Emma's Law and Ignition Interlock Device (IID) Requirements in SC

Understanding Emma's Law in South Carolina

In 2014, South Carolina dramatically shifted how it penalizes drunk driving by enacting 'Emma's Law,' named in memory of Emma Longstreet, a child killed by a repeat drunk driver. Prior to this law, most DUI offenders simply served a license suspension. Emma's Law changed the landscape by mandating the installation of an Ignition Interlock Device (IID) for certain offenders, physically preventing a car from starting if alcohol is detected on the driver's breath. Whether you are in Spartanburg, Florence, or Hilton Head, complying with the IID program is strict, expensive, and legally mandatory to keep your driving privileges.

Navigating the transition into the Ignition Interlock Device Program requires precise compliance with state agencies. Mistakes can lead to lengthy extensions of your IID requirement. We highly advise consulting a local South Carolina DUI defense attorney from our directory to help you understand your specific mandates and avoid costly compliance violations.

What is Emma's Law and Who Does it Affect?

Codified under S.C. Code Ann. § 56-5-2941 and S.C. Code Ann. § 56-5-2990, South Carolina's expanded Emma's Law operates as an all-offender ignition interlock statute. If you are convicted of a first-offense DUI or DUAC, regardless of your Blood Alcohol Concentration (BAC)-even if your BAC is below 0.15 or below 0.10-you must install an IID to restore your driving privileges, as traditional provisional licenses have been eliminated. Additionally, the law mandates IID installation for all repeat DUI offenders (second or subsequent offenses) for extended periods.

IID Installation and Maintenance Requirements

You cannot simply buy a breathalyzer online. You must use a vendor approved by the South Carolina Department of Probation, Parole and Pardon Services, Columbia (SCDPPPS), which oversees the state's IID program. You must take your vehicle to a certified installation center where the device is wired directly into your vehicle's ignition system. Furthermore, you are required to return to the service center every 30 to 60 days for a calibration check. During this check, the technician downloads the data log-which records every time you blew into the device, any failed tests, and any missed rolling retests-and transmits it to the SCDPPPS.

Dealing with IID Malfunctions and False Positives

Ignition Interlock Devices are highly sensitive pieces of technology and can occasionally register false positives from mouthwash, certain breads (like pizza dough), or spicy foods. If you fail a startup test due to a false positive, you must rinse your mouth with water and retest within a few minutes to prove you are not intoxicated. If the device malfunctions completely, you must notify your vendor immediately and contact the South Carolina Department of Probation, Parole and Pardon Services, Greenville or your local regional office. Do not attempt to fix or disconnect the device yourself, as the system will flag this as tampering.

Penalties for Tampering with the Device

South Carolina treats IID tampering as a severe violation. Modern devices are equipped with cameras that take a photograph of the person blowing into the machine. If the camera captures a friend or family member blowing into the device to start your car, or if a mechanic disconnects the battery without prior authorization from the state, you will be penalized. Tampering, circumvention, or having multiple failed breath tests (violations) will result in penalty points. Accumulating too many points will reset your time in the program, adding months or even years to your mandatory IID sentence.

How Much Does the IID Program Cost?

The financial burden of Emma's Law falls entirely on the convicted driver. You are responsible for all installation, monthly leasing, and maintenance fees paid directly to the private IID vendor.

How Long Do You Need the IID?

The length of time you must keep the IID installed depends heavily on your prior record. For any first-time DUI or DUAC offender, regardless of BAC level, the mandatory period is six months under S.C. Code Ann. § 56-5-2941. For a second DUI offense, the requirement jumps to two years. A third offense requires the IID for three years (or four years if the prior offense occurred within five years). Fourth and subsequent offenses carry lifetime requirements with potential review after five years. Keep in mind, the clock does not end automatically; your final months must be completely violation-free, or the state will extend your time in the program.
