What Is Negligence Per Se in Nevada — and How It Strengthens Your Claim
Negligence per se in Nevada is a legal shortcut that can make proving your case dramatically easier: when someone injures you by breaking a safety law designed to protect people like you, that violation can establish their fault almost automatically. Instead of arguing about whether the person acted carelessly, you point to the law they broke. It’s one of the most powerful tools in a Nevada injury claim.
Here’s how it works, and when it can strengthen your case.
The basic idea
In an ordinary negligence case, you have to prove the other person failed to act as a reasonably careful person would have — a judgment call the jury weighs. Negligence per se removes much of that argument. Nevada courts have long recognized that when a defendant violates a statute or regulation meant to protect a certain class of people, that violation itself can establish the duty and breach elements of negligence (as in Barnes v. Delta Lines).
In plain terms: the lawbreaker doesn’t get to argue they were being careful. Breaking the safety law is the carelessness.
The four elements
To use negligence per se in Nevada, four things generally must be true:
- A law or regulation existed that was designed to protect a class of people.
- You belong to that protected class.
- The defendant violated that law.
- The violation caused your injury — and your injury is the type the law was meant to prevent.
The classic example is a drunk-driving crash: DUI laws exist to protect people on the road, so a driver who injures you while intoxicated is negligent per se. The same logic reaches far beyond DUIs.
Where it shows up in Nevada injury cases
Negligence per se strengthens claims across many practice areas:
- Car accidents — running a red light, speeding, illegal turns, or prohibited handheld phone use all violate traffic safety statutes designed to protect other drivers and pedestrians.
- Dog bites — a leash-law violation can establish an owner’s fault, which is why an off-leash dog that bites someone can create liability even for a first bite.
- Premises liability — violating a building code or a pool-barrier requirement can be negligence per se when someone is hurt as a result.
In each case, the broken law does part of the work of proving fault for you.
What negligence per se does not do
It’s a powerful tool, but not a complete case. Establishing negligence per se generally proves duty and breach — it does not automatically prove that the violation caused your injury or the extent of your damages. You still have to connect the violation to your harm and prove what that harm was worth. Insurers know this, and they often concede the violation while fighting hard on causation and damages.
There’s also a defense: a violation can be excused if breaking the law was what a reasonable, prudent person would have done under the circumstances — for example, swerving to avoid a child who darted into the road. That’s a narrow exception, but it exists.
Why it matters for your claim
Negligence per se can shift the entire posture of a case. When the other side broke a clear safety rule, the argument moves from “were they careless?” to “how much did their violation cost you?” — a far stronger position. It also pairs directly with Nevada’s comparative negligence rule: establishing the other party’s statutory violation helps anchor fault where it belongs and pushes back against attempts to blame you.

What are the elements of negligence per se in Nevada? Four elements generally apply: a law existed to protect a class of people, you belong to that class, the defendant violated the law, and the violation caused an injury of the type the law was meant to prevent.
Does negligence per se automatically win my case? No. It generally establishes duty and breach, but you still have to prove the violation caused your injury and prove the amount of your damages. A violation can also be excused if breaking the law was reasonable under the circumstances.
What are examples of negligence per se? Common examples include drunk driving, running red lights, speeding, leash-law violations in dog bite cases, and building- or pool-code violations in premises liability cases.
