Nevada DUI Statute: BAC Limits, Penalties, and License Loss

Nevada’s DUI laws make it a crime to drive, or be in actual physical control of a vehicle, while impaired by alcohol, drugs, or a combination of the two, with a per se blood alcohol limit of 0.08% for most drivers, 0.04% for commercial drivers, and 0.02% for anyone under 21. A conviction carries mandatory jail or community service, fines, license revocation, and an ignition interlock requirement on the first offense, and the penalties climb sharply with each additional offense within seven years until the third crosses into felony territory.

What Counts as a DUI

Under NRS 484C.110, it is unlawful to drive or be in actual physical control of a vehicle while impaired by alcohol, a controlled substance, or any combination.¹ The “actual physical control” language matters. You do not have to be moving. Courts have upheld convictions where the driver was asleep behind the wheel with the keys in the ignition, because the statute focuses on your ability to set the vehicle in motion.

The law also reaches prescription and over-the-counter medications. If a drug affects your ability to drive safely, a valid prescription is not a defense.

Location matters too. The statute applies “on a highway or on premises to which the public has access.”¹ Parking lots, shopping centers, and apartment complex roads open to visitors all qualify. A truly private, gated road with no public access sits outside the statute, but most places people call “private property” are not private in this legal sense.

BAC and Drug Limits

Nevada uses three BAC thresholds:

Reaching or exceeding the applicable limit is a per se violation. Prosecutors do not have to prove you were actually impaired; the number is enough.

A two-hour rule closes the delay loophole. If a test taken within two hours of driving shows a BAC at or above the legal limit, that result can be used to charge you as if the reading were taken at the wheel.¹

Prohibited Drug Levels

For drugs, Nevada sets specific concentration thresholds in NRS 484C.110(3). Meeting the level is the offense; no separate proof of impairment is required.¹

Amphetamine: 100 ng/mL blood, 500 ng/mL urine
Cocaine or cocaine metabolite: 50 ng/mL blood, 150 ng/mL urine
Heroin: 50 ng/mL blood, 2,000 ng/mL urine
Methamphetamine: 100 ng/mL blood, 500 ng/mL urine
LSD: 10 ng/mL blood, 25 ng/mL urine
PCP: 10 ng/mL blood, 25 ng/mL urine

Recreational marijuana is legal in Nevada, but the DUI thresholds are strict: 2 ng/mL of THC in blood and 5 ng/mL of the 11-OH-THC metabolite.¹ Regular users can exceed those limits days after last use, meaning a per se drug DUI charge is possible without any current impairment. The Nevada Supreme Court upheld the per se drug scheme in Williams v. State.⁴

Implied Consent and Test Refusal

By driving on Nevada roads, you give implied consent to an evidentiary chemical test of your blood, breath, urine, or other bodily substance if an officer has reasonable grounds to suspect impairment.⁵ Refusing is not free. A first refusal triggers a one-year license revocation. A second refusal within seven years of a prior test-refusal revocation runs three years.⁶ These revocations apply regardless of the outcome of any criminal case.

Roadside field sobriety tests are separate. You are not legally required to perform them, and refusing them does not carry the same automatic penalties as refusing a chemical test. Officers can still arrest based on other observations, and prosecutors can still use field sobriety results as evidence when the tests were performed.

Losing Your License Through the DMV

A DUI arrest triggers two parallel cases: an administrative one at the DMV and a criminal one in court. The administrative case moves first.

When a test shows a BAC of 0.08% or higher or a detectable prohibited substance, the officer serves an order of revocation and takes your license on the spot. You can request a temporary license valid for seven days from issuance.⁷ After that, you cannot legally drive without further action.

Under NRS 484C.210, the revocation for a positive test runs 185 days.⁶ You have a right to contest it at a DMV hearing, but you must request the hearing promptly; miss the window and the revocation stands.

After half the ineligibility period has passed, the DMV may issue a restricted license for work or necessities like food and medical care, but only on a showing of severe hardship and no available alternative transportation.⁸ Driving outside those conditions is a misdemeanor on its own.

Criminal Penalties by Offense

Criminal penalties escalate with each DUI within a seven-year window. Priors from any state count, not just Nevada.

First Offense

A first DUI is a misdemeanor. The court must impose:⁹

Two days to six months in jail or residential confinement, or 48 to 96 hours of community service as an alternative
A fine of $400 to $1,000
Attendance at an approved alcohol or substance abuse education course
An ignition interlock device for 185 days as a condition of reinstatement¹⁰

If your BAC was 0.18% or higher, the interlock requirement stretches to 12 to 36 months, and the court must order a substance abuse evaluation before sentencing.¹¹

Second Offense Within Seven Years

A second DUI stays a misdemeanor but the penalties tighten:⁹

10 days to six months in jail, with no community service substitute
A fine of $750 to $1,000
A mandatory substance abuse evaluation before sentencing
An ignition interlock device for one year¹⁰

Third Offense Within Seven Years

A third DUI is a Category B felony:⁹

One to six years in state prison, not county jail
A fine of $2,000 to $5,000
An ignition interlock device for three years¹⁰

DUI Causing Serious Injury or Death

Any DUI causing substantial bodily harm or death is a felony regardless of prior history. Under NRS 484C.430, the penalty is two to 20 years in state prison and a fine of $2,000 to $5,000.¹² The wide range gives judges room to weigh the severity of the harm.

Treatment Programs and Plea Alternatives

Nevada offers a few statutory paths that can soften or avoid the standard sentence.

First-time offenders with a BAC below 0.18% can apply under NRS 484C.320 for a treatment program. The court may suspend sentencing for up to three years while the defendant completes at least six months of treatment for an alcohol or substance use disorder. The applicant must be diagnosed by a licensed counselor or physician, pay for treatment, and either serve at least one day in jail or complete 24 hours of community service. Failure to complete the program reactivates the original sentence.

Third-time offenders facing a felony can apply under NRS 484C.340 for a court-supervised treatment program of at least three years.¹³ If granted, the court suspends further proceedings without entering a felony conviction and places the offender on probation for up to five years. Successful completion avoids the felony record; failure sends the case back for sentencing on the original charge.

Plea reductions are limited. Under NRS 484C.420, a DUI can only be dismissed or reduced when there is no probable cause or the evidence is insufficient to prove impairment beyond a reasonable doubt. Reductions typically go to reckless driving, which does not carry an automatic license revocation and can be sealed after one year rather than the seven-year wait that applies to a misdemeanor DUI.

Sealing a DUI From Your Record

A misdemeanor DUI (first or second offense) can be sealed seven years after release from custody or completion of a suspended sentence, whichever is later. A felony third-offense DUI generally cannot be sealed at all.¹⁴ The narrow exception covers offenders who completed the statewide sobriety and drug monitoring program and had the conviction entered at the second-offense level.

Costs Beyond the Fine

The statutory fine is only part of what a Nevada DUI actually costs. A first offense commonly runs around $10,000 or more once every consequence is added up. Expect to pay for:

Court costs and assessments on top of the base fine⁹
Tuition for the mandatory DUI education program
Installation, monthly monitoring, and calibration fees for the ignition interlock device
SR-22 high-risk insurance filing for three years after revocation, which raises premiums
DMV license reinstatement fees
Defense attorney fees, commonly $2,500 to $10,000 for a first offense

None of these expenses are tax-deductible. The IRS classifies DUI fines, court costs, and personal legal expenses as nondeductible.¹⁵

Where Nevada Law Does Not Reach

Two situations often catch drivers by surprise because state law is not the only law that applies.

A DUI on National Park Service land in Nevada is charged under 36 CFR 4.23 rather than NRS 484C.¹⁶ The federal regulation uses the same 0.08% threshold but classifies the offense as a Class B misdemeanor carrying up to six months in jail and a $5,000 fine, decided by a federal magistrate without a jury. Test refusal on federal land is separately prohibited and admissible against you. On military bases and other federal enclaves, the Assimilative Crimes Act can pull in Nevada’s state penalties when no specific federal regulation covers the conduct.

Immigration and cross-border travel bring their own risks. A single DUI does not automatically make a noncitizen deportable or inadmissible, but two or more convictions can put someone at risk of removal and can block visa renewal, adjustment of status, or naturalization. Canada treats DUI as a serious criminal offense and can deny entry at the border based on a U.S. conviction; applicants can seek a Temporary Resident Permit (roughly three to six months to process, valid up to three years) or pursue criminal rehabilitation once at least five years have passed since completing sentencing. Pilots with FAA medical certificates must report any alcohol-related conviction or administrative action within 60 days, and a second offense, or a first with a BAC of 0.15% or higher, triggers a mandatory Substance Abuse Professional evaluation. Commercial driver’s license holders face federal disqualification rules on top of Nevada’s penalties, and holders of state professional licenses may face separate disciplinary proceedings from their licensing board.
