Ignition Interlock Devices
South Carolina Ignition Interlock Device Requirements
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
The Effect of Emma's Law on DUI Offenders
On April 30, 2014, South Carolina's governor officially passed Emma's
Law, a piece of legislature which drastically impacts the lives of convicted
DUI offenders. Emma's Law was created in honor of a young girl who
was killed by a drunk driver in 2012.
Essentially, the law magnifies the punishment for all convicted drunk drivers.
Emma's Law enforces the following penalties in the state of South Carolina:
All DUI offenders: Any driver with a blood alcohol concentration (BAC) of .15 or higher must
install an IID on any vehicle they drive for six months.
First-time offenders: First-time offenders with a BAC of .08 to .14 can choose to use an IID
in order to drive with no geographic restrictions instead of a license
Repeat offenders: If a drunk driver is convicted a second or subsequent time with a BAC
of .08 and above, they must install an IID in order to drive.
These restrictions imposed by Emma's Law only increase the severity
of a DUI conviction. It is important to take action right away if you
have been arrested for driving under the influence, as the consequences
can haunt you for a lifetime. Fortunately, our firm can help.

Columbia DUI Attorney
Anyone who is convicted of a second or subsequent DUI offense in South
Carolina is required to install an IID. The driver is responsible for
paying all of the costs associated with the IID, and these include the
installation and the monthly maintenance fee; the fees are based on the
vendor's pricing schedule. In South Carolina, the approved vendors
are Smart Start, LifeSafer Interlock, and Guardian Interlock. The IID
program is considered a voluntary program; therefore, if you choose not
to enroll, then your driving privileges will remain suspended for three
years beyond your initial suspension period. To learn more about fighting
