North Carolina’s DWI Laws and Conviction Penalties

North Carolina’s driving while intoxicated (DWI) (also called “DUI”) laws prohibit driving while under the influence of drugs or alcohol. While all states have impaired driving laws, a DWI conviction in North Carolina doesn't necessarily require a moving vehicle or even signs of physical impairment.

This article outlines what circumstances can lead to a DWI conviction and some of the possible penalties one could face if convicted of driving while intoxicated in North Carolina.

North Carolina’s DWI Laws

To convict a driver of a DWI in court, prosecutors must prove the motorist operated a motor vehicle:

• while “under the influence” of an impairing substance,
• with a blood alcohol concentration (BAC) of at least .08%, or
• with any metabolized controlled substance in their system.

(N.C. Gen. Stat. §§ 20-138.1, 20-138.2 (2025).)

In other words, a DWI conviction can be based on BAC, a failed drug test, or actual impairment.

What “Driving” Means Under North Carolina’s DWI Laws

North Carolina's laws define driving broadly. A person is considered to be driving—and can be convicted of a DWI—if in actual physical control of a moving or running vehicle. For instance, being behind the wheel with the engine running is considered actual physical control. (State v. Mabe, 355 S.E.2d 186 (N.C. App. 1987).)

Proof of Intoxication for a DWI Offense in North Carolina

As previously noted, a DWI conviction doesn’t require proof of actual impairment. A driver can be convicted of a DWI based on BAC or having drugs in their system. DWI charges based on the amount of alcohol or the presence of drugs in a driver’s system are sometimes called “per se” DWI charges.

In most cases, prosecutors will have alcohol or drug test results, making it easy to prove a per se charge. However, prosecutors also have the option of proving actual impairment. A driver is considered intoxicated if the ingested substance has caused “appreciable impairment” to the driver’s mental or physical faculties. (State v. Norton, 712 S.E.2d 387 (N.C. App. 2011).)

To prove impairment, a prosecutor will typically have the officer testify in court as to what physical signs of impairment (such as stumbling or slurred speech) the officer observed. The prosecutor might also use experts to testify as to how certain drugs can affect a person’s ability to drive.

Penalty Categories for North Carolina DWIs

In most states, the penalties for a DUI conviction are largely based on the number of prior convictions the driver has. North Carolina does things a little differently, though prior convictions are still a part of the equation.

In North Carolina, DWI offenses are categorized into levels based on the presence of certain factors. These factors are grouped into three types:

• gross aggravating factors
• aggravating factors, and
• mitigating factors.

Generally, DWI sentencing levels are based on which and how many of these factors are present in a case.

DWI Gross Aggravating Factors

DWI gross aggravating factors include:

• serious bodily injuries
• having a minor passenger
• driving while your license is revoked for a prior DWI, and
• having prior DWI convictions.

Prior DWI convictions count as gross aggravating factors only if they occurred within the past seven years. (N.C. Gen. Stat. § 20-179 (2025).)

DWI Aggravating Factors

DWI aggravating factors include:

• having a BAC of .15% or more
• causing a collision (that doesn’t involve serious bodily injuries)
• attempting to elude the police
• exceeding the speed limit by at least 30 miles per hour
• illegally passing a school bus,
• prior DWI convictions that occurred more than seven years ago, and
• reckless driving.

Having several recent traffic violations can also be counted as an aggravating factor for DWI sentencing, in certain circumstances. (N.C. Gen. Stat. § 20-179 (2025).)

DWI Mitigating Factors

DWI mitigating factors include:

• being only slightly intoxicated (a BAC of .09% or less)
• driving safely and lawfully (apart from impairment)
• having a clean driving record, and
• having a prescription for the intoxicating substance (provided that the driver took the substance as prescribed).

Also, the judge will consider it a mitigating factor where the driver voluntarily completes a mental health assessment or substance abuse treatment following a DWI arrest. Voluntarily installing and using an ignition interlock device before trial also is a mitigating factor (but not all DUI offenders may use this mitigating factor). (N.C. Gen. Stat. § 20-179 (2025).)

North Carolina’s DWI Sentencing Levels

Based on the number of aggravating factors, a DWI will be designated as level five (the least severe) to aggravated level one (the most severe). All DWI convictions require the offender to complete a substance abuse evaluation before sentencing, which the judge will consider during sentencing. (N.C. Gen. Stat. § 20-179 (2025).)

Level Five DWI Offenses

A DWI will be considered level five (the lowest level) if there are no gross aggravating factors and the mitigating factors outweigh any aggravating factors.

A level five DWI carries:

• 24 hours to 60 days in jail, and
• up to $200 in fines.

However, the jail period can generally be satisfied by community service or inpatient treatment. (N.C. Gen. Stat. § 20-179 (2025).)

Level Four DWI Offenses

A DWI will be considered level four if there are no gross aggravating factors and the aggravating and mitigating factors generally balance out.

A level four DWI carries:

• 48 hours to 120 days in jail, and
• up to $500 in fines.

Again, the jail sentence can generally be replaced with community service or inpatient treatment. (N.C. Gen. Stat. § 20-179 (2025).)

Level Three DWI Offenses

A DWI is a level three offense if it involves no gross aggravating factors and the aggravating factors substantially outweigh the mitigating factors.

A level three DWI carries:

• 72 hours to 6 months in jail, and
• up to $1,000 in fines.

The judge has the discretion to grant jail credit for community service or inpatient treatment. (N.C. Gen. Stat. § 20-179 (2025).)

Level Two DWI Offenses

Generally, a DWI that involves only one gross aggravating factor (unless it involves driving with a minor passenger) is a level two offense.

A level two DWI carries:

• 7 days to 12 months in jail, and
• up to $2,000 in fines.

The mandatory jail term can be served through 90 days of monitored sobriety. If the offender had a prior DWI within the last 5 years, they must also complete 240 hours of community service. (N.C. Gen. Stat. § 20-179 (2025).)

Level One DWI Offenses

A DWI involving the gross aggravating factor of driving with a minor passenger or two gross aggravating factors will be considered a level one offense.

A level one DWI conviction carries:

• 30 days to 24 months in jail, and
• up to $4,000 in fines.

In cases where the judge grants probation, the offender must serve at least 10 days in jail, followed by monitored sobriety. (N.C. Gen. Stat. § 20-179 (2025).)

Aggravated Level One DWI Offenses

The most serious DWI offenses are aggravated level one offenses. This classification is for DWIs involving at least three gross aggravating factors.

For an aggravated level one DWI, an offender faces:

• 12 to 36 months in jail, and
• up to $10,000 in fines.

In cases where the judge grants probation, the offender must serve at least 120 days in jail, followed by monitored sobriety. (N.C. Gen. Stat. § 20-179 (2025).)

North Carolina Felony DWI

A DWI in North Carolina can be charged as a felony if the offender has at least 3 prior DWI convictions in the past 10 years or if the current DWI results in serious injuries or deaths.

North Carolina’s DWI Habitual Violator Law

A driver who gets a fourth DWI conviction in a 10-year period can be charged with a class F felony as a "habitual violator." (N.C. Gen. Stat. § 20-138.5 (2025).)

DWIs Involving Serious Injuries or Death in North Carolina

A DWI that involved serious injury or death can be charged as a felony. "Felony serious injury by vehicle" is a class F felony. "Felony death by vehicle" is a class D felony. (N.C. Gen. Stat. § 20-141.4 (2025).)

License-Related Penalties for a North Carolina DWI Offense

A DWI will typically lead to license-related penalties. These penalties vary depending on the driver’s level of cooperation during the arrest and level of impairment. License-related penalties can result from a DWI arrest and/or conviction.

North Carolina’s Implied Consent Law

Under North Carolina’s “implied consent” law, all drivers lawfully arrested for a DWI are required to submit to a chemical test of their breath, blood, or urine. Drivers who refuse to comply with a lawful request for chemical testing will face driver’s license penalties.

When a driver refuses to take an alcohol or drug test requested by an officer, the officer will submit a report to the Division of Motor Vehicles (DMV). Generally, the DMV will revoke the driver’s license for 12 months for a refusal. If the DWI involved injury or death, this penalty will be consecutive (in addition) to any other revocation period (for a DWI conviction, for instance). Limited driving privileges (discussed below) may be available after six months of revocation. (N.C. Gen. Stat. § 20-16.2 (2025).)

License Revocation and Ignition Interlocks for DWI Convictions

All DWI convictions are reported to the DMV. The DMV will revoke the driver’s license for:

• one year for a first DWI conviction in the last seven years
• four years for a second DWI conviction in three years, and
• permanently for three or more DWI convictions, if the most recent conviction is within the last five years.

After the revocation period, all drivers are required to install an ignition interlock device (IID) on any operated vehicle. The IID must be maintained for:

• one year for a first offense
• three years for a second offense, and
• seven years for a third or subsequent offense.

In addition to the IID requirements, reinstated drivers will be subject to a lower BAC threshold for three years. (N.C. Gen. Stat. §§ 20-17, 20-17.8, 20-19 (2025).)

Early License Reinstatement

A driver who submits to alcohol monitoring can have a four-year revocation reduced to two years or a permanent revocation restored after three years. A driver also can have a license that’s subject to a permanent revocation restored after only 24 months after completing 12 successful months of monitored sobriety. (N.C. Gen. Stat. §§ 20-17.6, 20-19 (2025).)

Getting a DWI Restricted License in North Carolina

Revoked drivers are generally able to apply to the DMV for limited driving privileges. These limited licenses generally require enrollment in a treatment program and installation of an IID. The driver might also be limited to driving to certain locations and only during certain hours of the day. (N.C. Gen. Stat. § 20-179.3 (2025).)

North Carolina’s Underage Drinking and Driving Laws

North Carolina is a zero-tolerance state, meaning that drivers who are under the age of 21 are prohibited from driving with any amount of alcohol in their system.

An underage DWI offense is a class 2 misdemeanor. A conviction carries up to $1,000 in fines and a maximum of 60 days in jail. The driver’s license will also be revoked until the driver turns 21 and completes any court-ordered treatment. (N.C. Gen. Stat. §§ 15A-1340.23, 20-13.2, 20-138.3 (2025).)
