Driving Under the Influence Laws in North Carolina

Driving Under the Influence in North Carolina

Driving under the influence in North Carolina is charged as impaired driving, often called DWI, and the legal line is an alcohol concentration of 0.08 or any amount of an impairing substance that affects your driving. A DWI is a criminal charge, but when an impaired driver hurts or kills someone, it also becomes the foundation of a civil injury claim and, in the worst cases, a felony.

This page covers both sides: what the impaired driving law says, what the penalties are, and what it means for you if a drunk or drugged driver caused your crash. If you were the one hurt, the driver's impairment can be a powerful part of your case.

What Is the Legal Limit for DWI in North Carolina?

A 0.08 alcohol concentration, or impairment from any substance. The impaired driving statute, G.S. 20-138.1(a), defines the offense:

A person commits the offense of impaired driving if he drives any vehicle upon any highway, any street, or any public vehicular area within this State: (1) While under the influence of an impairing substance; or (2) After having consumed sufficient alcohol that he has, at any relevant time after the driving, an alcohol concentration of 0.08 or more ... or (3) With any amount of a Schedule I controlled substance ... or its metabolites in his blood or urine.

Note the first prong: you can be convicted while under 0.08 if an impairing substance affected your driving. The number is not the only way to prove the case.

What Are the Lower Limits for Commercial Drivers and Drivers Under 21?

Stricter ones. A commercial driver is impaired at 0.04, half the standard limit. A driver under 21 is held to a zero-tolerance rule, meaning any alcohol in their system can support a charge. Those lower thresholds reflect the higher risk these drivers carry.

What Are the Penalties for DWI in North Carolina?

They run through six sentencing levels. After a conviction, the judge weighs grossly aggravating, aggravating, and mitigating factors and sentences under G.S. 20-179, from most to least serious: Aggravated Level One, Level One, Level Two, Level Three, Level Four, and Level Five. Aggravated Level One can carry up to 36 months in prison and a fine of up to $10,000, while a Level Five is the lightest. A DWI conviction also triggers a license revocation.

What Counts as a Grossly Aggravating Factor in a North Carolina DWI?

The facts that push a sentence to the top. Grossly aggravating factors include a prior DWI within seven years, driving while already revoked for impaired driving, causing serious injury to another person, and having a child under 18 in the vehicle. The presence of these factors determines whether a case is moved to Level One or Aggravated Level One.

What Happens if an Impaired Driver Causes a Death or Serious Injury?

The charges become felonies. Under G.S. 20-141.4, an impaired driver who unintentionally causes a death commits felony death by vehicle, a Class D felony, and one who causes serious injury commits felony serious injury by vehicle, a Class F felony. A prior impaired-driving conviction within seven years raises these to aggravated felonies with even harsher sentencing.

Can I Sue a Drunk Driver Who Hurt Me in North Carolina?

Yes, and the impairment strengthens the case. Beyond the criminal charge, you can bring a personal injury claim for your medical bills, lost wages, pain and suffering, and other losses. The driver's impairment is strong evidence of negligence and can also support a claim for punitive damages, which are intended to punish especially reckless conduct. Our North Carolina car accident lawyers build these cases around evidence of impairment.

Does the Criminal Case Decide My Injury Claim?

No, they are separate. The criminal case is the State punishing the driver; your civil claim is you recovering for your losses. They run on different tracks with different standards of proof, and you do not have to wait for the criminal case to finish to pursue your claim. A criminal conviction can help your civil case, but your claim does not depend on one.

Can I Recover Punitive Damages From a Drunk Driver in North Carolina?

Sometimes. North Carolina allows punitive damages when a defendant's conduct was especially egregious, and driving while impaired is the classic example. Punitive damages are over and above your medical bills and lost wages, and they are meant to punish and deter. Whether they apply depends on the facts, which is why the evidence of impairment matters so much.

What if the Impaired Driver Was Underinsured or Had No Insurance?

Your own coverage can fill the gap. Impaired drivers are often carrying minimum coverage or none at all. Uninsured and underinsured motorist coverage on your North Carolina policy can step in to pay when the at-fault driver cannot. Preserving those rights early is important, especially in a serious injury case.

What Should I Do if a Drunk Driver Hit Me in North Carolina?

Document the signs of impairment and get help. Call 911 so officers can investigate impairment at the scene, note anything you observed about the driver, get witness names, photograph everything, and get medical care the same day. The police DWI investigation can serve as valuable evidence in your civil claim. Our page on what to do after a collision covers the steps.

How Long Do I Have to File a Claim After a DWI Crash?

Generally, a few years from the crash, often three, with a shorter window for wrongful death. The criminal case timeline is separate and does not control your civil deadline. Acting early protects the evidence while the investigation is fresh.

What if the Drunk Driver Who Hit Me Was Working at the Time?

There may be a second source of recovery. When an impaired driver was on the job, running a delivery, driving a company vehicle, or working a route, the employer can sometimes be held responsible for the harm their employee caused on the clock. That matters because a business often carries far more insurance than an individual. Identifying an employment connection early can significantly affect the overall value of a case.

Can a Bar or Host Be Liable for Over-Serving the Driver in North Carolina?

In limited circumstances, yes. North Carolina recognizes narrow claims against those who serve alcohol to someone who then causes harm, such as serving a visibly intoxicated person or providing alcohol to someone underage who then drives and injures another. These claims are fact-specific and have real limits, but where they apply, they open another avenue of responsibility beyond the driver. Our North Carolina car accident lawyers can evaluate whether one fits your facts.

Does It Matter That the Driver Has Not Been Convicted Yet?

No. You do not have to wait for the criminal case to resolve to pursue your civil claim, and a not-yet-convicted driver can still be held civilly responsible. The two cases move on separate tracks. Waiting on the criminal process can cost you valuable time while evidence fades, so the civil investigation should start early.

Does It Help My Claim if the Driver Was Charged With Felony Death or Serious Injury by Vehicle?

It can, because it documents the impairment and the harm. A felony charge under the death-by-vehicle or serious-injury-by-vehicle statute reflects that the State believes an impaired driver caused the death or serious injury, and the investigation behind it produces evidence your civil claim can use. Your claim remains separate and does not depend on a conviction, but the criminal case can be a valuable source of evidence. The earlier the civil side gets involved, the more of that evidence can be preserved.
