What is the legal blood alcohol concentration (BAC) limit for drivers aged 21 and over in Kentucky?

In Kentucky, the legal blood alcohol concentration (BAC) limit for drivers aged 21 and over is set at 0.08%. This standard aligns with regulations established nationally, which aim to create a uniform legal threshold for impaired driving. When a driver's BAC reaches or exceeds this limit, they are considered legally impaired, which can lead to various legal consequences, including fines, license suspension, and possible incarceration. The tie between BAC levels and impairment is supported by extensive research showing that higher alcohol levels correlate with decreased motor skills and impaired judgment, increasing the risk of accidents on the road. The other BAC limits mentioned are either lower or higher than the established legal limit, which could lead to confusion but do not represent the threshold set by law for impaired driving.
