Negligence per se in Texas is a doctrine that lets an injured person prove a defendant was negligent by showing the defendant broke a specific safety law written to protect people like the plaintiff from the kind of harm that occurred. Instead of arguing about what a “reasonable person” would have done, the court treats the violated statute as the standard of care. If the violation is unexcused, duty and breach are established, and the case turns on causation and damages.1Legal Information Institute. Negligence Per Se
What Changes When the Doctrine Applies
In an ordinary negligence case, both sides fight over what a careful person would have done in the same situation. Witnesses testify, experts weigh in, and the jury decides whether the defendant met that standard. Negligence per se removes that argument. The legislature has already said what careful behavior looks like by writing it into a statute, ordinance, or regulation. If a driver runs a red light and hits you, the traffic law itself defines the standard, and you don’t need an expert to explain that running red lights is careless.
The jury still decides two things: whether the defendant actually violated the statute, and whether that violation caused the plaintiff’s injuries. What drops out is the debate over the standard of care.
The Two-Prong Test for a Qualifying Statute
Not every broken law will do. Under the Texas Supreme Court’s decision in Nixon v. Mr. Property Management Co., a statute can anchor a negligence per se claim only if the plaintiff satisfies two threshold requirements.2Justia Law. Nixon v Mr Property Management – 1985
- The injured person belongs to the class the statute was designed to protect. Traffic safety laws protect drivers and pedestrians on public roads. Building codes protect occupants and visitors. If you fall outside the intended beneficiaries, the statute won’t support the claim.
- The injury is the kind of harm the legislature was trying to prevent. A law requiring landlords to secure vacant buildings aims at break-ins and assaults on those properties, not unrelated injuries elsewhere.
Both prongs must be met. Statutes written for broad regulatory purposes rather than the protection of a defined group often won’t support the doctrine at all. The judge decides these questions as matters of law before the case ever reaches a jury.
Additional Factors Courts Weigh
Beyond the two prongs, the Texas Supreme Court in Perry v. S.N. laid out further considerations that guide whether a court should adopt a particular statute as the negligence standard. These include whether the statute is the sole source of any duty the defendant owes the plaintiff or merely supplies a standard for an existing common-law duty, whether the statute clearly defines the required conduct, whether applying negligence per se would impose liability without fault, and whether it would produce damages wildly disproportionate to the seriousness of the violation. Courts also look at whether the injury was a direct or indirect result of the violation. These factors give Texas judges real discretion, and they explain why some statutory violations qualify and others don’t.
Excuses That Defeat a Violation
A statutory violation is not the end of the argument. Texas recognizes several excuses, drawn from the Restatement (Second) of Torts, that prevent the doctrine from applying even when a defendant clearly broke the law:
- Incapacity, such as a sudden medical event that made compliance impossible.
- Lack of knowledge, where the defendant neither knew nor should have known of the circumstances requiring compliance.
- Inability to comply despite reasonable diligence, such as a mechanical failure no inspection would have caught.
- A sudden emergency the defendant did not cause, forcing a choice between violating the statute and a greater immediate danger.
- Compliance would have created a greater risk of harm, such as swerving into oncoming traffic to avoid a child in the road.
The defendant carries the burden of proving the excuse. If the court accepts it, the statutory violation cannot serve as the basis for negligence per se, though the plaintiff can still pursue an ordinary negligence claim on the reasonable-person standard.
Causation Is Still on You
Establishing a statutory violation gets you through duty and breach. The rest of the case is causation and damages, and causation has two parts.1Legal Information Institute. Negligence Per Se
Cause in Fact
Would the injury have happened if the defendant had followed the law? That’s the “but-for” question. A driver following too closely rear-ends you: would the collision have occurred with a safe following distance? If not, cause in fact is established. If the accident would have happened anyway, the violation is legally irrelevant no matter how obvious it was.
Foreseeability
The injury also has to be a natural and probable result of the illegal conduct. A driver speeding through a school zone can reasonably foresee hitting a pedestrian. That same driver probably cannot foresee startling a construction worker two blocks away into dropping equipment on a passerby. Foreseeability keeps the doctrine from reaching bizarre chain-reaction outcomes.
An unforeseeable independent event that intervenes between the violation and the final injury can become a superseding cause and cut off liability. Acts that fall within the zone of risk the statute was designed to prevent are treated as foreseeable and will not break the chain. Whether an intervening act rises to the level of a superseding cause is usually a jury question.
Statutes That Anchor Most Texas Claims
Three categories of law produce the majority of negligence per se arguments in Texas courts.
Traffic Laws
The Texas Transportation Code is the single most frequently cited source. Section 545.062 requires drivers to keep enough distance behind the vehicle ahead to stop safely given speed, traffic, and road conditions.3State of Texas. Texas Transportation Code Section 545.062 – Following Distance Section 545.401 makes it an offense to drive with willful or wanton disregard for the safety of people or property.4State of Texas. Texas Transportation Code Section 545.401 – Reckless Driving Speeding, failure to signal, running stop signs, and driving while intoxicated are other common anchors. These statutes fit the doctrine because they set clear behavioral rules and are designed to protect the exact people hurt in traffic crashes.
Building Codes and Property Ordinances
Municipal rules requiring landlords to secure vacant buildings, maintain fire exits, and keep premises reasonably safe regularly support claims against property owners. Texas courts have applied ordinances from cities including Dallas and Houston in cases involving unsecured buildings and inadequate emergency exits.
Federal Safety Regulations
Federal Motor Carrier Safety Administration rules on hours of service, vehicle inspection, driver licensing, and drug testing come up often in trucking cases. Federal regulations do not themselves create a right to sue in civil court, but Texas courts treat them as a standard of care the defendant was obligated to meet.
Comparative Fault Still Cuts Recovery
Texas uses a modified comparative fault system, and it applies even when negligence per se is established. If you are partly at fault, your recovery is reduced by your percentage of responsibility.5State of Texas. Texas Civil Practice and Remedies Code Section 33.012 – Amount of Recovery Twenty percent at fault means a 20% cut to your award.
The threshold is 51%. If a jury finds you more than 50% responsible, you recover nothing.6State of Texas. Texas Civil Practice and Remedies Code Section 33.001 – Proportionate Responsibility This is where negligence per se helps: a clear statutory violation makes it harder for the defense to shift blame onto you. Expect them to try anyway.
Damages You Can Recover
The available damages are the same as in any Texas personal injury case. The doctrine changes how you prove fault, not what you can collect once fault is established.
- Economic damages: medical bills, lost wages, reduced earning capacity, property damage, and other out-of-pocket losses.
- Non-economic damages: pain and suffering, mental anguish, disfigurement, physical impairment, and loss of enjoyment of life. Texas does not cap these in most personal injury cases.
- Exemplary damages: available only for fraud, malice, or gross negligence. Texas caps them at the greater of $200,000, or two times economic damages plus up to $750,000 in non-economic damages.7State of Texas. Texas Civil Practice and Remedies Code Section 41.008 – Limitation on Amount of Recovery
Most of these cases produce compensatory damages only. Punitive damages require conduct beyond ordinary negligence. A driver with unknown brake trouble might trigger negligence per se, but punitive damages would generally require showing the driver knew about the defect and drove anyway.
Deadline to File
You have two years from the date of injury to file a negligence per se lawsuit in Texas.8State of Texas. Texas Civil Practice and Remedies Code Section 16.003 – Two-Year Limitations Period If the injury results in death, the clock runs from the date of death. Miss the deadline and the court will almost certainly dismiss the case regardless of how strong the underlying claim is. Narrow exceptions exist for minors and people with legal disabilities, but the two-year window governs the vast majority of claims.
