How Do Ignition Interlock Devices Work?
If you have been convicted of a drunk driving charge, you may have to have an ignition interlock device installed on your vehicle. In South Carolina, there are several offenses for which an IID will be used. Understanding the program can help you weigh your options and build a strong defense in order to avoid losing your driving privileges.
Who Needs an IID?
According to the South Carolina Department of Probation, Parole and Pardon Services, people who will face mandatory IID program participation will be any resident of the state convicted in the state with a first DUI where the blood alcohol concentration was at 0.15 or higher. Additionally, people who are convicted of second or subsequent offenses must have the device installed. Due to the nature of South Carolina’s implied consent program, people who refuse a breath test could ask to use an IID. For example, there may be some cases in which a driver can avoid administrative restrictions by installing a device on his or her vehicle. Refusing a breath test currently comes with a six-month license suspension. Getting an IID will enable someone to continue to drive.
What Does an IID Do?
An ignition interlock device is installed on a vehicle to prevent it from turning on based on the driver’s breath alcohol concentration. The driver would blow into the device. If the machine detects a concentration at or above 0.020, the vehicle will not start. In addition to the initial breath test, the device can request subsequent testing while the vehicle is moving. Failing any of these tests will result in a violation. Depending on the severity of the failure, a driver will accumulate points. Having two points will add two months onto the length of the program the driver must complete. Having four or more points will result in a six-month driver’s license suspension and required substance abuse treatment.
If I Have an IID, Do I Retain a Full Driver’s License?
Someone who is getting an IID on his or her vehicle will have to go to the Department of Motor Vehicles to get a restricted license. That license will enable the driver to get to certain approved locations, such as work or school. Keep in mind that if you have to have one of these devices installed, you will have to pay for it. You are also responsible for any violations that accumulate if someone else drives your vehicle.
