In Nevada, the standard DUI BAC limit is 0.08% under NRS 484C.110. A first DUI offense carries 2 days to 6 months in jail, a $400–$1,000 fine, mandatory DUI school, and a 90-day license suspension under NRS 484C.400. Refusing a breathalyzer triggers an automatic 1-year license revocation under Nevada's implied consent law (NRS 484C.160). A third DUI or DUI causing injury or death becomes a felony under NRS 484C.430. If arrested for DUI in Las Vegas, do not answer questions beyond providing identification — call a DUI attorney immediately.
Why Nevada DUI Law Is a YMYL-Level Serious Matter
A DUI conviction in Nevada is not a minor traffic matter. It can result in mandatory jail time, thousands of dollars in fines and fees, a suspended driver's license, mandatory alcohol treatment programs, and a permanent criminal record that follows you across state lines. For commercial drivers or those with professional licenses, a DUI conviction can end a career.
Because the consequences are so severe, this guide holds itself to YMYL (Your Money or Your Life) editorial standards: every legal claim is cited to a specific Nevada Revised Statute. This is general information only — not legal advice. If you have been arrested for DUI in Las Vegas, Henderson, or anywhere in Clark County, the single most important step is to call a licensed Nevada DUI attorney before you say anything further to law enforcement.
Nevada BAC Limits — NRS 484C.110
Under NRS 484C.110, it is unlawful in Nevada to operate a vehicle with a blood alcohol concentration (BAC) at or above the following levels:
| Driver Type | BAC Limit | Authority |
|---|---|---|
| Standard drivers (age 21+) | 0.08% | NRS 484C.110(1)(a) |
| Commercial vehicle drivers | 0.04% | NRS 484C.110(1)(b) |
| Drivers under age 21 | 0.02% | NRS 484C.110(1)(c) |
Important: You can be charged with DUI in Nevada even if your BAC is below these limits. If a law enforcement officer observes signs of impairment — slurred speech, difficulty with field sobriety tests, smell of alcohol — you may be arrested and charged regardless of your measured BAC. Nevada law prohibits driving while under the influence of alcohol or any controlled substance to a degree that renders you incapable of safely driving.
NRS 484C.110 — Per Se DUI Threshold
A person shall not drive or be in actual physical control of a vehicle on a highway or on premises to which the public has access with a concentration of alcohol of 0.08 or more in their blood or breath, measured within 2 hours after driving. BAC at or above this threshold is a per se violation — meaning impairment does not need to be separately proven by the prosecution.
First Offense DUI Penalties — NRS 484C.400
Under NRS 484C.400, a first-offense DUI with no aggravating factors is classified as a misdemeanor in Nevada. The mandatory minimum and maximum penalties are:
- Jail: Mandatory minimum 2 days (48 hours) up to 6 months. The court may allow community service in lieu of some jail time.
- Fine: $400 minimum to $1,000 maximum, plus substantial court costs and fees that typically bring the total to $1,500–$3,000.
- DUI School: Mandatory attendance at a Nevada-approved DUI education program.
- License Suspension: 90-day suspension of Nevada driving privileges through the Department of Motor Vehicles.
- Victim Impact Panel: Mandatory attendance at a victim impact panel.
If your BAC was 0.18% or higher at the time of testing, you are subject to additional mandatory penalties including extended DUI school and possible treatment assessment. High-BAC cases are treated more harshly even on a first offense.
Second Offense DUI Within 7 Years — NRS 484C.400
A second DUI offense within 7 years of the first conviction is still a misdemeanor in Nevada but carries significantly higher mandatory penalties under NRS 484C.400:
- Jail: Mandatory minimum 10 days up to 6 months (home confinement may be available for part of the sentence).
- Fine: $750 minimum to $1,000 maximum, plus elevated court costs.
- Ignition Interlock Device: Mandatory installation of an ignition interlock device (IID) on all vehicles you own or operate for 1 to 3 years.
- License Revocation: 1-year driver's license revocation through the Nevada DMV.
- Residential Confinement or Treatment: The court may order residential confinement or participation in an alcohol treatment program.
The 7-year lookback period means that if your first DUI was more than 7 years ago, a new DUI is treated as a first offense for penalty purposes — though it may still be considered in sentencing discretion.
Felony DUI in Nevada — NRS 484C.430
Under NRS 484C.430, a DUI is charged as a Category B felony in Nevada under any of the following circumstances:
- Third offense: A third DUI conviction within 7 years of the second conviction.
- DUI causing substantial bodily harm: A DUI that results in substantial bodily injury to another person.
- DUI causing death: A DUI that results in the death of another person (vehicular manslaughter or DUI causing death).
Felony DUI penalties under NRS 484C.430 include:
- 1 to 6 years in Nevada State Prison for a third-offense felony DUI.
- 2 to 20 years in Nevada State Prison for DUI causing substantial bodily harm or death, depending on circumstances.
- Substantial fines from $2,000 to $5,000.
- Permanent revocation of driving privileges (with no possibility of reinstatement for 3 years on some felony DUI convictions).
A felony DUI conviction also affects civil rights — including the right to possess firearms — and is very difficult to seal under Nevada record law. If you are facing felony DUI charges, retaining an experienced Nevada criminal defense attorney immediately is essential.
NRS 484C.430 — Felony DUI Threshold
If a person violates NRS 484C.110 and causes the death of or substantial bodily harm to another person, or if the offense is a third or subsequent offense within 7 years, the person is guilty of a Category B felony. Penalties include 1–6 years imprisonment for a third offense, and 2–20 years for DUI causing death or substantial bodily harm.
Implied Consent Law — NRS 484C.160
Nevada's implied consent law, codified at NRS 484C.160, states that any person who drives a vehicle on Nevada highways is deemed to have given consent to a chemical test of their blood, breath, or urine to determine BAC or the presence of controlled substances.
Refusing to submit to a breathalyzer or blood test when lawfully requested by a law enforcement officer carries severe automatic consequences:
- First refusal: Automatic 1-year revocation of your Nevada driver's license by the DMV — separate from any criminal DUI case.
- Second refusal within 7 years: 3-year driver's license revocation.
- Evidence at trial: Your refusal can be admitted as evidence against you in the criminal case. Prosecutors frequently argue that refusal indicates consciousness of guilt.
The license revocation from a refusal happens through the Nevada DMV's administrative process — not the criminal court — and begins automatically unless you request an administrative hearing within 7 days of the arrest. Missing this deadline waives your right to contest the revocation administratively.
What to Do After a DUI Arrest in Las Vegas
If you are arrested for DUI in Las Vegas or anywhere in Clark County, the decisions you make in the hours following arrest have a direct impact on the outcome of your case. Follow these steps:
- Provide identification only. You are legally required to provide your name, driver's license, vehicle registration, and proof of insurance. Beyond that, do not answer questions about where you were, how much you drank, or where you are going. Politely state: "I am invoking my right to remain silent and would like to speak with an attorney."
- Do not resist arrest. Any physical resistance will add criminal charges and complicate your defense.
- Call a DUI attorney immediately. Do not wait until the next morning. An attorney can advise you on the chemical test decision, the administrative license hearing deadline (7 days), and preservation of evidence.
- Request an administrative DMV hearing within 7 days. After a DUI arrest in Nevada, you have 7 days to request an administrative hearing with the Nevada DMV to contest any license suspension or revocation. Missing this deadline means your license is automatically suspended.
- Document everything. As soon as you are released, write down everything you remember about the stop, the officer's conduct, field sobriety tests, and the testing process. Memory fades quickly.
Do Not Discuss Your Case on Social Media
Anything you post on social media after a DUI arrest — including check-ins, photos, or comments — can be used as evidence against you. Prosecutors regularly monitor social media accounts of defendants. Do not discuss your case, the arrest, or your alcohol consumption online under any circumstances.
Why a Local Las Vegas DUI Attorney Matters
DUI defense in Clark County is highly local. Different courts handle cases differently, and attorney familiarity with local prosecutors, judges, and procedures is a real advantage. The two most common courts handling Las Vegas DUI misdemeanors are the Las Vegas Justice Court (for offenses occurring within the City of Las Vegas) and the Henderson Justice Court (for offenses in Henderson). These courts have different prosecutors, different administrative processes, and different norms around plea negotiations.
An attorney who regularly practices in the specific court where your case is filed will know the tendencies of the prosecutors assigned to DUI cases, the available diversion programs (if any), and the judges' sentencing patterns. This local knowledge is often the difference between a negotiated outcome and going to trial without leverage.

Frequently Asked Questions — Nevada DUI Laws
Under NRS 484C.110, the legal blood alcohol concentration (BAC) limit in Nevada is 0.08% for standard drivers age 21 and over. Commercial drivers are subject to a stricter 0.04% limit. Drivers under age 21 face a zero-tolerance limit of 0.02% BAC. You can also be charged with DUI if you are impaired regardless of your BAC level — impairment can be established by officer observation and field sobriety test performance even without a chemical test.
Under Nevada's implied consent law (NRS 484C.160), driving on Nevada roads constitutes implied consent to chemical testing. Refusing a breathalyzer or blood test results in an automatic 1-year driver's license revocation for a first refusal — separate from any criminal DUI penalties. This revocation begins automatically through the Nevada DMV unless you request an administrative hearing within 7 days of arrest. A refusal can also be used as evidence against you at trial. Speak with a Nevada DUI attorney before deciding whether to consent to chemical testing.
A misdemeanor DUI conviction in Nevada stays on your driving record for 7 years and is used to determine whether a subsequent DUI is charged as a second or third offense under NRS 484C.400. For record sealing purposes under NRS 179.245, a misdemeanor DUI conviction is not eligible for sealing until 7 years after the case closes. Felony DUI convictions cannot be sealed. Your criminal record (separate from your DMV record) is visible to employers, landlords, and licensing boards during background checks unless and until it is legally sealed.
