Understanding the IID program in South Carolina

| Mar 29, 2021 | Drunk Driving |

If you are required to have an ignition interlock device (IID) installed in your vehicle after a DUI conviction, it’s imperative that you follow all the requirements established by the state. An IID may be an inconvenience – perhaps a costly and embarrassing one. However, it’s the only way that some people are able to legally drive (albeit on restricted licenses) after a DUI.

The South Carolina Department of Probation, Parole and Pardon Service (SCDPPPS) administers the IID Program and monitors those driving vehicles with IIDs. You may also see the device referred to as a Breath Alcohol Ignition Interlock Device (BAIID).

Who is required to have an IID to drive after a DUI?

An IID isn’t mandatory. However, depending on your DUI, the court could require that you successfully complete the program if you want to avoid an indefinite license suspension.

South Carolina law requires an IID to regain driving privileges for anyone with a first-time DUI whose blood alcohol content (BAC) was determined to be at least .15% and for those with a second or subsequent DUI with a BAC over the legal limit.

Violations of the IID Program

South Carolina’s laws regarding DUIs and the IID Program have been strengthened over the past decade. For example, people with an IID can face legal penalties for violations including the following:

  • Obscuring the lens of the camera
  • Tampering with the device to prevent it from operating correctly
  • Allowing anyone else to blow in to the device, either to start the vehicle or for a retest while the vehicle is running
  • Failing to bring the vehicle to an authorized service center to have the data downloaded and the device inspected at least once every 60 days.

It’s also important to understand the costs of the IID Program, since you will be responsible for paying those, in addition to any fines assessed for the DUI.

If you’re required to have an IID in order to get your license back or if you want to have one to avoid a temporary license suspension, talk with an attorney to be sure you understand what will be required of you. If you haven’t yet pled guilty or been convicted of DUI, an experienced attorney can review all of your options with you and advise you of the best strategy for dealing with the charge.
