DUI and Your CDL in Georgia

Why a DUI Is Different for CDL Holders

For a commercial driver, a DUI arrest threatens more than a driver’s license. It can end a career. Federal rules adopted by Georgia (49 C.F.R. § 383.51 and O.C.G.A. § 40-5-151) disqualify commercial drivers from operating a commercial motor vehicle (CMV) for certain offenses. Those rules apply whether you were driving your truck or your own car at the time of the arrest.

The 0.04 Limit in a Commercial Vehicle

While driving a commercial motor vehicle, the per se limit is 0.04, half the 0.08 limit for ordinary drivers. The implied consent notice read to commercial drivers warns that a result of 0.04 or more, or a refusal, will lead to disqualification from operating a CMV for at least one year. In a personal vehicle, the usual 0.08 limit applies, but a conviction still counts against your CDL.

CDL Disqualification Periods

• First DUI conviction, first 0.04 violation in a CMV, or first refusal: one-year disqualification, in either a commercial or personal vehicle.
• First offense while hauling placarded hazardous materials: three-year disqualification.
• Second qualifying offense, even years later: lifetime disqualification. Federal rules allow some drivers to seek reinstatement after 10 years by completing an approved rehabilitation program, but a later offense makes the disqualification permanent.

There is no hardship permit for commercial driving. Georgia law specifically bars DDS from issuing a limited permit that would allow you to operate a CMV during a disqualification. The ignition interlock permit is also off the table for anyone who currently holds a CDL. You would have to downgrade to a regular license, which means giving up commercial driving for the life of the permit.

No “Masking” of CDL Convictions

Federal law prohibits states from masking, deferring, or diverting traffic convictions for CDL holders. That means programs that might keep an ordinary driver’s record clean often cannot be used to protect a CDL, even for an offense in your personal car. For a commercial driver, the realistic goal is usually a dismissal, an acquittal, or a reduction to a charge that does not trigger disqualification. That outcome has to be built from the evidence.

The ALS Hearing Is Critical for Commercial Drivers

A CDL holder who refuses testing, or who tests over the limit, faces an administrative license suspension and can face a CDL disqualification before the criminal case is ever decided. Because the interlock permit is not available to CDL holders, requesting the hearing within 30 days is usually the only way to fight the administrative action. It also gives your lawyer a chance to cross-examine the officer under oath, and that testimony can be used later in a motions hearing. See the first 30 days after a DUI arrest for the timeline.

How We Defend CDL DUI Cases

We treat every CDL case as though the career depends on it, because it often does. We look at:

• The basis for the stop, including commercial vehicle inspection stops;
• Whether the correct commercial-driver implied consent notice was read, and when (see refusal and implied consent);
• How the breath test or blood test was collected and analyzed, especially close to the 0.04 threshold;
• Whether field sobriety tests were given on appropriate ground and scored correctly; and
• Whether drug evidence supports a DUI-drugs charge at all.

If you drive for a living, call before your first court date and before the 30-day ALS deadline. Your employer may also have its own reporting rules, so ask us about those when we talk.
