DUI Laws in South Carolina

South Carolina DUI Laws

In South Carolina, the DUI laws are as follows:

  • Illegal BAC levels
  • Implied Consent Law
  • Drugs and driving
  • Under 21 alcohol laws

Let’s look at each one. 

Illegal BAC Levels

To determine if you’re a DUI, a police officer will ask you to take a chemical test (breathalyzer, blood, or urine) to check your BAC level. 

Now, BAC stands for Blood Alcohol Concentration. In other words, they will test to see how much alcohol is in your system. 

In South Carolina, you’re a DUI if: 

  • Your BAC level is 0.08% or greater for 21 and above
  • Your BAC level is 0.04% or greater if you’re operating a commercial vehicle
  • Your BAC level is 0.02% or greater for those below 21

Say you’re above 21 years old but your BAC level is lower than 0.08%. 

Will you not be charged with DUI?

In some cases, you can still be charged — if there is evidence that you are driving impaired. This is because some people have low alcohol tolerance (meaning a person gets drunk more quickly). 

So to be safe — NEVER DRINK AND DRIVE. No matter how little you think you drank. 

Implied Consent Law

Why not just refuse a chemical test?

It’s illegal. 

According to South Carolina’s Implied Consent Law, you have already given consent to take a chemical test when asked to. You agreed to this when you got your SC driver’s license. 

Refusing to take a chemical test will result in an immediate license suspension of 6 months on your first offense, 9 months on your second, and 12 months on your third. 

Of course, if you feel the police officer had no reason to ask for a chemical test, you can file a charge against them to avoid the penalties. Just make sure to hire a DUI attorney. 

Drugs and Driving

Like alcohol, drugs can also impair your driving. 

NEWSFLASH! Even over-the-counter and prescription drugs can affect your driving — so it’s best to avoid driving when you’re taking any medication. 

Testing for drugs in your system doesn’t have an illegal level, but that doesn’t mean you can get away if you’ve just taken one pill. 

In general, a DUI can be given to you if there is enough proof that you are driving impaired — and there is any amount of drugs found in your system. 

Under 21 Alcohol Laws

Yes, the BAC level for those under 21 years old is very low. 

But that’s because these drivers are not even allowed to be drinking yet. 

In South Carolina, anyone under the age of 21 is NOT allowed to purchase, possess, or drink alcoholic beverages. 

So of course they’re also not allowed to drink and drive. 

The laws are harsher for these drivers because they are still getting the hang of driving and they can make poor decisions on the road even when semi-intoxicated. 

South Carolina DUI Penalties

Let’s move on to the penalties. 

Yes, you can expect these to be VERY harsh — to discourage drivers from drunk or drugged driving. 

Here is a table of the South Carolina DUI penalties:

You may receive even harsher penalties from the court IF:

  • You are driving under the influence and there is a minor in the vehicle
  • Your DUI resulted in property damage
  • Your DUI resulted in bodily injuries
  • Your DUI resulted in deaths

Effects of Alcohol and Impairing Drugs

Why so much stress on DUI?

Well, even just a glass of liquor or over-the-counter drugs can affect your brain. 

Here are some effects of alcohol and impairing drugs:

  • Slower reflexes
  • Poor concentration 
  • Being overconfident or feeling that you can get away with anything (leading to rash decisions)
  • Dizziness or nausea
  • Drowsiness
  • Blurred vision or double vision
  • Reduced ability to judge distance and speed
  • Difficulty to identify colors and signs

With just these effects, it’s obvious that it’s not safe for anyone to be driving when intoxicated.
