Underage DWI in NC: What Zero Tolerance Actually Means

If you are under 21 in North Carolina, the number everyone talks about — 0.08 — does not apply to you. There is no threshold at all.

Under N.C. Gen. Stat. § 20-138.3, it is unlawful for a person under 21 to drive on a highway or public vehicular area "while consuming alcohol or at any time while he has remaining in his body any alcohol or controlled substance previously consumed."

Any alcohol. Not enough to be impaired. Not enough to fail a field test. Any amount the machine can detect. That is what "zero tolerance" actually means, and it is the single thing most families get wrong when they call.

It is a Class 2 misdemeanor — and a separate charge from DWI

Subsection (c) makes the offense a Class 2 misdemeanor. But the more important sentence in that subsection is this one: it is "not, in any circumstances, a lesser included offense of impaired driving under G.S. 20-138.1."

In plain terms: this is not a junior version of a DWI. It is its own charge, and a driver under 21 can face both out of the same traffic stop — the zero-tolerance charge for having alcohol in the body, and a full DWI if the State can prove appreciable impairment or a 0.08 reading.

There is one piece of relief built in. If someone is convicted of both offenses arising out of the same transaction, the statute says the aggregate punishment "may not exceed the maximum applicable to the offense involving impaired driving." The sentences do not stack beyond the DWI ceiling. Any minimum punishment that applies still gets imposed.

The license consequence is automatic, and it is one year

This is the part that reshapes a young person's life, and it is not up to the judge.

Under § 20-13.2(a), the DMV "must revoke" the license of anyone convicted under § 20-138.3, upon receiving the conviction record. Subsection (d) sets the length: one year.

Two additional rules in the same statute catch people off guard:

A DWI conviction under 21 triggers this revocation too. Under § 20-13.2(b), if the driver was under 21 at the time of the offense, the license "must be revoked under this section in addition to any other revocation required or authorized by law."
So does refusing the test. Under § 20-13.2(c), a willful refusal to submit to a chemical analysis while under 21 brings a revocation under this section in addition to the separate refusal revocation.

One genuine piece of good news: revocations under § 20-13.2 "run concurrently with any other revocations." They overlap rather than stacking end to end.

The hard line at 18

This is the detail almost nobody knows before they walk into court, and it is the one that decides whether a teenager keeps getting to school and work.

A limited driving privilege — a court order allowing restricted driving during a revocation — is available after a § 20-138.3 conviction, but only if the driver meets both requirements in subsection (d):

They were 18, 19, or 20 years old on the date of the offense, and
They have no prior conviction under this section.

Read that first requirement again. A 16- or 17-year-old convicted under this statute is not eligible for a limited driving privilege at all. Not a hardship exception, not a school exception. The younger driver faces the harsher practical outcome, which is the opposite of what most parents assume.

For those who do qualify, the judge may issue the privilege only if the driver otherwise meets the eligibility requirements of § 20-179.3.

Two things worth knowing before anyone pleads

The odor of alcohol, by itself, is not enough

Subsection (b1) is unusually specific, and it is worth quoting:

"The odor of an alcoholic beverage on the breath of the driver is insufficient evidence by itself to prove beyond a reasonable doubt that alcohol was remaining in the driver's body in violation of this section unless the driver was offered an alcohol screening test or chemical analysis and refused to provide all required samples."

The legislature wrote a specific evidentiary limit into this statute. An officer smelling alcohol, standing alone, does not carry the State's burden. The exception is narrow and it matters: it applies where the driver was offered a screening test or chemical analysis and refused to provide all required samples.

The screening device has rules attached to it

Subsection (b2) allows an alcohol screening test and allows the result — or a refusal — to be considered by an officer, a court, or an administrative agency. But it also says no screening test is valid "unless the device used is one approved by the Department of Health and Human Services, and the screening test is conducted in accordance with the applicable regulations of the Department as to its manner and use."

Approved device, and correct procedure. Both, or the result is not valid under the statute.

This charge is subject to implied consent

Subsection (b) makes this an alcohol-related offense subject to the implied-consent provisions of § 20-16.2. That means the whole implied-consent framework applies — the rights that must be read, the opportunity to call a witness, and the separate consequences of a refusal, which are their own revocation entirely.

Getting the license back

When the revocation period ends, restoration is not automatic paperwork. Under § 20-13.2(e), before the DMV restores the license the driver must submit proof that they have notified their insurance carrier and that they are financially responsible — typically the certificate a carrier issues for exactly this purpose.

It is worth checking the actual status of the license with the DMV rather than assuming the revocation has ended on schedule.

The practical picture

A zero-tolerance charge is a Class 2 misdemeanor with a mandatory one-year revocation, it can travel alongside a DWI rather than replacing it, and the ability to drive at all during that year turns on whether the driver had reached 18 on the date of the offense.

It is also a charge with real evidentiary requirements attached — an approved device, correct procedure, and a statute that says odor alone does not carry the State's burden. Those requirements are worth having someone examine before a young driver pleads to something that follows them for a year.
