What is the minimum blood alcohol concentration (BAC) level for drivers aged 21 and over in Connecticut?

In Connecticut, the legal limit for blood alcohol concentration (BAC) for drivers aged 21 and over is set at 0.08%. This means that if a person's BAC reaches or exceeds this level while operating a vehicle, they can be charged with driving under the influence (DUI). The rationale behind this legal limit is based on research that indicates alcohol impairs a person's ability to drive safely, and 0.08% is recognized as a threshold where the risk of accidents significantly increases.

Choosing a BAC limit of 0.05%, for instance, is too low to legally define impairment, as it is often considered a safe level for most adults. Similarly, higher limits like 0.10% and 0.12% are not acceptable because they signify a greater degree of impairment and consequently a higher risk for road safety. Therefore, 0.08% is the established standard that balances safe driving practices with reasonable legal limits for adult drivers in Connecticut.
