Connecticut law defines “under the influence” as so affected in the mental, physical, or nervous processes that the driver lacks—to an appreciable degree—the ability to function properly in relation to the operation of a vehicle.
An OUI for an elevated BAC—also called a “per se OUI,”—is based on chemical test results, and not actual level of impairment. The amount of alcohol a person can consume before exceeding the BAC limit depends on a number of factors, including gender, body size, and the type of alcohol.
