Nevada DUI Checkpoint Laws

A cop isn't allowed to pull over drivers without probable cause that they're under the influence or committed another crime. But there's one big exception to this rule . . . Nevada DUI Sobriety Checkpoints

Las Vegas police routinely set up drunk driving checkpoints over holiday weekends and during special events in high-traffic areas. At these sobriety checkpoints, police are allowed to stop and arrest you for driving under the influence even if you were driving safely and wouldn't have been pulled over otherwise.

But if you're charged with driving under the influence as a result of a Nevada DUI checkpoint stop, our Las Vegas criminal defense attorneys may be able to get your whole case thrown out if we can show that the sobriety checkpoint didn't adhere to the correct procedures. Keep reading to learn more about roadblock guidelines, and if you've been arrested for drunk driving in Clark County or elsewhere in the state, call us at 702-DEFENSE (702-333-3673) for a free consultation.

What are Nevada DUI Checkpoints?

Also called sobriety checkpoints, drunk driving sobriety checkpoints or DUI roadblocks, Nevada DUI checkpoints are cordoned-off areas on public roads where police can legally stop drivers for no reason and then investigate whether they're under the influence. The supposed purpose of DUI checkpoints is to deter drunk driving.

How do Nevada DUI Checkpoints work?

When you're driving through a Las Vegas sobriety checkpoint, the officers will probably ask you some questions and shine a flashlight into your car to see if you're transporting open alcohol containers. If they believe you're exhibiting intoxicated behavior, you'll be directed to a nearby area to perform DUI field sobriety tests (FSTs) and take a preliminary breath test (PBT). Depending on the results, you may be arrested for driving under the influence or be allowed to leave.

Are Nevada DUI Checkpoints legal?

Only if they're administered properly, and often they're not. In order for an administrative roadblock like a Las Vegas DUI sobriety checkpoint to be valid, law enforcement must follow these strict rules and guidelines:


  • The checkpoint must be established on a highway clearly visible to approaching traffic at a distance of no less than 100 yards in either direction.


  • A sign must be placed near the centerline of the highway displaying the word "Stop" in letters large enough and bright enough to be readable at a distance of no less than 50 yards in either direction.


  • The checkpoint must have at least one flashing red light at the side of the highway, also clearly visible to oncoming traffic at a distance of no less than 100 yards.


  • Warning signs must be placed at the side of the highway no less than a quarter mile from the roadblock so oncoming traffic are notified that a police stop lies ahead. The signage has to be big and bright enough so drivers can see it, and a burning beam light, flare or lantern must be placed near the signs to attract attention. (NRS 484B.570)

If you were arrested at a Las Vegas DUI roadblock and your attorney can show that the police failed to follow any or all of these notice protocols, your case may be dismissed irrespective of whether you were driving under the influence.

Is law enforcement required to publicize Nevada checkpoints in the media?

No. However, law enforcement usually does inform the media about planned DUI checkpoints in Nevada especially if they're being set up during holiday weekends or special events.

Is it illegal to drive through a Nevada DUI checkpoint without stopping?

If you're driving and you see warning signs of an upcoming DUI checkpoint, you're allowed to take any legal detour prior to that checkpoint to avoid going through it. But once you arrive at a checkpoint, you must answer the cops' questions and comply with their requests before you'll be allowed to drive away.

The penalties for traveling through a Nevada administrative DUI roadblock without stopping or for disobeying the officers' orders include the following:


  • If no death, substantial bodily harm or damage to property in excess of $1,000 occurs, the driver may be charged with a gross misdemeanor carrying up to 1 year in jail and/or up to $2,000 in fines.


  • Otherwise, the driver will be charged with a category B felony carrying 1 to six years in prison and/or up to $5,000 in fines. (NRS 484B.580)

    5 A Powerful, Effective Advocate to Have in Your Corner

    In my time of need I called on Neil Shouse and his law firm. It was one of the best decisions I've made in my life. Not only did he step up to assist me, he went the extra mile in every sense of the word. I found Neil to be honest, professional, and tireless in his efforts on my behalf.

    Recently, I made a stupid decision to drink and drive. I was caught speeding in the rural town of Moapa Nevada. I was pulled over and arrested for DUI. My blood alcohol was high and I was nervous about the consequences that could come from the court in that area. Michael took care of my entire case and had my DUI reduced to a reckless driving. This was a huge relief and I am astounded at his work and talent. I also have to compliment his staff, mainly Case Manager John Eisele for being so helpful.

    - Michael S, a DUI client


    I've used Michael for several of my personal tickets, but have reffered all criminal matters to him do to his experience in the Criminal Defense field. All my friends always thank me because he gets excellent results. Michael is a great attorney and dedicated to his clients.

    - Chris, a DUI client


    Michael has helped me with my legal battles for many years. The one thing that always sticks out to me is his honesty and concern for his clients. He has helped us in so many ways, and given jobs to felons who would have otherwise been turned away. Michael is an exceptional human being, and his compassion and care for his clients is top notch. If you have any doubts about his abilities just sit back and watch him work. He is a Master in that courtroom.
