What is IDIP?
The Pretrial Impaired Driving Intervention Program is established by C.G.S. § 54-56r for people charged with specified impaired-operation offenses. The program can involve a twelve-session alcohol-education component or a substance-use treatment component of at least fifteen sessions, and the court may also order a victim-impact component.
Who may be eligible?
The statute contains important exclusions involving prior program use, prior OUI-related convictions, commercial driving circumstances, and cases involving serious physical injury, subject to the statute’s terms. Eligibility must be checked against the current charge and history.
What happens after referral?
DMHAS explains that the program includes an evaluation by a substance-abuse professional. The resulting report and recommendations go back to the referring court. The court decides whether the participant will complete the education track or a treatment track and what other conditions apply.
Why does the program matter strategically?
A diversionary program can be one possible objective in an eligible case, but it should be evaluated alongside the evidence, suppression issues, DMV consequences, collateral consequences, and the client’s priorities. A program is not automatically the right choice simply because it may be available.
What should be evaluated before choosing IDIP?
Program eligibility is only one part of the decision. Before electing a diversionary route, the defense should review the traffic stop, field sobriety testing, chemical-test evidence or refusal evidence, body-camera and cruiser video when available, and any issues affecting whether the State can prove operation and impairment. The separate DMV administrative case also has its own deadlines and should not be overlooked while the criminal case is pending.
For some clients, successful completion of an available program may be an important objective. For others, the evidence or collateral consequences may make a different strategy more appropriate. The decision should follow a review of the actual case rather than a blanket assumption that a program is always the best result.
What does successful completion require?
The statute establishes the program components, but the participant must comply with the particular requirements ordered in the case. That can include the assigned education or treatment component and, when ordered, a victim-impact component. Attendance and completion documentation matter because the court ultimately determines whether the program was satisfactorily completed.
If a person is also placed in Connecticut's pretrial drug intervention and community service program for charges arising from the same arrest, § 54-56r and § 54-56q contain coordination rules. The exact obligations should be confirmed from the court's orders rather than assumed from the name of the program.
Common questions
Is IDIP only for a first OUI arrest?
The program is commonly associated with first-time impaired-driving cases, but current law also contains rules that can permit later use in limited circumstances. Eligibility must be evaluated under § 54-56r.
Does the court choose education or treatment?
The evaluation produces recommendations, and the court determines what the participant is required to complete.
Is the DMV case the same as the criminal case?
No. Connecticut DMV administrative suspension issues can proceed separately from the criminal court case.
