South Carolina recently rolled out a major change to how it handles DUI convictions. With the adoption of its all-offender ignition interlock law, anyone found guilty of driving under the influence—whether it’s their first offense or not—will now be required to install an ignition interlock device in their vehicle. It’s a clear sign that the state is taking a tougher approach to prevent drunk driving and promote safer roads.
This shift adds new responsibilities for those convicted and can affect everything from daily routines to long-term driving privileges. If you’ve been arrested for a DUI, getting guidance from an experienced attorney—like the team at Truslow & Truslow—can be a crucial step in understanding your next move and protecting your future.
What Is an Ignition Interlock Device?
An ignition interlock device, or IID, works as a small breathalyzer that mechanics install in cars. Drivers must blow into this device to show they haven’t consumed alcohol before their vehicle will start. The engine stays off if the device detects any alcohol.
These gadgets aim to stop drunk driving from happening again by making it almost impossible to drive while intoxicated. Technicians wire them straight into the car’s ignition system. The device might also ask for random “rolling retests” while someone drives to check they stay sober.
While often seen as a penalty, ignition interlocks work as a safety tool. They give drivers a shot at getting back some driving privileges while improving road safety for everyone.
What’s Changed Under the New Law?
Before the recent update, South Carolina only required ignition interlock devices for certain DUI convictions—typically for repeat offenders or drivers with a high blood alcohol concentration (BAC). That meant many first-time offenders could avoid having to install one.
Now, that’s no longer the case. Under the new all-offender ignition interlock law, anyone convicted of a DUI in South Carolina must install an ignition interlock device, even if it’s their first offense. This brings the state in line with many others across the country that have adopted similar “all-offender” policies aimed at reducing repeat drunk driving incidents.
The length of time the device must remain installed depends on the specifics of the offense, but even first-time offenders are now subject to this requirement. It’s a significant shift in how DUI cases are handled—and it signals a stricter, more preventative approach to DUI enforcement in the state.
Who Is Affected and How
This new law applies to anyone convicted of a DUI in South Carolina, no matter if it’s their first offense or not. That includes drivers who may have never faced legal trouble before but are now required to install and maintain an ignition interlock device.
For those affected, the impact goes beyond just installation. Offenders must cover the costs of the device, which includes installation fees, monthly maintenance, and regular reporting. They’ll also need to follow strict rules of blowing into the device before starting the car and during random retests while driving.
Tampering with the device or failing to comply with the requirements can lead to extended time on the program or additional penalties. While it may feel like a tough consequence, the goal is to ensure safer roads and help people avoid future DUI offenses.
