If under 21, you can lose your license for driving with a blood alcohol concentration of what percent or higher?

Answer: B — 0.02%

Under South Carolina law, individuals who are under the age of 21 are subject to stricter regulations regarding alcohol consumption and driving. The legal blood alcohol concentration (BAC) threshold for those under 21 is set at 0.02%. This means that if a minor is found to have a BAC of 0.02% or higher while operating a vehicle, they face penalties, including the possibility of losing their driver's license. The reasoning behind this low threshold is to discourage underage drinking and driving, as even small amounts of alcohol can significantly impair judgment and reaction times. Therefore, it reflects a strong stance towards preventing alcohol-related incidents among younger, less experienced drivers. In contrast, the legal limit of 0.08% applies to drivers who are 21 years of age and older. The lower limit for those under 21 is a preventive measure aimed at keeping young drivers safe and free from the dangers of impaired driving.
