In Kentucky, what is the legal blood alcohol concentration (BAC) limit for adult drivers age 21 or older operating a motor vehicle?
The answer
Answer: D. Kentucky law explicitly establishes that an adult driver age 21 or older is legally guilty of Driving Under the Influence if their blood alcohol concentration reaches 0.08 percent or above. Furthermore, a driver can still be convicted of DUI with a BAC below 0.08 if competent evidence proves their driving was impaired.
