What is the legal blood alcohol concentration (BAC) limit for drivers over 21 in North Carolina?

0.05%

0.08%

The legal blood alcohol concentration (BAC) limit for drivers over 21 in North Carolina is 0.08%. This limit is established to ensure that drivers maintain a level of impairment that does not significantly affect their ability to operate a vehicle safely. At a BAC of 0.08%, individuals are considered legally impaired, meaning their cognitive and motor functions are sufficiently affected, thereby increasing the risk of accidents.

The enforcement of this limit is an important aspect of public safety, as lower levels of alcohol can still impair individuals, but 0.08% is the established threshold for legal accountability. This level is consistent across many states in the US, reinforcing a standard for responsible drinking and driving behaviors.
