DWI with a CDL in North Carolina: 0.04, disqualification and your job

Three offenses that reach commercial drivers

“DUI” is the everyday word; North Carolina charges DWI. For a CDL holder there are three statutes to know, and which one applies depends on what you were driving and what was in your system.

G.S. 20-138.2 mirrors the basic DWI statute with a lower number: driving a commercial motor vehicle “While under the influence of an impairing substance,” or “After having consumed sufficient alcohol that he has, at any relevant time after the driving, an alcohol concentration of 0.04 or more,” or “With any amount of a Schedule I controlled substance, as listed in G.S. 90-89, or its metabolites in his blood or urine.” Subsection (e): “The offense in this section is a misdemeanor and any defendant convicted under this section shall be sentenced under G.S. 20-179.” You can be charged under both statutes for the same drive, but “the aggregate punishment imposed by the Court may not exceed the maximum punishment applicable to the offense involving impaired driving under G.S. 20-138.1.”

G.S. 20-138.2A has no number at all: the offense is driving a commercial motor vehicle “while consuming alcohol or while alcohol remains in the person's body.” A first offense is “a Class 3 misdemeanor...punishable by a penalty of one hundred dollars ($100.00),” and “A second or subsequent violation of this section is a misdemeanor punishable under G.S. 20-179.” Two evidence rules are built in: “The odor of an alcoholic beverage on the breath of the driver is insufficient evidence by itself” unless “the driver was offered an alcohol screening test or chemical analysis and refused,” and “the results of an alcohol screening test or the driver's refusal to submit may be used by a law enforcement officer, a court, or an administrative agency in determining if alcohol was present.” G.S. 20-138.2B applies the same standard and the same $100 penalty to a “school bus, school activity bus, child care vehicle, ambulance, other emergency medical services vehicle, firefighting vehicle, or law enforcement vehicle.”

Both DWI statutes are “offenses involving impaired driving” under G.S. 20-4.01(24a), which lists “Impaired driving in a commercial motor vehicle under G.S. 20-138.2” alongside G.S. 20-138.1. That matters for a second offense and for the seven-year lookback at sentencing. The first three charges are on the state's mandatory-appearance list, so none of them can be paid off without coming to court; a case from a Durham County arrest is heard at the Durham County Courthouse, 510 S. Dillard Street.

The CDL disqualification under G.S. 20-17.4

Disqualification is the DMV taking away the commercial privilege specifically. It is separate from the revocation of your regular license, and it does not care which vehicle you were in.

G.S. 20-17.4(a) opens: “Any of the following disqualifies a person from driving a commercial motor vehicle for one year.” The list includes “A first conviction of G.S. 20-138.1, driving while impaired,” “A first conviction of G.S. 20-138.2, driving a commercial motor vehicle while impaired,” and “Refusal to submit to a chemical test when charged with an implied-consent offense, as defined in G.S. 20-16.2.” The first item is the one that catches people: the DWI conviction in a personal car, off the clock, is a one-year trigger in its own right. A second or subsequent conviction under G.S. 20-138.2A is also a one-year trigger.

The statute's words on the longer periods: “A person is disqualified from driving a commercial motor vehicle for three years if that person is convicted of an offense or commits an act requiring disqualification under subsection (a) and the offense or act occurred while the person was transporting a hazardous material that required the motor vehicle driven to be placarded.” And under subsection (b), a person already disqualified for a conviction or refusal “who, as the result of a separate incident, is subsequently convicted of an offense or commits an act requiring disqualification under subsection (a) is disqualified for life.” G.S. 20-17.4 was amended as recently as S.L. 2024-30 and has no separate 0.04 subsection; it works by citing G.S. 20-138.2 and G.S. 20-138.2A.

Refusal deserves its own line. Refusing the chemical analysis brings the 12-month revocation of your regular license under G.S. 20-16.2(d) and, separately, the one-year commercial disqualification. The refusal page explains the DMV hearing, its $450 fee and the deadline to request it.

The 30-day civil revocation at 0.04

The rights read before the breath test say it: “Your driving privilege will be revoked immediately for at least 30 days if you refuse any test or the test result is 0.08 or more, 0.04 or more if you were driving a commercial vehicle, or 0.01 or more if you are under the age of 21.” The trigger in G.S. 20-16.5(b)(4) for commercial drivers is an alcohol concentration “of 0.04 or more at any relevant time after the driving of a commercial motor vehicle.” In Durham the magistrate at the Durham County Detention Facility, 219 S. Mangum St., enters the order at the initial appearance; you cannot drive anything for the first 10 days, and it costs $100 at the clerk's office to get the license back after 30 days (45 if surrendered late).

After day 10 a district court judge can grant a pretrial limited driving privilege, subject to the rules of G.S. 20-179.3. Do not count on it for the truck: the court's post-conviction privilege form, AOC-CR-312, states that “This limited driving privilege DOES NOT include the privilege of operating a commercial motor vehicle,” and this guide could not confirm the wording of the pretrial form. The license page covers the privilege, the DL-123 and the $100 processing fee under G.S. 20-20.2.

What it means for your work

This guide has no source on what any employer, carrier or federal agency must do when a driver is charged, and does not guess. What the North Carolina statutes say is enough to plan around.

• The disqualification follows the conviction, not the arrest. Between the arrest and the court date the question is the civil revocation and, after a refusal, the refusal revocation — both stop all driving, commercial included, at least at first.
• The post-conviction privilege form excludes commercial driving in so many words; this guide could not confirm the pretrial form's wording, so plan as if no privilege restores it.
• If the interlock applies after conviction — 0.15 or more, a prior within seven years, or Aggravated Level One — G.S. 20-17.8 restricts you to “a vehicle that is equipped with a functioning ignition interlock system,” requires you to designate “any registered vehicles owned by that person that the person operates or intends to operate,” and contains no employer-vehicle exception.
• Your regular license after a G.S. 20-138.2 conviction is revoked under G.S. 20-17(a)(2) only “if the driver's alcohol concentration level was .06 or higher”; a G.S. 20-138.1 conviction is revoked at any level. The revocation is one year for a first offense under G.S. 20-19(c1).
• Your personal auto insurance is rated under the Safe Driver Incentive Plan: driving while impaired is 12 insurance points, a 340% surcharge, and for convictions on or after July 1, 2025 the experience period is five years.
• Restoring the regular license needs the DHHS certificate of completion under G.S. 20-17.6 and a $167.25 fee under G.S. 20-7(i1). The facts this guide could source do not describe how the commercial privilege is restored when a disqualification ends; the DMV or a lawyer can say what is required.

The criminal sentence is the same 20-179 system

Whichever statute you are convicted under, G.S. 20-179 governs the sentence. The judge holds a sentencing hearing “to determine whether there are aggravating or mitigating factors that affect the sentence to be imposed,” finds any grossly aggravating factors first, and lands on one of six levels, from Level Five (a fine “up to two hundred dollars ($200.00)” and “a minimum term of not less than 24 hours and a maximum term of not more than 60 days”) to Aggravated Level One (a fine “up to ten thousand dollars ($10,000)” and “not less than 12 months and a maximum term of not more than 36 months”). An alcohol concentration of 0.15 or more is an aggravating factor. The penalties page has the full table and the factor lists; the first-offense page walks through a typical Level Five case.

Court costs come with it. The 2026 costs chart puts a breath-test DWI conviction in district court at $293 before any fine — the district court base costs plus the $100 impaired driving fee that G.S. 7A-304(a)(10) makes “payable by a defendant convicted under G.S. 20-138.1 or G.S. 20-138.2,” the pretrial release services fee and the DNA fee — and a $600 State Crime Laboratory fee if your blood was tested. Every level requires a substance abuse assessment ($100 under G.S. 122C-142.1) and the education or treatment it recommends. What a lawyer costs for a Durham DWI is on the lawyers page.
