Connecticut OUI Laws

While most states refer to drunk or impaired driving charges as "driving under the influence" (DUI) or "driving while intoxicated" (DWI), Connecticut calls it "operating under the influence" or simply "OUI." But whichever acronym you use, driving under the influence of alcohol or other drugs is a serious crime with stiff penalties. In Connecticut, for instance, all motorists are required to install an ignition interlock device (IID) after an OUI conviction before full driving privileges will be restored. After a third or subsequent OUI offense, drivers can have their license revoked permanently (subject to a hearing request after two years of revocation). Those under 21 face even tougher penalties for driving under the influence.

The following charts and links will help you better understand Connecticut's OUI laws and regulations.

Penalties for Under-21 OUI Offenders

As in other states, Connecticut has very strict penalties for minors who are convicted of driving under the influence of alcohol or other drugs. For instance, motorists under 21 whose blood alcohol concentration is measured at 0.02 or higher will have their license suspended for one year, followed by a one-year IID requirement, for the first offense. A second offense can result in a three-year suspension. 

Connecticut IID Program

You will be required to have an IID installed on your vehicle as a condition of driving (with a limited license) in Connecticut for the following offenses:

  • Failure or refusal of a BAC test
  • Operating under the influence (OUI) of alcohol or other drugs
  • Vehicular manslaughter
  • Vehicular assault
Be aware of the special penalties for failure to use the IID properly.
