DUI vs DWI in NC What’s the Difference?
If you’ve heard people use DUI, DWI, OWI, or OUI interchangeably, you’re not alone. Across the U.S., these acronyms describe impaired-driving offenses—but their meaning depends on where you live.
In North Carolina, there’s no legal distinction between “DUI” and “DWI.” The state’s Safe Roads Act of 1983 merged all drunk- and drugged-driving offenses into a single crime: Driving While Impaired (DWI).
What Do DWI, DUI, OWI, and OUI Mean?
- DUI – Driving Under the Influence
- DWI – Driving While Impaired (or Driving While Intoxicated in some states)
- OWI – Operating While Impaired
- OUI – Operating Under the Influence
- OVI/OMVI – Operating a (Motor) Vehicle Impaired
Different names, same concept: operating a vehicle while your ability to drive is impaired by alcohol, drugs, or another substance. In North Carolina, a DWI conviction can stem from alcohol, illegal drugs, or even prescription medication.
I cannot say enough good things about my attorney. His knowledge of DWI case law is vast and his professionalism in court was unmatched. He was able to get my entire case dismissed before trial by showing that the officer who charged me did not follow proper arrest procedure. The judge called his motion to dismiss “brilliant”. I highly recommend him for any DWI-related matter.
Mike represented me on two DWI charges both were dismissed. DWI charges are hard to overcome if convicted you will lose your license, pay high fees, do community service, and your insurance will really be high. If you want to have a fighting chance call Mike he is very knowledgeable and helpful.
Mr. Dummit was a great help to me in an interlock case. He was very honest about the process and what to expect in different cases. He was very re-assuring when all the facts about my case were gathered and consulted with me numerous times before the actual case. He was always very prepared, was available at times that many attorneys would not be, and treated me with the utmost respect in all situations. His staff was very friendly and professional in all their dealings with me and I would recommend his law firm overwhelmingly to anyone that is in need. I can not express my appreciation enough to Mr. Dummit, Mr. Fradin and their whole firm.
North Carolina Doesn’t Distinguish Between DUI and DWI
Before 1983, North Carolina law treated a DUI as a lesser offense than a DWI. That changed with the Safe Roads Act. Today, whether you call it DUI, DWI, OWI, or OUI, it’s prosecuted under one statute: DWI.
It also means you can’t plead down to a separate “DUI” to avoid the penalties that come with a DWI conviction. Learn more about North Carolina DWI sentencing levels.
Aiding and Abetting a DWI
If you knowingly hand your keys to someone who is impaired, you can be charged with aiding and abetting a DWI. It’s punished at Level 5—the lowest sentencing level—but still carries fines, license consequences, and a criminal record.
“Per Se” Violations and Schedule I Drugs
North Carolina is a zero-tolerance state for Schedule I controlled substances. If you have any amount of a Schedule I drug in your system—such as heroin, morphine, MDA, or certain hallucinogens—you can be convicted of DWI without the state proving actual impairment. This is similar to the 0.08 BAC per se standard for alcohol: the presence alone may trigger a conviction. Evidence often comes from chemical testing, such as blood tests, in DWI cases.
Penalties for DWI in North Carolina
A DWI conviction brings immediate and lasting consequences. Depending on the facts and sentencing level, penalties may include:
- Fines and court costs
- License suspension or revocation
- Jail time
- Community service requirements
- Mandatory alcohol or substance-abuse assessment
- Significantly higher car insurance premiums
These do not include out-of-pocket expenses like towing, bond, or hiring an attorney. Even a Level 5 conviction can disrupt your job, finances, and ability to drive. Explore potential DWI defense strategies.
