In South Carolina, it’s unlawful to drive with a blood alcohol content (BAC) level of 0.08% or 80 milliliters of alcohol per 100 milliliters of blood. However, if it has been proven that you are driving while impaired with alcohol, you can still get arrested even if your BAC is lower than 0.08%.
Commercial vehicle drivers are prohibited from driving with a 0.04% or higher BAC. At 0.02% BAC, drivers under the age of 21 are likewise deemed legally intoxicated. Violations of this state regulation will result in a Driving Under the Influence (DUI) charge.
One to two standard alcoholic beverages are usually sufficient to approach or exceed a BAC level of 0.08%. However, because BAC changes according to factors such as weight and gender, this quantity should only be used as a rough guide.
Before we further discuss the impaired driving laws in South Carolina, it is essential to be aware that this post aims to raise awareness about drunk driving. This site does not encourage driving under the influence in any state or region.
According to NHTSA data, there were 1,064 fatal road incidents in South Carolina in 2020. Thirty percent of this figure concerns drivers with BACs of 0.08% or above.
Driving when intoxicated should be avoided as much as possible. If you must travel after having consumed alcohol, it is much better to use a designated driver service, Uber, or a cab.
South Carolina has DUI regulations to reduce accidents caused by intoxicated driving. It is necessary to observe impaired driving legislation to prevent legal ramifications.
If you can’t avoid driving, you should check your blood alcohol level before getting behind the wheel. You can assess your blood alcohol content by using an alcohol breathalyzer.

Legal Alcohol Limit When Driving in South Carolina
Alcohol can impair judgment by reducing reflexes, hindering vision, distorting distance and speed recognition, and delaying reaction time.
These things may occur even if you don’t appear or feel inebriated. Alcohol intoxication symptoms may appear as soon as you have your first drink.
Once you drink, alcohol enters the bloodstream within 30 minutes to 2 hours. Your respiratory rate may slow down, making clear thinking more difficult.
Although the state’s legal BAC limit is 0.08%, remember that each individual reacts differently to alcohol.
The following factors may have an impact on your blood alcohol concentration:
- anxiousness and tiredness levels
- level of alcohol consumption, and
- taking prescription medicines.
Some folks may pass out after a few drinks. Even though they appear normal, their ability to drive may be predetermined. As a result, it is critical to verify your BAC before getting behind the wheel.
A BAC calculator and chart can help you figure out how much alcohol you can consume before driving. However, these strategies may not suit everyone because everyone reacts differently to alcohol. It is still better to use a certified alcohol breathalyzer to measure your BAC accurately.
