South Carolina State SealSouth Carolina Ignition Interlock Device Program Frequently Asked Questions

What is an Ignition Interlock Device (IID)?

An IID is a device the size of a hand held calculator that prevents a vehicle from starting if it detects a blood alcohol concentration (BAC) over a pre-set level.

How do I accumulate points ?

Each time you blow into the IID and your alcohol content is .02 or higher, you will receive a violation point.

Do I have to have an IID installed on my work vehicle?

If you or a family member own the business, you are required to have an IID installed on your work vehicle. If you or a family member do not own the business you are not required to have an IID installed on your work vehicle.

I was convicted of DUI 1st in Magistrate's Court, yet the DMV says I am required to use the IID. Why?

Placement in the IID Program is based on current and prior convictions as maintained by the DMV pursuant to Section 56-5-2941 (A)(2)(a) of the South Carolina Code.

Another person drives my vehicle sometimes. Will they have to blow into the IID to operate my vehicle?

Yes, however you are responsible for any violations associated with the device regardless of who drives the vehicle.

Is enrollment into the IID Program mandatory?

No

How much does the IID program cost?

The cost to have the device installed and monthly fees will vary among vendors.

What happens if I choose not to enroll in the IID Program?

Your license will be suspended for three (3) more years from the date the initial suspension ends.

What happens if I drive my vehicle without an IID?

This is a new offense and would result in new charges against you.

What if I own/drive multiple vehicles?

The statute requires an interlock device on all vehicles you routinely operate.

How long am I required to be in the IID program?

The length of time you are required to participate will vary depending on the number of convictions you have received. The minimum length of time in the program is two years for those having two convictions, three years for those having three convictions and lifetime for those having four or more convictions. Additionally, the time you are required to be in the program will be extended if you accumulate IID points.

What if the vehicle is not registered to me?

You must install an ignition interlock device in the vehicle that you routinely operate, regardless of who is listed on the registration.

Where do I go to have the IID Installed?

A list of certified vendors is located on the SCDPPPS website.

Will the IID turn off the vehicle while I'm driving?

No, at no point will the ignition interlock device shut off a vehicle.

Do I have to blow into the device while I am driving?

Periodically the device will indicate to the driver that they need to blow into the device. When instructed, the driver must provide a breath sample.

What happens if I have repair work done on a car with an IID?

You should inform the vendor prior to having the vehicle worked on and then present the receipt at the next calibration appointment. Note that anytime the battery is disconnected due to service work, you must bring a repair receipt to the next appointment.

Where do I go to have the IID removed?

You must go to the same vendor who installed the device to have it removed.

What is a “calibration appointment?”

Every 60 days you are required to take your vehicle into the installer and have the IID inspected and calibrated. Failure to have this calibration completed will result in one ignition interlock point.

How do I set up calibration appointments?

You are responsible for making arrangements to have the device calibrated at least every 60 days.

What happens if I sell my vehicle?

Prior to selling the vehicle you must contact the IID office for instructions. You must have another vehicle available and reinstall the device on the same date you have the device removed from the vehicle you are selling.

I received Ignition Interlock points? What happens now?

If you receive a letter from the S. C. Department of Probation, Parole and Pardon Services (SCDPPPS) indicating that you received Ignition Interlock Points (IIP's) you have the right to appeal these points to a SCDPPPS Hearing Officer. Simply send a copy of the letter sent to you by SCDPPPS, a statement regarding why you think you should not have been assessed points, and any supporting documentation to your claim to SCDPPPS – Ignition Interlock Appeal, P.O. Box 50666, Columbia, SC 29250. You have 15 days from the date of the letter to you to send in your appeal. SCDPPPS will notify you via mail regarding the outcome of your appeal.

I have accumulated IID points. Is there anyway to get rid of these points?

No, accumulated IID points do not reset during your participation in the program.

I am from out of state and want to get a SC driver’s license. How long will I have to have an IID installed on my vehicle?

According to Section 56-5-2941(c) if a person from another state becomes a resident of South Carolina while subject to an ignition interlock device requirement in another state, the person may only obtain a SC driver’s license if the person enrolls in the IIDP. The person is subject to the requirements of the IIDP for the length of time that would have been required for an offense committed in South Carolina or for the length of time that is required by the other state, whichever is longer.

When does my participation in the IID Program begin?

Driver participation in the IID Program begins when SCDMV has issued an IID restricted driver's license. Participation does not begin when the IID is installed. If the driver's license is suspended at anytime during the IID Program the time remaining on the program will be tolled.

Can I have the Ignition Interlock Device installed instead of serving the suspension time?

No. The IID requirement is in addition to any suspension period mandated by law.

Can mouthwash or foods cause a failed BAC?

If you consume or use a product that contains alcohol,you may have a failed BAC. The device does not distinguish between mouthwash or alcoholic beverages. Alcohol is alcohol.

Will doughnuts and pastries affect operation of the IID?

The sugar and yeast in pastry can prompt an IID to register a breath alcohol above the limit. Rinsing with water prior to blowing into the IID, which is always recommended, will prevent failure.

Will the IID drain the car battery?

An ignition interlock device draws less than one-quarter of an amp when not in use and less than half an amp when preparing for a test. The device won't drain the battery of a vehicle with a properly functioning electrical system unless the car isn't started for 10 days. A car with a compromised electrical system may be affected sooner, but such a vehicle would have battery problems regardless of whether an ignition interlock device was installed.
