Navigating the complexities of Blood Alcohol Content (BAC) limits can be crucial for drivers in Lexington County and the broader South Carolina region. In this blog, we compare the BAC limits of Lexington County to those of South Carolina and neighboring states, providing insights into how these regulations affect drivers, and emphasize why legal guidance from Thompson and Hiller is vital if you find yourself facing DUI charges.

BAC Limits in Lexington County and South Carolina

In Lexington County, as in the rest of South Carolina, the legal BAC limit for drivers over 21 years old is 0.08%. This standard is consistent with the majority of the United States. However, for commercial drivers, the limit is more stringent at 0.04%, reflecting the higher standards expected of those who drive professionally. Furthermore, drivers under 21, the legal limit is significantly lower at 0.02%, highlighting the zero-tolerance policy for underage drinking and driving.

Penalties for Exceeding BAC Limits

Exceeding these BAC limits can lead to severe penalties, including fines, license suspension, and possible jail time. First-time offenders can face a license suspension for six months, while repeat offenders may face longer suspensions or permanent revocation.

BAC Limits in Neighboring States

To understand how Lexington County’s BAC limits measure up, it’s helpful to compare them to those of neighboring states. For instance:

  • Georgia: Similar to South Carolina, Georgia enforces a 0.08% limit for drivers over 21, and a 0.02% limit for those under 21. However, commercial drivers in Georgia also face a lower limit of 0.04%.
  • North Carolina: Adheres to the same BAC limits as South Carolina and Georgia for all driver categories.
  • Tennessee: Also maintains a BAC limit of 0.08% for the general driving population and 0.02% for drivers under 21. Commercial drivers have a limit of 0.04%.

This comparison shows that Lexington County is in alignment with the general standards of the region, promoting consistency across state lines.

Estimating BAC Levels by Drinks Consumed

Understanding how alcohol consumption affects your BAC can help you make informed decisions about drinking and driving. The following table estimates the number of drinks it might take to reach the 0.08% BAC limit, based on weight. Please note, these are estimates and individual reactions to alcohol can vary based on multiple factors including sex, medication, and overall health.

Body Weight Number of Drinks Estimated BAC
100 lbs 2-3 drinks 0.08%
140 lbs 3-4 drinks 0.08%
180 lbs 4-5 drinks 0.08%
220 lbs 5-6 drinks 0.08%

Note: One “drink” is defined as one 12 oz. beer, one 5 oz. glass of wine, or 1.5 oz. of distilled spirits, all of which typically contain the same amount of alcohol.
