What Is Negligence Per Se in Nevada and How Does It Help Your Case?

In a standard Nevada personal injury claim, you must prove four things: the defendant had a duty of care, they breached that duty, the breach caused your injury, and you suffered damages. Proving breach — that the defendant failed to act as a reasonable person would — typically requires presenting evidence and arguing that the defendant’s conduct fell below an acceptable standard. This is often contested territory.

Negligence per se is a doctrine that simplifies the breach element significantly. When it applies, the defendant’s violation of a specific law or regulation designed to protect people in your situation is treated as proof of breach without requiring further argument about whether their conduct was reasonable. This shifts the debate to causation and damages rather than the threshold question of fault.

What Negligence Per Se Means in Practice

The term per se is Latin for ‘by itself’ or ‘in itself.’ Negligence per se means that the negligence is established by the very fact of the legal violation. A defendant who ran a red light and hit your vehicle has, in violating NRS 484B.307, automatically established the breach element of your negligence claim — because traffic signals exist precisely to protect people on the road from being struck by vehicles that should have stopped. You do not need to argue about whether running a red light was unreasonable. The legislature has already made that determination by making it illegal.

Nevada courts recognized the negligence per se doctrine in Barnes v. Delta Lines, Inc., 99 Nev. 688 (1983), and it has been applied consistently in personal injury cases involving statutory violations since then.

The Four Elements of a Nevada Negligence Per Se Claim

To establish negligence per se in a Nevada personal injury case, four elements must be proven:

1. A Statute or Regulation Exists to Protect a Class of Persons

The violated law must have been enacted for a protective purpose. Traffic laws protecting road users, building codes protecting occupants, safety regulations protecting workers and members of the public — all of these qualify. A law that exists for purely administrative or revenue purposes, without a clear protective intent, would not support a negligence per se claim.

2. The Plaintiff Belongs to the Class the Statute Was Designed to Protect

You must be within the class of people the law was intended to shield. If a driver violates a traffic law that exists to protect other drivers and pedestrians, and you are a driver or pedestrian who was injured as a result, you belong to the protected class. This element is straightforward in most traffic and premises liability cases.

3. The Defendant Violated the Statute

The violation must be established. In traffic cases, a citation issued to the at-fault driver is strong evidence of the violation, but it is not strictly required. A police report documenting the violation, witness testimony, physical evidence of the vehicle’s position or speed, and surveillance footage can all establish that the defendant violated the law even without a formal citation.

4. The Violation Caused the Plaintiff’s Injuries

The statutory violation must have been a proximate cause of the harm. If a driver was technically speeding but the crash would have occurred at any speed due to entirely different causes, the negligence per se claim may fail on causation. The violation must connect logically and factually to the injury that resulted.

Common Nevada Traffic Violations That Support Negligence Per Se Claims

Traffic law violations are the most frequent basis for negligence per se claims in Nevada personal injury cases. Laws that commonly arise include:

Running a red light or stop sign under NRS 484B.307 — perhaps the clearest example of negligence per se, since traffic signals exist to prevent exactly the kind of intersection collisions they produce when violated

Driving under the influence under NRS 484C.110 — Nevada’s DUI laws explicitly exist to protect other road users, making a DUI violation that causes an accident a textbook negligence per se case

Speeding in violation of the basic speed law under NRS 484B.600 — speed limits exist to protect other drivers and pedestrians from the increased danger of higher-speed collisions

  • Failure to yield the right of way — yield and right-of-way laws exist to prevent intersection and merge conflicts

Following too closely under NRS 484B.127 — the following distance requirement exists to protect vehicles ahead from rear-end impacts

Failure to yield to pedestrians in a crosswalk under NRS 484B.283 — protecting pedestrians using marked and unmarked crossings — see our pedestrian accident page for more on crosswalk claims

Unsafe passing of a cyclist under NRS 484B.270 — protecting cyclists from insufficient clearance during passing maneuvers — see our bicycle accident page for more

  • Violating cell phone hands-free laws — enacted to prevent distracted driving injuries

Negligence Per Se Outside the Traffic Context

While traffic violations generate the most common negligence per se claims, the doctrine applies wherever a safety statute is violated and someone in the protected class is injured. Examples beyond the traffic context include:

  • Building code violations that create unsafe conditions causing a tenant’s or visitor’s injury

FMCSA regulatory violations by commercial truck drivers or carriers, such as hours of service violations that contribute to a fatigued-driving crash — see our truck accident page for how FMCSA violations are used in commercial truck cases

  • OSHA workplace safety violations that cause injury to a worker or a member of the public

Nevada’s boating law violations under NRS Chapter 488, such as operating a vessel while intoxicated, that cause injury to passengers or other boaters

Nevada’s dram shop statute, NRS 41.1305, which creates liability for licensed vendors who serve alcohol to visibly intoxicated persons who then injure third parties

Negligence Per Se Is a Rebuttable Presumption

An important limitation of the negligence per se doctrine in Nevada is that a statutory violation creates a rebuttable presumption of negligence, not an irrebuttable one. The defendant can present evidence that their violation was excused or justified under the circumstances.

Nevada courts recognize that compliance with a statute may sometimes be impossible or may create greater danger than the violation itself. The standard for excuse is what a reasonable person would have done in the same circumstances. In practice, excuses for traffic law violations are rarely persuasive when the violation is a straightforward one like running a red light or driving while intoxicated.

How Negligence Per Se Affects Settlement Negotiations

The practical value of a negligence per se finding goes beyond the courtroom. In settlement negotiations, a clear statutory violation by the at-fault driver shifts leverage significantly toward the injured plaintiff. An insurer whose client ran a red light and was cited for it has substantially less room to contest liability than one defending a disputed-fault case. This is one reason that securing a police report documenting a traffic citation, preserving surveillance footage that captures the violation, and retaining witness accounts are so important in the immediate aftermath of an accident. See our page on Nevada personal injury settlement process for more on how liability clarity affects settlement dynamics.
