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.

A special operator’s license allows drivers to travel to select locations like work, school, and medical treatments.

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.

Can’t be suspended for operating while suspended.
Must have no prior alcohol-related offenses
Cannot have three or more prior moving violations on your driving history.

Intoxalock CT Interlock Devices

CT ignition interlock law requires IID installation for many OUI penalties and requires an IID for a Special Operator's Permit.

What is an Ignition Interlock Device?

An ignition interlock device CT, or IID, is a small device installed in your vehicle which:

Prevents you from starting your car if you’ve been drinking
Requires you to re-test your Breath Alcohol Content (BrAC) during trips to ensure continued sobriety

How long is a CT Interlock device required?

The court determines the length of time an interlock device must be installed, but typically it’s at least as long as the suspension period. In some cases, it may extend beyond that period.
