Blood Alcohol Content (BAC) is a measure of alcohol in the blood as a percentage. It is calculated in grams per 100 mL of blood, so a BAC of 0.08 means your blood is 0.08% alcohol by volume.

This is the third year in a row the state transportation department has asked to lower the drunken driving threshold. Utah passed a law in 2018 to lower their drunk driving threshold to 0.05 BAC, but all other states maintain a 0.08 threshold.

While the bill has been well received by the transportation committee over the past two legislative sessions, there has yet to be a vote in either chamber of the General Assembly, said Josh Morgan, a spokesperson for Connecticut DOT. ...
