Carolina Criminal Defense & DUI Lawyer UpdatesNorth Carolina treats a driver under 21 who has alcohol in the system very differently from an adult. For an adult, the question is impairment or a 0.08 reading. For anyone who has not turned 21, N.C.G.S. § 20-138.3 makes it a crime to drive on a highway or public vehicular area while consuming alcohol, or at any time while any previously consumed alcohol or controlled substance remains in the body. The State does not have to show impairment. The presence of alcohol is the offense.
People search for this as underage DUI or underage DWI, and the terms are worth sorting out before anything else. North Carolina’s formal name for the adult offense is impaired driving under N.C.G.S. § 20-138.1, and neither acronym of DUI nor DWI is referenced within statute. It does refer to driving “while under the influence of an impairing substance,” which many folks understand as “DUI.” The underage charge (N.C.G.S. § 20-138.3) is a separate offense with its own name, driving after consuming under 21, and it is not technically an impaired driving charge at all. That distinction is not academic. The two offenses are proven and punished in different ways, and the difference works in real cases.
A stop involving underage drinking and driving often starts as something small, a checkpoint, speeding, or a broken taillight, and develops with the smell of alcohol or an admission of drinking. Potential consequences involve license suspension, increased insurance premiums, and a criminal record. The frequently asked questions (and answers) below walk through how the law operates in North Carolina, what the State has to prove, and where it parts ways with an adult impaired driving charge.

| Who it reaches | |
| Drivers under 21 only. | Any driver, any age. |
| How the two relate | |
| By statute, never a lesser included offense of impaired driving. | The separate, greater charge. |
| How it is sentenced | |
| Class 2 misdemeanor on the standard misdemeanor grid. | Sentenced under § 20-179, with mandatory terms built in. |

What is the “legal limit” for drivers under 21 in North Carolina?
North Carolina sets no numeric limit for a driver under 21, because § 20-138.3 is a zero tolerance law. Any amount of alcohol, or a controlled substance not protected by the statute’s lawful-use carve-out, remaining in the body while driving can be enough to violate the law. A driver under 21 does not violate § 20-138.3 solely because a controlled substance remains in the body if it was lawfully obtained and taken in therapeutically appropriate amounts.
Underage DUI | Different From Impaired Driving
An underage DUI under § 20-138.3 and an adult impaired driving charge under § 20-138.1, the offense most people call a DWI or DUI, are separate matters that the State proves and the court punishes in different ways. Impaired driving requires proof of appreciable impairment or an alcohol concentration of 0.08 or more. The underage charge requires only that the driver was under 21 and had alcohol or a controlled substance in the body. The statute also says plainly that driving after consuming under 21 is not, in any circumstances, a lesser included offense of impaired driving, so the two stand on their own.
The sentencing structure differs as well. Impaired driving is sentenced under § 20-179, which locks in certain terms. The underage charge is an ordinary Class 2 misdemeanor sentenced on the regular misdemeanor grid, which leaves a disposition like a prayer for judgment continued on the table. That option does not exist in an impaired driving case. Whether a prayer for judgment continued helps with the license revocation or the insurance side is a separate question that turns on the facts and is worth reviewing with counsel.
What the State Has to Prove
- Prosecutor’s Burden of Proof. A DUI pursuant to § 20-138.1 requires proof of appreciable impairment or an alcohol concentration of 0.08 or more. Section 20-138.3 requires only that the driver was under 21 and had alcohol (or a controlled substance) in the body.
- Not a lesser-included offense. The statute is explicit that driving after consuming under 21 is not, in any circumstances, a lesser-included offense of DUI. The two can stand entirely on their own.
- How it is sentenced. A DUI is sentenced under the specialized structure of § 20-179, which forecloses certain dispositions. Section 20-138.3 is an ordinary Class 2 misdemeanor sentenced on the standard misdemeanor grid (§ 15A-1340.23). One practical consequence: a Prayer for Judgment Continued (PJC) can be an available disposition here, which it is not in a DWI case. (Whether a PJC helps with the DMV revocation or insurance is a separate, fact-specific question worth discussing with a lawyer.)
Underage DUI and Impaired Driving | More Than One Charge Possible
A driver under 21 can face both an underage DUI under § 20-138.3 and an impaired driving charge under § 20-138.1 out of the same stop, when the evidence also shows appreciable impairment or a 0.08 reading. The statute anticipates that pairing and limits the exposure. When a person is convicted of both offenses arising from the same transaction, the total punishment cannot exceed the ceiling that applies to the impaired driving charge, and any minimum punishment that applies to the impaired driving charge still has to be imposed. Stacking the two does not raise the ceiling, but it does pull in the impaired driving minimums.
Underage Drinking and Driving | Conviction Penalties
Section 20-138.3 is a Class 2 misdemeanor. On the North Carolina misdemeanor punishment grid, the sentencing range depends on the driver’s prior conviction level:
| Prior record | Authorized punishment | Range |
|---|---|---|
| No prior convictions (Level I) | Community | 1–30 days |
| 1–4 prior convictions (Level II) | Community or Intermediate | 1–45 days |
| 5 or more (Level III) | Community, Intermediate, or Active | 1–60 days |
For a typical young first offender, that means the authorized punishment is community punishment of 1 to 30 days, which is most often a suspended sentence with probation, court costs, and a substance-abuse assessment rather than jail. Active jail time is not an authorized disposition at Level I; it only becomes available once a driver reaches the higher prior-record levels. The statutory maximum across the board is 60 days.
What Happens to Your License After an Underage DUI Conviction?
An underage DUI conviction requires the DMV to revoke your driver license for one year under N.C.G.S. § 20-13.2. The revocation is mandatory and automatic. It flows from the conviction itself, and the sentencing judge cannot set it aside, no matter what else the judgment contains. Getting the license back later means meeting the DMV’s reinstatement conditions, which generally include proof of financial responsibility through a DL-123 from your insurer and a 0.00 alcohol restriction that remains in effect until the driver’s twenty-first birthday.
Do the Police Need a Breath Test Result to Convict?
The police do not need a breath test result to convict under § 20-138.3, but the statute sets a specific evidentiary bar that is worth understanding. By its own terms, the odor of alcohol on the driver’s breath is not enough by itself to prove beyond a reasonable doubt that alcohol remained in the body, unless the driver was offered an alcohol screening test or chemical analysis and refused to give all required samples. An officer’s testimony that they smelled alcohol, standing alone, does not carry the case. To move past that bar, the State generally needs a roadside alcohol screening test result, a chemical analysis such as the station Intoximeter or a blood test, or a refusal after a test was offered.
Can a Driver Under 21 Refuse the Breath Test?
A driver under 21 can refuse a breath test, but the consequence depends on which test is in question, and the two are frequently confused. The handheld screening device at the roadside is one thing. Declining it is not the willful refusal that carries a long revocation, though as noted above that refusal can be used as evidence that alcohol was present. The official chemical analysis is the other, the evidential Intoximeter at the station or a blood draw, governed by the implied consent law. By driving, a person consents to that testing when an officer has grounds to believe an implied consent offense occurred. Refusing the evidential test is a willful refusal, and it brings an immediate 30 day civil license revocation together with a separate one year DMV revocation for the refusal itself. That one year refusal revocation stands on its own, no matter how the criminal charge is resolved. A 30 day civil revocation can also follow a qualifying test result, not only a refusal.
Are Limited Driving Privileges Available for an Underage DUI?
A limited driving privilege may be available after an underage DUI conviction, but only under narrow conditions. The driver has to have been 18, 19, or 20 on the date of the offense and cannot have a prior conviction under this same statute. A driver who was 17 or younger does not qualify at all. When a privilege is granted, it is discretionary with the judge and restrictive in scope, generally limited to necessary purposes such as school, work, and court-ordered treatment during set hours, under the conditions in § 20-179.3.
Does an Underage DUI Affect Car Insurance?
An underage DUI conviction hits car insurance hard. Under the North Carolina Safe Driver Incentive Plan, an alcohol related conviction like this one carries heavy points, and those points translate into a large premium surcharge that lasts for years. Some carriers respond by declining to renew the policy, which can push a family into the high risk market at a much higher cost. On a shared household policy, the increase reaches well beyond the young driver.
Does an Underage DUI Stay on Your Record?
An underage DUI conviction goes on your criminal record as a Class 2 misdemeanor and shows up on background checks, and it does not fall off on its own with the passage of time. It is not treated like a speeding ticket. There is, though, a real difference between this charge and an impaired driving conviction. Because § 20-138.3 is an ordinary misdemeanor rather than an impaired driving offense, options that are closed in an impaired driving case may be open here, including a prayer for judgment continued at sentencing and, potentially, an expunction of a first conviction after the statutory waiting period. Whether any of that applies depends on the facts, the driver’s record, and the current expunction statutes, so it is a question for counsel rather than an assumption.
Can a Driver Under 21 Be Charged for Alcohol Left Over From the Night Before?
A driver under 21 can be charged under § 20-138.3 for alcohol left over from earlier drinking, the night before included, because the offense involves alcohol being in the body while driving, not on when or where it was consumed. A young driver who drank at night, slept, felt fine in the morning, and drove to class or work can still violate the statute if any alcohol remained in the system. There is no impairment requirement and no grace for the source of the alcohol.
What happens if there is an Open Container in the Car?
An open container can add a separate charge on top of the underage DUI. North Carolina’s open container law makes it unlawful to keep an open container of alcohol in the passenger area of a vehicle on a highway or public vehicular area. When officers find one during the stop, the driver can face the open container charge and, in some cases, an underage possession charge as well, which turns a single count into several that move through court together.
Underage DUI in North Carolina | Protecting the License, Record, and Next Steps
An underage DUI in North Carolina is not just a young driver’s version of an adult impaired driving charge. Driving after consuming under 21 carries its own proof rules, its own license consequences, and its own strategic questions. The State does not have to prove bad driving, slurred speech, or a 0.08 result. At the same time, the State still has to prove the charge lawfully and beyond a reasonable doubt.
That is where careful review matters. The stop, the officer’s observations, the screening test, any chemical analysis, the driver’s age, the public vehicular area issue, and the wording of the charge all deserve attention. A case that looks simple on paper can raise real questions about proof, procedure, license eligibility, and whether a disposition such as a prayer for judgment continued has practical value.
Powers Law Firm approaches underage drinking and driving charges with the same seriousness given to adult impaired driving cases, because the consequences can follow a student, a family insurance policy, and a driving record longer than the court date itself. Bill Powers has spent more than three decades in North Carolina criminal courts, regularly writes and teaches on impaired driving law, and understands how technical alcohol-related driving charges work in real courtrooms. If your son, daughter, or family member has been charged with underage DUI, driving after consuming under 21, or a related alcohol offense in the Charlotte area, Powers Law Firm may be available to review the case and explain the options.
