Completion of the driver safety plan is required to have driving privileges restored.

Find IDP county coordinators and assessment facilities

IDP assessments are done in the county in which the driver lives.  County-designated IDP assessment agencies are responsible for assessing drivers.  The Department of Health Services (DHS) maintains a directory of all county IDP coordinators and county-designated assessment facilities.  

Resources for IDP assessors, supervisors, coordinators

DHS maintains a directory and library of forms for IDP.

The following is a list of rules and regulations.

The UW-Madison Division of Continuing Studies offers approved training for IDP assessors, supervisors, and coordinators. For more information on training opportunities, please contact Kristi Obmascher at 608-262-8971.
