Connecticut DUI: What the IDIP Means for You and Why the Evaluation Matters

If you were recently arrested for DUI in Connecticut, you've probably heard the term IDIP — the Pretrial Impaired Driver Intervention Program. It used to be called the AEP, the Alcohol Education Program, and you'll still hear attorneys refer to it that way. Same program, new name. And if you qualify, it's one of the most important options available to you.

I've been doing substance abuse evaluations for Connecticut courts for years. I've also spent 24 years as a federal probation officer working directly with courts across New England. I know what the IDIP requires, what evaluators look for, and how the process actually works from the inside. Here's what you need to know.

What Is the IDIP?

The Pretrial Impaired Driver Intervention Program is a diversionary program for first-time DUI offenders in Connecticut. If you're accepted, you don't enter a guilty plea. Instead, you complete a structured program — typically 12 classes over about a year — and if you finish successfully, your DUI charge is dismissed and the records are destroyed.

That's a significant outcome. No conviction. No criminal record for this offense. That's why defense attorneys push hard to get eligible clients into the IDIP.

Who Qualifies?

The IDIP is available to first-time offenders charged with:

• DUI under C.G.S. § 14-227a (the standard adult DUI statute)
• DUI by a driver under 21 (§ 14-227g)
• DUI with a minor in the vehicle (§ 14-227m)
• DUI while operating a school bus (§ 14-227n)
• Boating while intoxicated (§ 15-133)

You are not eligible if you have a prior DUI conviction in Connecticut or any other state, if you've used the IDIP or the old AEP within the past ten years, if you hold a CDL license or permit, or if your offense caused serious injury and you can't show good cause for an exception.

That CDL exclusion matters. If you're a commercial driver, the IDIP is not available to you — and a DUI conviction will affect your CDL separately from the standard license suspension. If that's your situation, call me. There are still options, but the path is different.

The Application Process

To apply for the IDIP, you file Form JD-CR-189 with the court. There will typically be a hearing before a judge, and anyone who was injured or suffered property damage in connection with your arrest has the right to contest your application. If accepted, you pay a $250 application fee and meet with a contractor from the Department of Mental Health and Addiction Services (DMHAS), who determines what level of programming is appropriate for you.

This is where the substance abuse evaluation comes in.

The Substance Abuse Evaluation — What It Actually Is

The DMHAS contractor conducts an initial screening, but courts and attorneys often want an independent clinical evaluation as well — either to support the IDIP application, to satisfy a condition of probation, or because the court has ordered one as part of sentencing on a second or subsequent offense.

When I conduct a court-ordered substance abuse evaluation in Connecticut, here's what it involves:

A clinical interview. We talk — about the arrest, about your drinking or drug use history, about your life circumstances. I'm not trying to catch you in anything. I'm trying to get an accurate clinical picture. The clients who do best are the ones who come in and tell me the truth.

Standardized screening tools. I use validated instruments — the AUDIT, the DAST, and others depending on the situation — to assess the nature and severity of any substance use concerns.

A written report. I produce a clear, well-organized report that addresses what the court or your attorney needs. I've been writing reports for courts for 30 years. I know what judges and probation officers are looking for, and I know how to write a report that serves your interests while being clinically honest.

The evaluation typically takes about 90 minutes. Most clients are seen the same week they call.

What Happens to Your License

This is where Connecticut gets complicated, because there are two separate processes running in parallel: the criminal case and the DMV administrative suspension.

On the DMV side, if you failed or refused a chemical test, a 45-day administrative license suspension typically begins 30 days after your arrest. This is separate from any court outcome. To get your license back after the suspension, you'll need to install an Ignition Interlock Device (IID).

IID requirements after a first offense (age 21+, BAC .08 or higher): six months following restoration. For a test refusal, it's one year. Second offense: three years, with restrictions on where you can drive during the first year.

On the court side, a first conviction carries a 45-day license suspension plus one year of IID following restoration. A second conviction means a 45-day suspension plus three years of IID. A third conviction results in permanent license revocation.

If you're in the IDIP and successfully complete it, the criminal case is dismissed — which means the court-side conviction penalties don't apply. But the DMV administrative suspension from the arrest itself still stands. These are two separate tracks, and completing the IDIP doesn't erase the DMV action.

What About Second and Third Offenses?

The IDIP is only available once. If you've used it before, or if this is your second or subsequent DUI, you're looking at a criminal conviction with mandatory penalties — including the three-year IID requirement on a second offense and permanent revocation on a third.

For second and subsequent offenses, the court will almost always require a substance abuse evaluation as part of sentencing. That evaluation needs to be thorough, credible, and written by someone who understands what the court is looking for. This is where my background matters. I've sat on both sides of this process — as a federal probation officer reviewing these reports for 24 years, and now as the evaluator writing them. I know what holds up and what doesn't.
