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

In South Carolina, the legal blood alcohol concentration (BAC) limit for drivers who are over 21 years old is 0.08%. This means that if a driver's BAC is 0.08% or higher, they are considered legally impaired and can be charged with driving under the influence (DUI). This standard is consistent with the national guidelines in many states, which aim to reduce the risk of accidents and ensure safer roads. Setting the BAC limit at 0.08% is based on research showing that impairment significantly increases at this level, affecting reaction times, coordination, and overall driving ability. Understanding this limit is crucial for safe driving practices and complying with the law.
