DUI Laws in Nevada: Penalties, BAC Limits & License Suspension

In Nevada, drunk driving is charged as "Driving Under the Influence" (DUI) under Nevada Revised Statutes Chapter 484C — Nevada does not use the terms DWI, OWI, OUI, OVI, or DUII. The per se limit is 0.08% blood alcohol concentration (BAC) for regular drivers, 0.04% for commercial driver's license (CDL) holders, and 0.02% for drivers under 21 (Nevada's zero-tolerance threshold). If you were arrested, the single most urgent thing to know is this: you generally have only 7 days from the date you receive your temporary license and Notice of Revocation to request a Nevada DMV administrative hearing to fight the automatic revocation of your driving privileges. Miss that window and the revocation becomes final regardless of what happens in your criminal case. This page explains what the law says today; always confirm current numbers with the Nevada DMV or a licensed Nevada attorney before relying on them, since statutes and administrative rules change.

1. What a Nevada DUI is called and where it's defined

Nevada law refers to this offense as DUI — Driving Under the Influence of Alcohol or a Prohibited Substance, codified at NRS Chapter 484C. You may see it written informally as "drunk driving" or "DWI" in casual conversation or in national news coverage, but Nevada's statutes and court paperwork will say DUI.

2. Per se BAC limits in Nevada

• 0.08% or higher — the standard per se limit for drivers 21 and over. This 0.08% threshold is the national standard used by every state, not something unique to Nevada.
• 0.04% or higher — the limit for anyone operating a commercial motor vehicle under a CDL.
• 0.02% or higher — Nevada's "zero tolerance" limit for drivers under 21. Nevada's underage threshold is not a flat zero — it is set at 0.02%, low enough that a small amount of alcohol can trigger a violation. The 21 minimum drinking age itself is set by federal highway-funding law, not by Nevada alone.
• Nevada does not maintain a separate statutory "aggravated" or "high-BAC" DUI charge the way some states do at 0.15% or 0.16%. However, a BAC of 0.18% or higher is a recognized threshold under NRS Chapter 484C that triggers a court-ordered substance abuse evaluation and treatment as part of sentencing, and a longer ignition interlock period, even on a first offense. Confirm current treatment and testing requirements with the court, since program details can change.

Nevada also allows prosecution based on BAC measured within two hours of driving, so a test taken after you've stopped can still be used against you.

3. Implied consent and refusing a chemical test

By driving in Nevada, you've already given "implied consent" to a breath, blood, or urine test if an officer has reasonable grounds to believe you're impaired. Refusing that test is not a way to avoid consequences — it triggers its own automatic, separate penalty from the Nevada DMV:

• First refusal: automatic license revocation of 1 year, regardless of whether you're ultimately convicted of DUI in criminal court.
• Second or subsequent refusal within 7 years: automatic revocation of 3 years.
• Once you refuse, that refusal is generally treated as final — you cannot "take it back" a few minutes later and ask to test after all.
• Refusal can also be used as evidence against you at trial, and officers can seek a warrant to obtain a blood sample by force if you refuse.

Because the revocation for refusal runs independently of the criminal case, refusing does not make the situation disappear — it adds a guaranteed administrative penalty on top of whatever the DUI charge itself produces.

4. Administrative license revocation — the DMV clock is running now

Separate from any criminal prosecution, the Nevada Department of Motor Vehicles (DMV) — through its Office of Administrative Hearings — can revoke your driving privileges based purely on the arrest and test result (or refusal), before any court ever decides guilt or innocence. This is sometimes called an administrative per se or administrative revocation action.

The deadline to contest it is short: you generally have 7 days from the date you're served the Notice of Revocation (and issued a temporary driving permit) to submit a request for a DMV hearing. If that deadline passes without a request on file, the revocation proceeds automatically and you lose the right to challenge it administratively.

• Hearing requests are made to the DMV's Office of Administrative Hearings — you can call the office nearest you (Las Vegas, Reno, or Carson City) or ask the DMV about written and in-person options.
• Requesting a hearing does not by itself guarantee anything about your interim driving status — ask the DMV about your specific temporary permit and any restricted or interlock-driving options while the hearing is pending.
• Because this deadline is measured in days, not weeks, contact the Nevada DMV or a Nevada-licensed attorney immediately after arrest — do not wait to see what the criminal court does first.

5. First-offense penalties

A first Nevada DUI (with no priors within the lookback period) is charged as a misdemeanor. Based on current Nevada law:

• License revocation: a first conviction carries a license revocation period (commonly cited as 185 days, roughly six months), though many first-time offenders become eligible to drive sooner once a court-ordered ignition interlock device is installed.
• Ignition interlock device (IID): Nevada law generally requires an IID following a first conviction — confirm the current required period and any exceptions, since IID rules have been amended over time and can depend on your BAC and circumstances (a very high BAC triggers a substantially longer interlock period).
• Jail or community service: first offenses generally carry a possible jail range measured in days up to several months, or a community-service alternative measured in hours, at the court's discretion.
• Fines and fees: courts can impose fines within a statutory range, plus administrative assessments, DUI education/treatment program costs, and possible attendance at a victim impact panel.

Do not rely on any specific dollar figure or day count you read online, including here — fine and jail ranges are set in the statute but can be amended by the Nevada Legislature, and actual outcomes depend on your BAC, whether anyone was injured, and local court practice. Confirm current numbers directly with NRS Chapter 484C or a Nevada criminal defense attorney before assuming what you'll face.

6. Lookback (washout) period

Nevada uses a 7-year lookback period, measured from arrest date to arrest date, to decide whether a prior DUI counts toward enhancing a new charge (second offense, third offense, etc.). A DUI arrest older than 7 years generally will not by itself enhance a new charge to a second or third offense — but see the felony rule below, which works differently.

7. When a Nevada DUI becomes a felony

A Nevada DUI is elevated to a felony (Category B) when:

• It is your third DUI offense within the 7-year lookback period; or
• You have a prior felony DUI conviction — once you have been convicted of a felony DUI, Nevada law treats any later DUI as a felony no matter how many years have passed since the last one; or
• The DUI involves causing death or substantial bodily harm to another person — this is treated as a serious felony regardless of prior record. Confirm the exact charge and sentencing exposure with a Nevada attorney, since injury and death cases carry their own distinct statutes and penalty structures separate from ordinary repeat-offense enhancement.

Felony DUI in Nevada carries state prison time and fines well beyond misdemeanor-level exposure, and a felony DUI generally cannot be sealed from your record. If any of these factors apply to your situation, treat it as a serious felony matter and seek an attorney immediately rather than relying on general information.

What to do after a DUI arrest in Nevada

1. Note the exact date on your temporary license/Notice of Revocation paperwork. Your window to request a DMV administrative hearing starts from that date — count it immediately, don't estimate.
2. Request the DMV hearing before the deadline, even if you also plan to hire an attorney or aren't sure yet how you want to handle the criminal case. Contact the Nevada DMV Office of Administrative Hearings (Las Vegas, Reno, or Carson City office) to submit the request.
3. Ask about interim driving options — such as a restricted license tied to an ignition interlock device — so you understand whether and how you can legally drive while the administrative and criminal cases are pending.
4. Contact a Nevada-licensed criminal defense attorney as soon as possible. The DMV hearing and the criminal case are separate proceedings with separate deadlines and separate consequences (loss of license vs. criminal conviction) — an attorney can help you navigate both at once.
5. Do not drive on a revoked or suspended license while sorting this out; driving on a revoked license adds new charges on top of the DUI.
6. Gather your own timeline and paperwork — arrest time, testing time, any documents given to you at the scene or at booking — so your attorney has the full picture from day one.
7. Verify every number in this guide against the current Nevada Revised Statutes (NRS Chapter 484C), the Nevada DMV, or a Nevada attorney before making decisions, since penalties, interlock rules, and hearing procedures are updated by the Legislature and DMV regulation over time.
