North Carolina DWI Law and Explanation
Under the North Carolina code, a DWI is detailed in § 20‑138.1, under the heading of Impaired Driving. In order to prove that you committed a DWI, the government must prove beyond a reasonable doubt that you:
- Drove a vehicle on “any highway, any street, or any public vehicular area” within the state
- While under the influence of any impairing substance
- After having consumed sufficient alcohol that he or she has, at any relevant time after the driving, an alcohol concentration of 0.08 or more. The results of a chemical analysis shall be deemed sufficient evidence to prove a person’s alcohol concentration
- With any amount of a Schedule I controlled substance in the individual’s blood or urine.
The State must prove each element of the offense beyond a reasonable doubt.
Element 1 requires that the government prove that you actually drove a vehicle, and that it was on a public area within the state of North Carolina. If your car is parked at the time the police officer approaches your vehicle, for example, the government may not be able to prove that you were actually driving. While the judge or jury can infer that you were driving from surrounding circumstances, the burden rests on the government alone to prove that you were, in fact, driving a vehicle in a public area.
Elements 2, 3, and 4 require that the government prove impairment by alcohol or other drugs through one of several available methods, which may include field sobriety tests, chemical analysis of breath or blood, and other observations made by arresting officers. No single factor, even a BAC (blood alcohol content/concentration) result from a chemical analysis of your breath of .08 or higher, is in and of itself sufficient to support a conviction. Each factor can potentially be challenged by a skilled defense attorney, and in some cases, a DWI charge can be beaten even when the case looks bad at first glance. Every case is different, and you would be well-advised to consult a local, licensed attorney to evaluate the facts in your particular case.

Frequently Asked Questions
In North Carolina, Driving While Impaired (DWI) occurs when a person operates a motor vehicle while under the influence of alcohol, drugs, or a combination of both, impairing their physical or mental abilities. A DWI can be charged even if your blood alcohol content (BAC) is below the legal limit if impairment is observed.
North Carolina has some of the strictest DWI laws in the country. The state follows a zero-tolerance approach, meaning drivers can be arrested and charged based on observed impairment, BAC results, or refusal to submit to chemical testing under implied consent laws.
DWI penalties in North Carolina depend on the offense level, prior convictions, and aggravating factors. Penalties may include jail time, fines, probation, mandatory substance abuse treatment, community service, and license suspension.
A DWI charge begins with a traffic stop, followed by field sobriety tests and chemical testing. If law enforcement determines impairment or a BAC of 0.08% or higher, the driver may be arrested and formally charged with DWI.
North Carolina classifies DWI offenses into five sentencing levels (Level One through Level Five). Level One is the most serious misdemeanor, while Level Five is the least severe. Felony DWI may apply for repeat offenses.
The legal BAC limit in North Carolina is 0.08% for drivers age 21 and over. Commercial drivers face a 0.04% limit, and drivers under 21 are subject to a zero-tolerance standard.
After a DWI arrest, your license may be immediately suspended, and you will receive a court date. You may also face an administrative hearing regarding your driving privileges and must comply with court-ordered conditions.
North Carolina uses the term DWI (Driving While Impaired). DUI is not a separate charge under state law, although the terms are sometimes used interchangeably in casual conversation.
Under North Carolina’s implied consent law, drivers automatically agree to submit to chemical testing if lawfully arrested for DWI. Refusal can result in an automatic one-year license suspension.
Defenses may include challenging the legality of the traffic stop, accuracy of breath or blood tests, field sobriety test procedures, and violations of constitutional rights. A skilled DWI attorney can evaluate the strongest defense strategies.
A DWI conviction can result in license suspension, revocation, or restrictions. Limited driving privileges may be available in some cases, depending on prior offenses and compliance with court requirements.
Field sobriety tests assess balance, coordination, and cognitive function. Common tests include the walk-and-turn, one-leg stand, and horizontal gaze nystagmus. These tests are subjective and can be challenged in court.
Yes. Drivers under 21 are subject to stricter penalties and zero-tolerance BAC limits. Juvenile DWI cases can involve license revocation, fines, and long-term impacts on driving records.
In limited circumstances, a DWI charge may be expunged if the case is dismissed or the defendant is found not guilty. Convictions generally cannot be expunged under North Carolina law.
The total cost of a DWI conviction may include fines, court costs, attorney fees, increased insurance premiums, license restoration fees, and mandatory treatment programs, often totaling thousands of dollars.
