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

    Answer: 0.08%

    South Carolina, like all US states, sets the per se DUI BAC limit at 0.08% for non-commercial drivers aged 21 and older.

  2. What is the legal BAC limit for drivers under 21 in South Carolina?

    Answer: 0.02%

    South Carolina enforces a 0.02% BAC limit for drivers under 21, effectively a near-zero tolerance policy for underage drinking and driving.

  3. What does SC's 'implied consent' law mean?

    Answer: By driving in SC, you consent to chemical tests if lawfully arrested for DUI

    Implied consent means that operating a vehicle in SC constitutes automatic agreement to submit to breath, blood, or urine testing if arrested for DUI.

  4. What happens to your license if you refuse a breath test in South Carolina?

    Answer: Automatic suspension for 6 months for a first refusal

    Under SC's implied consent law, refusing a breath test results in an automatic 6-month license suspension for a first offense.

  5. Alcohol affects driving ability primarily by:

    Answer: Reducing judgment, reaction time, and coordination

    Even small amounts of alcohol impair judgment, slow reaction time, and reduce coordination, all critical driving skills.

  6. Which of the following is the only effective way to sober up after drinking?

    Answer: Time

    Only time allows the body to metabolize alcohol; coffee, cold showers, and exercise do not speed up the process or reduce impairment.
