Nevada DUI Laws: What the Law Says in Plain Language

An over-the-shoulder view of a driver inside a car at night in Las Vegas, with a police car’s flashing lights visible through the windshield.

Under Nevada DUI laws, you can be charged if you drive or are in actual physical control of a vehicle while impaired by alcohol or drugs, or with a blood or breath alcohol level of 0.08 or more (0.04 for commercial drivers). Penalties grow with each offense in a 7-year window, and a third offense or a DUI that injures someone is a felony.

This guide walks through what the statute actually says. If you have already been stopped or arrested, our post on your rights after a Las Vegas DUI arrest covers what to do next. The main DUI statutes live in Chapter 484C of the Nevada Revised Statutes, and we cite the specific sections below.

What Counts as a DUI in Nevada?

Nevada has two main ways to prove a DUI. The first is impairment: being “under the influence” of alcohol, a controlled substance, or a combination of the two, no matter what a test shows. The second is a number: a blood or breath alcohol concentration of 0.08 or more (NRS 484C.110).

A few details in the statute surprise people:

  • The 2-hour rule. It is also unlawful to have a 0.08 or higher reading on a test taken within 2 hours after driving. The law gives a narrow defense if you can show you drank after you stopped driving and before the test.
  • Actual physical control. You do not have to be moving. Sitting in the driver’s seat of a running car can be enough, depending on the facts.
  • More than public roads. The law covers highways and “premises to which the public has access,” which includes places like casino parking garages and shopping center lots.

 

Here are the alcohol limits that apply to different drivers:

Driver Alcohol Limit Source
Drivers 21 and older 0.08 NRS 484C.110
Commercial vehicle drivers 0.04 NRS 484C.120
Drivers under 21 0.02 Nevada DMV

If you hold a commercial license, the lower limit applies while you drive a commercial vehicle, and a DUI in any vehicle can affect your CDL. Our page on CDL DUI defense in Las Vegas explains how that plays out.

Can You Get a DUI for Marijuana or Prescription Medication in Nevada?

Yes. Nevada law makes it unlawful to drive while under the influence of a controlled substance, and the statute states plainly that having a legal right to use the drug is not a defense (NRS 484C.110). That means a valid prescription does not protect you if the medication impaired your driving.

Nevada also sets “per se” limits for certain drugs measured in blood or urine. For marijuana, the blood limits are 2 nanograms per milliliter of THC and 5 nanograms per milliliter of its active metabolite, though under current law those marijuana limits apply only in felony-level cases, such as a third offense or a DUI causing injury or death. In other marijuana cases, prosecutors have to show actual impairment. The statute lists separate limits for drugs such as cocaine, methamphetamine, and heroin.

Drug DUI cases often turn on lab timing, how the blood was drawn and stored, and whether the officer’s observations match real impairment. Our page on prescription drug DUI charges goes into those issues in more detail.

What Is Nevada's Implied Consent Law?

By driving in Nevada, you are considered to have agreed to a breath, blood, or urine test if an officer has reasonable grounds to believe you drove impaired (NRS 484C.160). This is called implied consent.

You can still say no, but refusal has its own consequences. According to the Nevada DMV, refusing a test leads to a license revocation of at least one year, which is longer than the minimum revocation for a first DUI. The officer can also apply for a warrant and, with one, use reasonable force to draw blood.

This is why roadside decisions matter. A refusal does not end the investigation, and it can create a separate license problem even if the criminal case is later reduced or dismissed. Officers at Las Vegas DUI checkpoints follow the same implied consent rules as officers on a regular traffic stop.

How Are First, Second, and Third DUI Offenses Different?

Nevada counts prior DUIs within 7 years of the new offense (NRS 484C.400). Time spent in prison, on probation, or on parole for a prior DUI does not count toward those 7 years, so the window can stretch longer than it looks. A DUI from another state counts too.

Offense (Within 7 Years) Classification Jail or Prison Other Requirements
First Misdemeanor 2 days to 6 months in jail or residential confinement, or 48 to 96 hours of community service Fine, DUI education course, victim impact panel
Second Misdemeanor 20 days to 6 months in jail or residential confinement Fine, treatment program, victim impact panel
Third Category B felony 1 to 6 years in state prison Fine, evaluation, possible treatment

Two rules raise the stakes further. Once you have a felony DUI on your record, any later DUI is a felony with 2 to 15 years in prison, no matter how much time has passed (NRS 484C.410). And Nevada law limits plea bargaining: a prosecutor cannot dismiss a DUI charge in exchange for a plea to a lesser offense unless the charge lacks probable cause or cannot be proved (NRS 484C.420).

What Happens to Your Driver's License After a Nevada DUI?

A DUI arrest starts two separate cases: the criminal case in court and an administrative case with the DMV. The DMV can revoke your license based on a failed or refused test, even if the court case is later reduced or dismissed.

Based on the Nevada DMV’s published guidelines, the minimum revocation periods are:

  1. First DUI: 185 days
  2. Second DUI within 7 years: 1 year
  3. Third DUI within 7 years, or a DUI causing death or serious injury: 3 years
  4. Refusing a chemical test: at least 1 year

Nevada also requires an ignition interlock device after a conviction: 185 days for a first offense, 1 year for a second, and 3 years for a felony DUI (NRS 484C.460). Drivers can often get back on the road sooner by installing an interlock and getting a restricted license. Reinstatement also requires SR-22 proof of insurance for 3 years.

You can challenge a revocation through the DMV Office of Administrative Hearings, but the deadline to ask is short, and reinstating early with an interlock can end your right to that hearing. Make that choice with your attorney before you act.

When Is a DUI With Injury a Felony
in Nevada?

A DUI becomes a category B felony when the impaired driver’s act or neglect causes another person’s death or substantial bodily harm (NRS 484C.430). Under Nevada law, substantial bodily harm means a serious injury, such as one that creates a substantial risk of death or causes lasting disfigurement or loss of function.

The prison ranges under the statute are:

  • Substantial bodily harm: 2 to 20 years
  • Death, no prior DUI: 2 to 25 years
  • Death, with one or two prior DUIs: 5 to 25 years

Probation is not available for this charge, and the sentence cannot be suspended. If a child under 15 was in the vehicle, the court must treat that as an aggravating factor. A driver with three or more prior DUIs who causes a death can be charged with vehicular homicide under a separate section (NRS 484C.130).

Because these cases often involve accident reconstruction, medical records, and blood test timing, the defense work starts early. Our DUI with injury defense page explains how we approach them.

Frequently Asked Questions About Nevada DUI Laws

Can I get a DUI while parked in Nevada?

You can. The statute covers anyone in “actual physical control” of a vehicle, not only someone who is driving. Courts look at the full picture, such as where you were sitting, whether the engine was running, where the keys were, and where the car was parked. Sleeping in the back seat with the engine off is treated very differently from sitting behind the wheel with the motor on.

Yes. Nevada counts a conviction from another state as a prior offense if that state’s law prohibits the same or similar conduct. A DUI from California or Arizona within the 7-year window can turn a Nevada first offense into a second offense.

According to the Nevada DMV, DUI convictions and license revocations stay on your full DMV record for life. The DMV notes they are generally reported to insurance companies and most employers for 3 years and to other state DMVs for 10 years. Criminal court records are kept indefinitely.

It depends on the evidence. Nevada law bars prosecutors from dropping a DUI charge just to accept a plea to something lesser. A reduction is possible when the charge lacks probable cause or the state cannot prove it, which is why a close review of the stop, the testing, and the lab work matters.
