What is the legal Blood Alcohol Concentration (BAC) limit for operating a motor vehicle in South Carolina?

The legal Blood Alcohol Concentration (BAC) limit for operating a motor vehicle in South Carolina is 0.08 percent. This means that if a driver has a BAC at or above this level, they are considered legally impaired and can be prosecuted for driving under the influence (DUI).

The other choices reflect misconceptions about BAC limits. A limit of 0.05 percent is lower than the legal limit for most adult drivers; however, it is a threshold that can affect certain drivers, such as those under 21 or commercial drivers, where stricter limits apply. A limit of 0.10 percent is above the legal threshold and would result in impairment charges for a driver. Understanding these legal limits is crucial for ensuring safety on the roads and compliance with state laws.
