The Short Answer: Driving to Your Interlock Installation Appointment
If your license is suspended until you install an ignition interlock device, driving yourself to the installation appointment is still driving on a suspended license. South Carolina law gives you no automatic exception for that trip. The safest course is to get a ride, or to have a mobile service install the device for you.
Under the state's Ignition Interlock Device Program, you must have the device put in before you can get a restricted license. The general driving under suspension statute covers anyone who drives while a license is suspended, canceled, or revoked. It makes no exception for the trip to the installation appointment.
This article covers the problem, the legal risks, and the safer options open to you.
When South Carolina Requires an Ignition Interlock Device
South Carolina requires an ignition interlock device after certain DUI defense offenses. Two state agencies run the program together: the Department of Probation, Parole and Pardon Services (the probation department) and the Department of Motor Vehicles.
South Carolina now requires an ignition interlock device after almost every DUI conviction. Since May 2024, the Department of Motor Vehicles requires the device for anyone convicted of DUI, of driving with an unlawful alcohol concentration, of felony DUI, or of child endangerment tied to one of those offenses. That includes a first offense, whatever the blood alcohol level. A driver who is issued a temporary alcohol license while a suspension is pending must use one too. The one exception is a driver who took the breath test and registered 0.00.
Drivers who want to get back on the road sooner may also join the program by choice. That route can restore limited driving before the full suspension ends. The device still has to go in first.
How long the ignition interlock device stays on depends on the offense. Terms typically run from six months for some first offenses to several years for repeat or aggravated DUI convictions. State law sets the term for each offense, and the Department of Probation, Parole and Pardon Services can extend it under its interlock point system.
Is Your License Actually Suspended When You Go to Install the Interlock Device?
This is the heart of the question. For many drivers the answer creates a real bind.
Here is how the timeline usually works after a DUI arrest in South Carolina:
- DUI arrest and suspension. Your license is suspended through the Implied Consent process. That often happens before you ever go to court.
- Conviction and court-ordered suspension. If you are convicted, the court adds its own suspension. It may overlap with the first one or follow it.
- Program enrollment. You apply through the probation department and are approved for the Ignition Interlock Device Program.
- Install the device. You schedule the installation with a state-approved vendor.
- Restricted license issued. Once the device is in and certified, the Department of Motor Vehicles issues the ignition interlock restricted license.
The problem is clear. Your license is suspended before the IID goes in. The restricted license only becomes valid after the device is in place. You must show the Department of Motor Vehicles proof of installation. On the drive to the installation shop, you have no valid license.
This chicken-and-egg problem catches many drivers off guard. They assume that an order to install the device also lets them drive there. They do not.
Legal Risks of Driving Yourself to the Installation Appointment
Driving on a suspended license in South Carolina is a criminal offense. When the suspension comes from a DUI, the consequences can be significant.
A Driving Under Suspension charge may carry fines, jail time, or both. The exact penalty depends on the circumstances and the driver's record. Repeat offenses can bring escalating penalties, including mandatory jail time.
A new charge stacked on an open DUI case can create serious complications. Prosecutors may read a fresh driving offense as a sign that you are not taking the case seriously. That can affect plea negotiations. It can also make a favorable resolution on the DUI harder to reach.
A new charge may also extend your suspension period. The court could impose additional restrictions that delay your return to the road. The very step you took to comply with the interlock requirement could set you back by months.
Judges and prosecutors generally look favorably on drivers who follow the rules while suspended. Getting caught on the way to the shop – even with good intentions – undercuts that goodwill. The law does not accept "I was trying to comply" as a defense.
Every case is different. The consequences depend on your prior record, the jurisdiction, and other factors. Consult a DUI defense attorney about your specific circumstances before you decide anything.
Safer Alternatives for Getting Your Interlock Installed
The good news is that several practical options eliminate this risk.
Ask a friend or family member to drive you. This is the simplest solution. Anyone with a valid license can take you to the installation shop. They can wait while the device goes on your car.
Use rideshare or a taxi. Uber, Lyft, and local taxi services operate all over the Upstate and the rest of South Carolina. A ride costs far less than a new charge.
Ask for mobile installation. Many South Carolina-approved interlock vendors – among them Smart Start, LifeSafer, Intoxalock, and Draeger – will come to you. A technician comes to your home or workplace and installs the device on site. That removes the travel problem.
Coordinate the timing with your probation officer and the installer. Call your contact at the Department of Probation, Parole and Pardon Services. Then call the installation provider. Arrange an appointment time that matches the transportation you can line up.
Call the installer in advance to confirm whether mobile service is available in your area. Not every provider offers it at every location. Ask early and plan around the answer.
How the Ignition Interlock Restricted License Fits In
The ignition interlock restricted license is issued by the Department of Motor Vehicles. It lets you drive only a vehicle fitted with a certified device.
Here are the steps:
- Apply through the Department of Probation, Parole and Pardon Services for the Ignition Interlock Device Program.
- Pay the required program fees.
- Have the device installed by an approved vendor.
- Provide proof of installation to the Department of Motor Vehicles.
- Obtain the restricted license from the Department of Motor Vehicles.
The sequence matters. The restricted license is not valid before the device is in and certified. A pending application is not authorization to drive. The license covers you only after every step is done.
Drivers often ask, "Can I drive to get my interlock installed?" The answer is no. The restricted license does not cover the trip to the installation appointment. The device must be in the car before the license takes effect.
Once the restricted license is active, you may drive to work, school, court, and other approved places. You may drive only a car with the working device in it. Tampering with it, circumventing it, or failing to maintain it can lead to program violations and added penalties.
What to Do If You Have Already Been Charged With Driving Under Suspension
If you drove to the installation appointment and were stopped by police, take these steps:
Do not make statements about the trip without legal counsel. It may feel helpful to explain that you were headed to the interlock shop, but anything you say can be used against you. Speak with an attorney first.
Gather your documentation. Collect proof of your program enrollment. Get the installation appointment confirmation. Save any letters or emails from the Department of Probation, Parole and Pardon Services or the installer. That documentation may be relevant to how your case is handled.
Contact a DUI defense attorney. An attorney familiar with South Carolina's ignition interlock procedures can evaluate your situation and advise you on next steps.
Context matters in these cases. Proof that you drove to follow a court order may factor into how prosecutors and judges approach the charge. It does not create a legal defense. The statute has no exception for driving in order to comply. Good intentions alone do not override the law.
The outcome of the charge depends on your prior record, the specific facts, and the jurisdiction where the stop occurred. Every case is different, and results depend on the facts.

Frequently Asked Questions
Will My Ignition Interlock Restricted License Cover the Drive to the Installation Shop?
The restricted license is not valid until the device is installed. The Department of Motor Vehicles must receive proof of installation. The license then covers driving only in a car fitted with the device. It allows no driving at all before the device is in place, including the trip to the installation appointment.
Do South Carolina Interlock Installers Offer Mobile Installation at My Home?
Many South Carolina-approved vendors offer mobile installation. Providers like Smart Start, LifeSafer, Intoxalock, and Draeger may send a technician to your home or workplace. Availability varies by location. Call the installer before your appointment to confirm whether mobile service is an option in your area.
What Happens If I Get Pulled Over Driving to My Interlock Appointment?
You could face a Driving Under Suspension charge. Being on the way to the installation shop does not create an exception. The charge may carry fines and possible jail time. It could also complicate your existing DUI case and delay license reinstatement.
How Long After My DUI Conviction Do I Have to Install the Ignition Interlock?
The timeline depends on your sentence and on the terms set by the court and the Department of Probation, Parole and Pardon Services. It also depends on whether you want to get back on the road early through the program. Call the probation department and your attorney soon after conviction. Understanding your deadlines helps you avoid delays that extend the suspension.
Can a Family Member Drive My Car to the Installation Appointment Instead?
Yes, as long as that person holds a valid driver's license. A licensed friend or family member can drive your car to the installation shop. This is one of the safest and simplest ways to avoid a new charge. The technician will install the device on your car no matter who drove it there.
