A Brief Guide to the Ignition Interlock Device Program in South Carolina


Any DUI typically comes with stiff consequences no matter where you live. If you’re a driver living in South Carolina, you should be aware of the Ignition Interlock Device (IID) Program and what may happen to someone convicted of driving under the influence. Make sure you understand the details the IID—and how you can avoid violating the program.

BAIID Basics

An IID, also referred to as a Breath Alcohol Ignition Interlock Device (BAIID) by the South Carolina Department of Probation, Parole and Pardon Services, is a device that you must install in your car following a DUI conviction that meets certain requirements.

If you want to continue driving after a DUI, you will need to have the BAIID installed if:

  1. It is your first DUI and you had a Blood Alcohol Concentration of 0.15% or higher.
  2. It is your second or subsequent DUI offense.

The department will let you know by mail if you can take part in the program, at which point you will be responsible for getting the BAIID installed and picking up your “II” restricted license.

You have the option to decide against the IID Program, but if you do, your license will stay suspended for a period of three years or longer (depending on the date of your offense).


Completing the BAIID Program

If you decide to do the program, you will be required to complete it from start to finish. You’ll have to pay to have the BAIID to be installed in any vehicle you drive and connected to the car’s ignition system. You will have to blow into the device before the car will start, and again at certain times while you are driving.

With the device installed, you will have to keep your breath alcohol concentration (BrAC) under 0.02%. If it meets or exceeds that level before you start driving, your car will not start. If you go above 0.02% while driving, the device will record a violation of the program (and no, don’t worry—your car won’t automatically shut off while you’re driving).


About IID Program Violations

Besides keeping your BrAC under the required minimum, you have a few other responsibilities under the IID Program. When you break the program rules, you will be given points. The more points you accumulate, of course, the stricter your penalty will be.

Examples of other IID Program Rules:

  • You must report to a service center provider every 60 days to have your BAIID calibrated.
  • You may not change with the device or try to remove it yourself.
  • You may not let another person blow into the device for you.

The results of violating the IID Program may include having to be in the program longer, a requirement to attend a substance abuse treatment program, or a driver’s license suspension. You have the option to appeal your points, with a different process depending on how many points you have collected.


Important Notes about the BAIID

Keep in mind that certain foods or products, like mouthwash, contain alcohol and may affect the results of your breath test. Try to stay away from any alcohol-based products before you drive. If you have more than one car, you will need to have a BAIID on everyone you want to keep driving—even if you share it with another person.
Remember that a South Carolina DUI can come with a range of other penalties, from jail time to community service to alcohol rehabilitation. It’s important to work with a competent DUI attorney to ensure you are treated fairly throughout the legal process.  Call The Woods Law Firm to
