What is the legal limit for driving under the influence of alcohol in Connecticut?

The legal limit under Connecticut DUI law is .08 BAC (blood alcohol content). Connecticut laws establish that to Operate While Under the Influence (OWI) with a BAC of .08 or higher is “per se” against the law. Simply driving while your blood has over .08% alcohol is illegal. The state doesn't need to prove that you were impaired or driving unsafely. The number is sufficient to find you guilty of a DUI charge. See my DUI laws & penalties page for more info.
