Do You Lose Your CDL If You Get a DUI in South Carolina?
If you’re a commercial driver facing DUI charges in South Carolina, you’re right to be concerned about your license.
The answer is clear: Yes, you will lose your CDL if you get a DUI in South Carolina.
Even a first offense triggers mandatory disqualification of your commercial driving privileges, regardless of whether you were in your commercial vehicle or personal car when arrested.
At Okoye Law, we understand what’s at stake for CDL holders. Your license isn’t just a credential—it’s your career and financial stability. Let’s examine exactly what happens to your commercial driving privileges after a DUI and what options you might have
CDL Holders Are Held to Higher Standards
As a commercial driver, you already know you’re held to stricter standards than regular drivers. This becomes painfully clear when facing DUI charges:
- Regular drivers face a legal BAC limit of 0.08%
- CDL holders face a much lower BAC limit of 0.04% when operating a commercial vehicle
- Even in your personal vehicle, a standard DUI will trigger CDL disqualification
The law doesn’t care if you were driving an 18-wheeler or your personal pickup truck when you got the DUI. Either way, your commercial driving privileges are in serious jeopardy.
What Happens to Your CDL After a DUI in South Carolina?
Under South Carolina law (Section 56-1-2110), a CDL holder faces the following penalties for a DUI conviction:
First DUI Offense:
- Mandatory 1-year CDL disqualification for most drivers
- Mandatory 3-year CDL disqualification if you were transporting hazardous materials
Second DUI Offense:
- Lifetime disqualification from holding a CDL
- Possible reinstatement after 10 years (but only under very limited circumstances)
What many drivers don’t realize is that these penalties apply whether you were driving your commercial vehicle or your personal car at the time of the arrest.
You Can Lose Your CDL Even Before Conviction
Here’s something that catches many CDL holders off guard: You can lose your commercial driving privileges even if you’re never convicted of DUI in criminal court.
That’s because two separate processes kick in after a DUI arrest:
- Administrative suspension through the South Carolina Department of Motor Vehicles
- Criminal prosecution through the court system
The administrative suspension happens automatically if you:
- Refuse to take a breathalyzer test
- Take the test and register above the legal limit
This suspension can start as soon as 30 days after your arrest—long before your criminal case goes to trial.
It’s Not Just About Alcohol: Other Ways to Lose Your CDL
DUI doesn’t just mean driving under the influence of alcohol. Your CDL can be disqualified for:
- Driving under the influence of illegal drugs
- Driving under the influence of certain prescription medications
- Refusing to submit to chemical testing
- Leaving the scene of an accident
- Using a vehicle to commit a felony
Each of these violations triggers the same harsh CDL penalties as an alcohol-related DUI.
Can You Get Your CDL Back After a DUI in South Carolina?
Yes, but it’s not easy.
For a first offense, you’ll need to:
- Complete your full disqualification period (1 or 3 years)
- Pay all fines and complete all court-ordered requirements
- Complete alcohol assessment and treatment if required
- Pay reinstatement fees to the South Carolina DMV
- Possibly retake CDL written and skills tests
- Provide proof of SR-22 insurance
- Install an ignition interlock device in your vehicle if ordered
Even after reinstatement, you’ll face major hurdles:
- Insurance costs will skyrocket
- Employment opportunities will be limited, as many companies won’t hire drivers with DUI records
- Future violations will trigger more severe penalties
Professional Consequences Beyond License Suspension
The fallout from a DUI goes far beyond just losing your license temporarily:
- Most employers terminate CDL drivers immediately upon DUI conviction
- Finding new employment with a DUI on your record is extremely difficult
- You may be required to disclose your DUI to potential employers for years
- A DUI remains on your driving record for 10 years in South Carolina
For many commercial drivers, a single DUI effectively ends their driving career—even after they regain their CDL eligibility.
How to Protect Your CDL After a DUI Arrest
If you’ve been arrested for DUI, you need to act fast to protect your commercial driving privileges:
- Request an administrative hearing within 30 days of your arrest to challenge the automatic license suspension
- Do not plead guilty without consulting an attorney who understands CDL regulations
- Explore alternative resolutions like reduced charges that might preserve your CDL
- Gather evidence that might help fight the charges
- Consider challenging the traffic stop, breathalyzer results, or field sobriety tests
The key is to act quickly. Once deadlines pass or a guilty plea is entered, your options for saving your CDL diminish rapidly.
