DUI

Updated August 15, 2026

Being stopped at a DUI checkpoint or on the roadside in Nevada can be stressful, whether it happens on the Strip or on a quiet residential street. Knowing what officers can and cannot do, and understanding your own rights, can make a real difference in how the stop unfolds and in how a case is later defended. To pull a driver over, an officer generally needs reasonable suspicion that a traffic law was violated or that the driver is impaired; an arrest requires the higher standard of probable cause. This guide walks through what typically happens during a roadside DUI stop in Nevada, what the law actually requires of you, and where the process goes from there.

The Role of Law Enforcement in a DUI Stop

When an officer pulls over a driver suspected of impaired driving, the officer will usually ask questions meant to gather information, such as where you are coming from and whether you have been drinking or taking any medications. As a driver, you are required to provide your driver’s license, vehicle registration, and proof of insurance. Beyond that, you are not obligated to answer questions that could incriminate you, and you have the right to remain silent.

Staying calm and cooperative while limiting what you say is usually the safest approach. Consulting an experienced DUI defense attorney as early as possible, even before charges are filed, can help you avoid statements or missteps that end up working against you later in the case.

DUI Checkpoints and What to Expect

DUI checkpoints, sometimes called administrative roadblocks, are legal in Nevada under NRS 484B.570. To be valid, a checkpoint must be clearly visible to approaching traffic from at least 100 yards away, marked with proper signage, and operated in a neutral, non-discriminatory manner, such as stopping every fifth or tenth vehicle rather than singling out specific drivers. Deliberately driving through a checkpoint without stopping is a separate gross misdemeanor under NRS 484B.580.

At a checkpoint, officers can ask for your license, registration, and proof of insurance, and may ask whether you have been drinking. A vehicle search still requires probable cause, a valid warrant, or your consent; being stopped at a checkpoint alone does not authorize a search.

If an officer develops suspicion of impairment, you may be asked to perform field sobriety tests or a preliminary breath test. Field sobriety tests are voluntary in Nevada, meaning you can decline them without an automatic penalty, although the officer may still arrest you based on other observations. A separate rule applies once you are arrested: under Nevada’s implied consent law, refusing the evidentiary breath or blood test that follows an arrest triggers an automatic license revocation and can be used as evidence against you in court.

The DUI Stop Process

When you are stopped at the roadside, an officer typically follows a similar sequence of steps to evaluate whether you are driving under the influence:

• Initial interaction: The officer approaches and asks for your license, registration, and proof of insurance. Hand these over calmly, without sudden movements or arguing.
• Field sobriety tests: If the officer suspects impairment, you may be asked to walk in a straight line, stand on one leg, or follow an object with your eyes. These are voluntary; the officer is watching for balance, coordination, and the ability to follow instructions.
• Breath testing: If the officer continues to suspect impairment, a preliminary breath test may be requested at the scene. A reading at or above Nevada’s legal limit, combined with other signs of impairment, can lead to an arrest.
• Arrest and further testing: If arrested, you will be taken in for an evidentiary breath or blood test to establish your blood alcohol concentration (BAC) for the criminal case. Depending on the result and the circumstances, the charge can range from a misdemeanor to a felony.

Nevada’s BAC Limit and How It’s Measured

Nevada’s legal blood alcohol concentration limit for drivers 21 and older is 0.08%. That said, a driver with a lower BAC can still be arrested and charged if the officer believes their ability to drive safely was impaired. Field sobriety tests follow the standardized procedures published by the National Highway Traffic Safety Administration, and deviations from that standardized administration can sometimes be raised in a driver’s defense; our related article on challenging a field sobriety test goes into more detail.

Common DUI Penalties in Nevada

Penalties depend heavily on whether it is a first offense and whether aggravating factors are present. For a first-offense DUI within seven years, Nevada law sets out the following under NRS 484C.400:

• Fines: $400 to $1,000, plus court costs and administrative fees.
• Jail or community service: Two days to six months in jail, though courts often allow this to be satisfied instead through 48 to 96 hours of community service.
• License revocation: A 185-day license revocation, with the possibility of driving sooner through the ignition interlock reinstatement process described below.
• DUI school: Completion of a DUI education program, and a substance abuse evaluation if your BAC was 0.18% or higher.
• Ignition interlock device: Since a 2018 change in Nevada law, an ignition interlock device is required for every DUI conviction, regardless of BAC, as a condition of reinstating driving privileges.
• Victim impact panel: Attendance at a panel where people affected by impaired driving share their experiences.

Separately, refusing an evidentiary breath or blood test after arrest carries its own one-year license revocation, which increases to three years for a repeat refusal within seven years. Penalties escalate significantly for second and third offenses, and for cases involving a minor in the vehicle, an accident causing injury, or a BAC well above the legal limit. You can review how these consequences interact with your driving record in our article on how long a DUI stays on your record in Nevada, and the Nevada DMV’s own DUI reinstatement guidance outlines the current interlock and SR-22 requirements in detail.

Understanding the Legal Process After an Arrest

Once you are arrested, the case moves through both a criminal track and a separate DMV administrative process:

• Initial hearing: You are brought before a judge, informed of the charges, and asked to enter a plea. Having a DUI attorney present is important at this stage.
• Building a defense: Your attorney reviews the stop, the testing procedures, and whether the officer had reasonable suspicion to stop you and probable cause to arrest you, looking for procedural errors that could weaken the prosecution’s case.
• Trial or negotiation: Depending on the strength of the evidence, your attorney may pursue a trial or negotiate for reduced charges or penalties.

Separately, you generally have only seven days after your arrest to request a DMV administrative hearing to contest the license revocation itself; missing that window can mean losing your license even if the criminal case is later resolved in your favor. You can check the status of your license at any point through our guide on how to check if your license is suspended in Nevada.

What a DUI Lawyer Can Do for You

Because a DUI arrest triggers both a criminal case and a DMV license matter, working with an experienced Las Vegas DUI defense attorney early on can make a meaningful difference in both. At Lipp Law LLC, that typically includes reviewing whether the stop and arrest were properly conducted, challenging the accuracy of breath or field sobriety test results, and negotiating with the prosecution toward the most favorable outcome available given the facts of your case.

Frequently Asked Questions About DUI in Nevada

What should I do if I’m pulled over for a suspected DUI in Nevada?
Stay calm, provide your license, registration, and proof of insurance, and avoid answering questions that could be self-incriminating. You have the right to speak with an attorney before answering further questions.

Can I refuse a field sobriety test or a breathalyzer?
Field sobriety tests are voluntary and can be declined without an automatic penalty, though the officer may still arrest you based on other evidence. Refusing the evidentiary breath or blood test after an arrest is different: it triggers an automatic license revocation and can be used against you in court.

What happens if I perform poorly on a field sobriety test?
Poor performance can give the officer grounds to request further testing or to make an arrest, but it is not, by itself, proof of impairment; test administration and individual circumstances can both be challenged.

How long will my license be revoked for a DUI?
A first-offense DUI conviction carries a 185-day license revocation. Repeat offenses carry longer revocation periods, and refusing an evidentiary test carries a separate one- or three-year revocation.

Can a DUI conviction be sealed from my record in Nevada?
Nevada law allows certain records to be sealed after a waiting period that depends on the severity of the offense; see our article on how long a DUI stays on your record in Nevada for more detail.

What if I’m arrested for DUI with a child in the car?
Having a minor in the vehicle is an aggravating factor that a judge can consider, and it can lead to enhanced penalties.

What is Nevada’s legal BAC limit?
The legal limit is 0.08% for drivers 21 and older, though a driver with a lower BAC can still be charged if impairment is otherwise evident.

Do DUI penalties increase for repeat offenses?
Yes. Second and third DUI offenses within seven years carry higher fines, mandatory jail time, longer license revocations, and, for a third offense, felony charges.

Is there a legal difference between a DUI and a DWI in Nevada?
Nevada uses “DUI” (driving under the influence) as its statutory term. “DWI” is not used in Nevada’s traffic code, though other states use it to describe similar conduct.

Can I fight a DUI charge if my BAC was under the legal limit?
Yes. An arrest below 0.08% still requires the prosecution to prove impairment, and an experienced attorney can challenge the stop, the testing, or the officer’s observations.
