In Connecticut, the legal blood alcohol concentration (BAC) limit for drivers over 21 is set at 0.08%. This limit is established based on research that indicates this level significantly impairs driving ability, increasing the risk of accidents. If a driver's BAC is at or above this threshold, they are considered to be under the influence, which can result in legal penalties, including fines, license suspension, and potential imprisonment.

The 0.08% limit aligns with standards observed in many other states, promoting consistency in DUI laws across the nation. It's important for drivers to understand that even below this limit, alcohol can still impair judgment and reaction times, and it is always safest to avoid drinking and driving altogether. The establishment of this specific BAC limit helps law enforcement to have a clear standard for enforcement and helps to raise awareness about the risks associated with drinking and driving.
