Summer in the Las Vegas Valley means more cars on the road, more visitors, and more late nights out. It also means heavier impaired-driving enforcement across Southern Nevada. From Memorial Day weekend through Labor Day, the Nevada Highway Patrol and Las Vegas Metro run saturation patrols and DUI checkpoints, especially around holidays and major events on the Strip. Knowing how Nevada law works, and what your rights are, matters before flashing lights ever appear in your mirror.
What Counts as DUI in Nevada
Under NRS 484C.110, it is unlawful to drive with a blood alcohol concentration of 0.08 percent or higher. The limit is stricter for some drivers. Commercial operators face a 0.04 percent limit, and Nevada applies a zero-tolerance standard of 0.02 percent for drivers under 21. You can also be charged for impairment by marijuana, prescription medication, or other substances, even when alcohol is not involved. A reading taken within two hours of driving can support a charge, which is why a drink that felt harmless an hour earlier can still matter at the roadside.
When a DUI causes serious injury or death, the stakes climb sharply. Under NRS 484C.430, driving under the influence that results in death or substantial bodily harm is a category B felony carrying a prison term of 2 to 20 years. A conviction at this level also brings a lengthy license suspension and limits on plea bargaining. These cases are serious for everyone involved, including the people hurt by an impaired driver.
Summer Means the Lake Too
Impaired-driving enforcement in Southern Nevada is not limited to the highway. Lake Mead draws heavy boating traffic all summer, and Nevada treats impaired boating much like impaired driving. Under NRS 488.410, operating a vessel with a BAC of 0.08 percent or higher is unlawful, and a boating-under-the-influence incident that causes substantial bodily harm or death can be charged as a felony. Rangers and game wardens patrol the water during peak weekends, so the same caution you use on the road applies on the lake. Open-container habits that feel normal on a boat can carry the same legal weight as drinking behind the wheel.
Your Rights at a Stop or Checkpoint
If you are stopped, you have the right to remain silent beyond providing your license, registration, and proof of insurance. You are not required to answer questions about where you have been or what you have had to drink. Nevada’s implied-consent law does require chemical testing once you are lawfully arrested for DUI, and refusing an evidentiary test after arrest can lead to license consequences and a forced blood draw under a warrant. Field sobriety tests before arrest are a separate matter, and you may decline those roadside exercises. Stay calm, be polite, and do not volunteer information. What you say at the roadside often becomes the strongest evidence against you later.
New Nevada Traffic Safety Laws to Know in 2026
The 2025 Nevada Legislature passed changes that tightened DUI and related penalties, with provisions phasing in through 2026. Reporting on Senate Bill 309 indicates it raised the minimum jail time for a second DUI within seven years and lowered the BAC level that triggers mandatory alcohol evaluation or treatment. Ignition interlock requirements were also expanded, reducing the discretion some judges had to waive devices for certain offenders. Because penalty details change and exact thresholds matter, confirm anything that affects you directly with the Nevada DMV traffic laws page or the Nevada Legislature website before relying on it.
If You Were Hurt by an Impaired Driver
A DUI arrest is a criminal matter, but the harm done to victims is a separate civil question. The criminal case punishes the driver; it does not put money in your pocket for what the crash cost you. If an impaired driver injured you, you may be able to recover for medical bills, lost income, and pain and suffering through a personal injury claim. Nevada follows modified comparative negligence under NRS 41.141, meaning you can still recover as long as you are not more than 50 percent at fault, though your award is reduced by your share. Most injury claims must be filed within two years under NRS 11.190, so acting promptly protects your rights and helps preserve evidence while it is still fresh.
