An Ignition Interlock Device, otherwise known as an IID, is a small device that is used to prevent a vehicle from starting if it registers a blood alcohol concentration (BAC) that is over the device’s pre-set limit. The IID is installed inside the vehicle near the driver’s seat, and it is connected to the engine’s ignition system. In order to start the vehicle, the driver must blow air into the device before the vehicle can start. The driver is also required to blow into the device randomly while they are driving. If the driver’s BAC is above the pre-set level, then the vehicle will not start. If the BAC of the driver is above the pre-set level while they are driving, then some sort of an alarm will go off depending on which device was installed.
On January 1, 2008, the Prevention of Underage Drinking and Access to Alcohol Act was put into effect. The ACT implemented the IID program and designated the South Carolina Department of Probation, Parole and Pardon Services (SCDPPPS) as the agency in charge of administering the program. The SCDPPS works in collaboration with the South Carolina Department of Motor Vehicles (SCDMV) and with the South Carolina Department of Alcohol and Other Drug Abuse Services (DAODAS) to develop a program that aims at reducing drunk driving.
Under the Prevention of Underage Drinking and Access to Alcohol Act, anyone that has:
a) Been convicted of a second or subsequent DUI offense
b) Completed their license suspension period
c) Completed their Alcohol and Drug Safety Action Program (ADSAP)
And wishes to reinstate their license, is required to have an approved vendor install an IID. Once the IID has been installed, the vendor will give the driver a certificate of installation, and the driver must bring that certificate to the local SCDMV office and request an IID Driver’s License.
After the IID has been installed, the driver is required to go back to the vendor every 60 days to have the IID inspected and the data stored in the device downloaded. The vendor will transmit the data to the IIDP Administrator for review. The length of time one will be required to install an IID varies from person to person, factors that go into determining the length of time include the person’s convictions, and any possible violations the driver had during the program.
Will I be required to install an IID on my work vehicle?
The good news is no, you will not have to.
I share a vehicle with my spouse; will they have to blow into the IID?
Yes they will.
I own/use several vehicles in my household; do I have to install one on each vehicle?
You are required to install an IID on all vehicles that you drive at home.
What if my spouse is on the registration and not me?
You are still required to install an IID on all vehicles you drive for personal use, regardless of who it’s registered to.
Will the IID turn off the vehicle while I’m still driving?
No, the IID is not designed to shut off the vehicle; it only prevents it from turning on initially.
