EmailIt is illegal in South Carolina to drive with a blood-alcohol content (BAC) of 0.08% or higher. But police officers cannot determine that by sight. They need clues to stop someone suspected of driving under the influence and science to make their case - assuming it is reliable.
What you need to know about DUI checkpoints in South Carolina
Happy hour went into overtime, but you played it cool, limiting the rounds and mixing in some appetizers to help soak up the alcohol. Sober and confident enough to get behind the wheel for the short drive home. A half-mile from your front door, police set up a checkpoint to stop traffic and question motorists about their whereabouts and destination.
Do drivers have to take field sobriety tests in South Carolina?
You're driving home after a night out with some close friends. You had a couple of drinks, but you're confident in your ability to drive safely. You're well on your way when suddenly the car in front of you slams on their brakes. You immediately brake and you quickly switch lanes to avoid a crash.
Can you receive a DUI if your BAC is below the legal limit?
In South Carolina, like in most other states, it is illegal to operate a motor vehicle if your blood alcohol concentration (BAC) is 0.08% or higher. While this limit applies to most motorists, you may wonder whether it is possible to receive DUI charges if your BAC is beneath it. In most circumstances, this outcome is unlikely to happen. Yet, if you are under age 21, or if you have a commercial driver's license (CDL), you can receive DUI charges with a BAC far lower than the legal limit.
