At what blood alcohol concentration (BAC) level is a driver considered legally intoxicated in Connecticut?

In Connecticut, a driver is considered legally intoxicated when their blood alcohol concentration (BAC) reaches 0.08%. This standard applies to individuals over the age of 21 operating motor vehicles. The significance of the 0.08% BAC threshold stems from extensive research demonstrating that at this level, a driver’s ability to operate a vehicle safely is significantly impaired. This includes decreased coordination, slower reaction times, and impaired judgment—all critical skills necessary for safe driving.

The legal framework surrounding this threshold is in place to enhance road safety and discourage drinking and driving. Lower BAC limits, such as 0.05%, apply to operators of commercial vehicles and underage drivers, but the 0.08% limit is the general standard for most adult drivers.
