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

The legal blood alcohol concentration (BAC) limit for drivers under 21 in South Carolina is set at 0.00%. This means that any detectable amount of alcohol in the system of a driver under 21 is considered illegal and can result in penalties. The rationale behind this strict policy is to prevent underage drinking and promote safety on the roads, as young drivers are less experienced and may be more susceptible to the impairing effects of alcohol. Therefore, enforcing a zero-tolerance law helps to deter underage drinking and driving, aiming to reduce the risk of accidents and enhance the overall safety of all road users.
