How Do Ignition Interlock Devices Work in South Carolina?

In South Carolina, ignition interlock devices (IIDs) under the Ignition Interlock program are installed in vehicles to prevent drunk driving. An IID is essentially a breathalyzer wired into your vehicle’s ignition system.

Before starting the car, you must blow into the IID to check your blood alcohol content (BAC). If it’s over 0.02%, the vehicle won’t start. The IID also requires random retests while driving to ensure you stay sober. You must pull over and provide a breath sample.

With an IID, drinking and driving isn’t an option.

What Is the Ignition Interlock Program in South Carolina?

The Ignition Interlock Program in South Carolina requires drivers convicted of DUI to have an ignition interlock device installed before being allowed to drive again. This breathalyzer device prevents the vehicle from starting if it detects alcohol on the driver’s breath.

Offenders must blow into the handheld part of the device before starting the engine. If the blood alcohol concentration (BAC) reading is above a preset level, the vehicle will not start. This helps ensure the driver has not been drinking before getting behind the wheel. The device also requires random retests while driving to confirm the driver remains sober.

the IID program is mandatory after DUI offenses in South Carolina

To participate in the Ignition Interlock Program, you must install an approved device for a mandated period – typically 6-12 months for a first offense. The program allows DUI offenders to keep driving privileges so they can continue daily activities like going to work or school.

Penalties for Interlock Device Program Violation

If you violate the terms of South Carolina’s Ignition Interlock Device program, there are penalties.

  • The first offense is a misdemeanor. The penalty is a fine of at least $1,000 or jail for up to 1 year. The length of time you’ll have to use the IID will increase by 6 months.
  • The second offense is also a misdemeanor. The penalty is a fine of at least $5,000 or jail for up to 3 years. The time required to use the IID will increase by 1 year.
  • The third or subsequent offense is a felony. The penalty is a fine of at least $10,000 or jail for up to 10 years. You’ll have to use the IID for 3 more years.
  • Tampering with your IID or blocking the camera is a misdemeanor, punishable by a fine up to $500, jail up to 30 days, or both.
  • Allowing someone without an IID to drive your vehicle is also a misdemeanor, carrying a $500 fine, 30 days in jail, or both. The only exception is if you leased the vehicle before your DUI arrest.
  • If you ask someone else to blow into your IID or blow into an IID that isn’t assigned to you, it’s considered a misdemeanor. The penalty is a fine of up to $500, jail time of up to 30 days, or both.
