Connecticut Requirements
In Connecticut, operating a vehicle under the influence (OUI) is a serious offense. This page will cover what you need to do to get back on the road if you’re convicted of OUI.
The CT Ignition Interlock Program
OUI incidents in Connecticut do not require a BAC to be prosecuted, and offenders will be arrested and their vehicle towed at the driver’s expense.
Anyone caught for an alcohol-related driving offense is required to install an ignition interlock device CT (IID) if their BAC is .08 or more. For drivers 21 and under, an IID is required if a BAC test shows a blood alcohol content of .02 or more. Drivers can have their driving privileges restored by applying for a Special Operator's Permit and completing all requirements if they install an IID CT.
What Happens if I Get an OUI in Connecticut?
First OUI Offense
- 45-day suspension
- IID CT must be installed for one year after restoration, or for a duration required under Administrative Per Se law, whichever is longer
Second OUI Offense
- 45-day suspension

- For the first year the IID is installed, drivers can only drive to and from work, school, treatment, ignition interlock device Connecticut service center, or probation appointments.

If you fail or refuse to complete a chemical, urine, or breath test you risk penalties as well.
- First test refusal: One year IID required
- Second test refusal: Two years IID required
- Third test refusal: Three years IID required
How Do I Get a Special Operators License if I Have an IID Requirement in Connecticut?
A special operator’s license allows drivers to travel to select locations like work, school, and medical treatments. You may be eligible for a Special Operator's permit if you qualify and complete all requirements. A special operator license holder doesn’t need to install the IID unless they have been required to do so, as the license is used for other types of offenders and circumstances.
