South Carolina DUI & DWI Laws

Drinking and driving is a serious and dangerous offense in South Carolina. You can face heavy fines, jail time, driver’s license suspensions, ignition interlock device requirements, alcohol and drug safety programs, and reinstatement fees.

If you are arrested for driving under the influence (DUI) of drugs and/or alcohol, you will face criminal penalties in court and administrative penalties with the South Carolina Department of Motor Vehicles (DMV).

On this page you’ll find information about the definitions of a DUI, the common penalties, and the steps you may need to take to reinstate your driver’s license.

South Carolina DUI Definitions

In South Carolina, it is illegal to drive a vehicle if your blood-alcohol concentration (BAC) is 0.08% or higher.

If you are younger than 21 years old, it is illegal to drive with a BAC of 0.02% or higher.

If you hold a CDL license the legal limit is 0.04% or higher.

NOTE: Depending on the circumstances of your offense, you may receive a DUI or alcohol-related violation even if your BAC is under the legal limit.

DUI or Refusing a Chemical Test Penalties in SC

The penalties for a DUI/DWI in South Carolina will vary depending on the severity of your offense and thenumber of times you’ve committed a DUI in the past 10 years. If you drink and drive you will face both criminal penalties in court and administrative penalties with the South Carolina DMV.

It is also important to remember that South Carolina has an “Implied Consent” law. This law basically states that if you drive in the state of South Carolina you agree to take a chemical test of asked to do so by a law enforcement official. Due to this law, refusing a chemical test can get you just as many, if not more, penalties from both civil and criminal court agencies.

Administrative Penalties

Administrative penalties are civil penalties and are in addition to, and separate from, criminal penalties. Once you fail or refuse a chemical test you can plan on losing your license for some period of time. You will be sent a notice for your Administrative hearing within 30 days of your hearing date. For more informations on hearing contact the Department of Motor Vehicles at (803) 896-5000.

If you decide not to contest the suspension or the hearing does not go in your favor, you will faceadministrative penalties which include a driver’s license suspension:

  • 1st offense: 6 months.
  • 1st offense: Indefinite (with a BAC 0.15% and over).
  • 2nd offense: Indefinite.
  • 3rd offense: Indefinite.

Refuse chemical test

  • 1st offense: 6 months.
  • 2nd offense: Indefinite.
  • 3rd offense: Indefinite.

For both DUI and refusing a chemical test you will be required to complete the Department of Alcohol and Other Drug Abuse Services course. Additionally you’ll have to pay a minimum $100 license reinstatement fee and carry SR22 insurance for a minimum of 3 years once your suspension is completed.

Those who have a 2nd or subsequent offense for drugs and/or alcohol, or a 1st offense involving “great bodily injury or death” will be required to have an Ignition Interlock Device (IID) installed on their vehicle if they wish to drive.

    • Maximum up to 5 years in jail.

NOTE: If you are arrested on suspicion of a DUI/DWI in South Carolina and you refuse to submit to a BAC/breathalyzer test, you will typically receive similar penalties to those above.

*A BAC of over 0.16% will cause higher fines and jail time.

South Carolina Ignition Interlock

An ignition interlock device, which attaches to your vehicle’s ignition system, is used to test your BAC before you start your vehicle.

You will be required to have an ignition interlock device if you are convicted of a 2nd or subsequent offense for a DUI/DWI. If you refuse to have an IID installed when you are required to have one in order to drive, your license will be suspended for 3 years.

All installation, maintenance and monitoring fees will be your responsibility to pay. You must keep your IID in good working order in order to be able to drive. Your IID will have to be inspected by the South Carolina Department of Probation, Pardon and Parole every 60 days.
