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

In Georgia, the legal limit for blood alcohol concentration (BAC) for drivers aged 21 and over is 0.08%. This standard is in line with federal guidelines and is based on extensive research into the effects of alcohol on driving abilities.

When a driver's BAC reaches this level, they are considered impaired in a way that significantly increases the risk of accidents and injuries on the road. At 0.08%, cognitive functions such as judgment, coordination, and reaction time become adversely affected, making it much more difficult to drive safely.

Setting the legal limit at this percentage helps law enforcement and legal authorities establish a clear and enforceable standard for impaired driving. The values above or below this limit reflect varying degrees of impairment, where lower levels may also affect a driver’s ability but have not been legally defined as grounds for DUI in the same way.

By adhering to the 0.08% threshold, Georgia prioritizes road safety and reinforces the message that driving under the influence of alcohol can have serious legal consequences and endanger lives.
