0.05%
0.08%
0.1%
0.12%

The correct answer is: 0.08%

In North Carolina, the legal blood alcohol concentration (BAC) limit for drivers over the age of 21 is 0.08%. This standard is adopted by most states across the United States and is established to maintain road safety by reducing the risk of impaired driving. A BAC of 0.08% indicates that a person's blood contains 0.08 grams of alcohol for every 100 milliliters. Driving with a BAC at or above this limit can impair a person's ability to operate a vehicle safely, affecting coordination, reaction time, and judgment. Enforcement of this law aims to deter individuals from driving under the influence and to help reduce accidents related to alcohol consumption. The other listed BAC levels are either lower or higher than the legal limit, indicating different levels of impairment or potential legal consequences, making 0.08% the critical threshold for determining legality in North Carolina.
