Negligence Per Se Explained: How Statutory Violations Affect Your Claim

What Is Negligence Per Se?

Negligence per se is a legal doctrine that establishes a defendant's negligence automatically when they violate a statute, regulation, or ordinance that was designed to protect the public. Under this doctrine, the violation of the law itself serves as proof of negligence, eliminating the need for the plaintiff to prove that the defendant failed to act as a reasonably prudent person would have under the circumstances.

In a standard negligence case, the plaintiff must prove four elements: duty, breach, causation, and damages. The duty and breach elements require showing that the defendant owed a duty of care and failed to meet that standard. Negligence per se simplifies this process by replacing the duty and breach elements with proof that the defendant violated a specific law. If the plaintiff can show that the defendant violated a statute designed to prevent the type of harm that occurred, the defendant is automatically considered negligent.

This doctrine is particularly powerful in personal injury cases because it removes the subjective question of whether the defendant acted reasonably and replaces it with the objective question of whether the defendant violated the law. Traffic violations, building code violations, workplace safety violations, and other statutory breaches can all serve as the basis for negligence per se claims.

Elements of Negligence Per Se

To establish negligence per se, the plaintiff must prove several specific elements that connect the statutory violation to the injury.

Violation of a Statute or Regulation

The first element requires proof that the defendant violated a specific statute, regulation, or ordinance. This can include traffic laws, building codes, health and safety regulations, workplace safety standards, and other legal requirements. The violation must be clearly established through evidence such as police citations, inspection reports, or regulatory findings.

The Statute Was Designed to Prevent the Type of Harm

The plaintiff must show that the statute the defendant violated was designed to prevent the specific type of harm that occurred. For example, speed limit laws are designed to prevent traffic accidents, so a speeding violation can establish negligence per se in a car accident case. However, a violation of a parking regulation would not establish negligence per se in a collision case because parking regulations are not designed to prevent collisions.

The Plaintiff Is Within the Protected Class

The plaintiff must be a member of the class of persons the statute was designed to protect. For example, child labor laws are designed to protect minors, so a minor injured due to a child labor violation can invoke negligence per se. An adult injured in the same circumstances might not be able to use this doctrine because they are not within the protected class.

The Violation Caused the Injury

The plaintiff must prove that the statutory violation was a proximate cause of their injury. Even if the defendant violated a statute, negligence per se does not apply if the violation did not cause or contribute to the plaintiff's harm. The causal connection between the violation and the injury must be established.

Common Examples of Negligence Per Se

Negligence per se arises in many different types of personal injury cases.

Traffic Violations

Traffic law violations are the most common basis for negligence per se claims. Running a red light, speeding, failing to yield, driving under the influence, texting while driving, and other traffic violations can establish automatic negligence when they cause an accident. A police citation for the violation provides strong evidence, though a citation is not always required.

Building Code Violations

Violations of building codes and housing regulations can establish negligence per se in premises liability cases. Missing handrails, inadequate lighting, structural defects, fire code violations, and other building code violations that cause injuries can serve as the basis for negligence per se claims against property owners and builders.

Workplace Safety Violations

Violations of OSHA regulations and other workplace safety standards can establish negligence per se in workplace injury cases. Missing machine guards, inadequate fall protection, failure to provide personal protective equipment, and other safety violations that cause worker injuries can support negligence per se claims against employers and third parties.

Product Safety Violations

Manufacturers who violate product safety regulations, such as Consumer Product Safety Commission standards, may be subject to negligence per se claims when their products cause injuries. Failure to include required safety features, inadequate warnings, and violations of manufacturing standards can all serve as the basis for these claims.

Alcohol Service Violations

Bars and restaurants that serve alcohol to visibly intoxicated patrons or to minors in violation of state liquor laws may be subject to negligence per se claims when the intoxicated patron causes an accident. These claims, often brought under dram shop laws, use the liquor law violation to establish the establishment's negligence.

Animal Control Violations

Violations of leash laws, dangerous dog ordinances, and other animal control regulations can establish negligence per se in dog bite and animal attack cases. A dog owner who violates a leash law and whose dog attacks someone may be automatically negligent under this doctrine.

How Negligence Per Se Affects Your Settlement

The application of negligence per se can significantly impact the value and outcome of your personal injury claim.

Simplified Liability Determination

When negligence per se applies, the liability determination is simplified because the plaintiff does not need to prove that the defendant failed to act reasonably. The statutory violation itself establishes negligence, making it more difficult for the defendant to dispute liability.

Stronger Negotiating Position

A negligence per se claim gives you a stronger negotiating position with the insurance company because the liability issue is largely resolved. Insurance companies are more likely to offer fair settlements when they know that liability is clear and that a jury would likely find the defendant negligent based on the statutory violation.

Higher Settlement Values

Cases with clear liability through negligence per se tend to settle for higher amounts because the insurance company cannot effectively dispute fault. When liability is contested, insurance companies often reduce their offers to account for the risk that the plaintiff might not prevail at trial. Negligence per se eliminates much of this risk.

Impact on Comparative Fault

In comparative fault states, negligence per se can affect the allocation of fault between the parties. A defendant who violated a statute may be assigned a higher percentage of fault than they would in a standard negligence case, resulting in greater compensation for the plaintiff.

Defenses to Negligence Per Se

Despite the power of negligence per se, defendants have several defenses available.

The Violation Did Not Cause the Injury

The most common defense is that the statutory violation did not cause the plaintiff's injury. Even if the defendant violated a law, they are not liable under negligence per se if the violation was not a proximate cause of the harm. For example, a driver who was speeding but whose speed did not contribute to the accident may argue that the violation did not cause the injury.

Compliance Was Impossible

A defendant may argue that compliance with the statute was impossible under the circumstances. For example, a driver who suffered a sudden medical emergency and ran a red light may argue that compliance was impossible due to the medical condition.

Emergency Circumstances

Similar to the impossibility defense, a defendant may argue that emergency circumstances justified the statutory violation. A driver who exceeded the speed limit to avoid a hazard in the road may argue that the emergency justified the violation.

The Statute Does Not Apply

The defendant may argue that the statute the plaintiff relies on does not apply to the specific situation, does not protect the class of persons to which the plaintiff belongs, or was not designed to prevent the type of harm that occurred.

Comparative Fault

In comparative fault states, the defendant may argue that the plaintiff's own negligence contributed to the injury, reducing the defendant's share of liability. Even when negligence per se applies, the plaintiff's comparative fault can reduce their recovery.

Negligence Per Se vs. Standard Negligence

Understanding the differences between negligence per se and standard negligence helps clarify when each applies.

Standard of Care

In standard negligence, the standard of care is the behavior of a reasonably prudent person under the circumstances. This is a flexible, subjective standard that requires the jury to evaluate the defendant's conduct. In negligence per se, the standard of care is defined by the statute, providing a clear, objective benchmark.

Burden of Proof

In standard negligence, the plaintiff bears the burden of proving that the defendant breached the duty of care. In negligence per se, the plaintiff's burden is simplified to proving the statutory violation, the causal connection, and the damages.

Rebuttable Presumption vs. Conclusive Proof

In most jurisdictions, negligence per se creates a rebuttable presumption of negligence rather than conclusive proof. This means the defendant can present evidence to rebut the presumption, such as showing that compliance was impossible or that emergency circumstances existed. In a few jurisdictions, negligence per se is conclusive, meaning the defendant cannot rebut the presumption.

Applicability

Standard negligence applies to all situations where a duty of care exists. Negligence per se applies only when a specific statute has been violated. If no statute applies to the defendant's conduct, the plaintiff must rely on standard negligence principles.

State Variations in Negligence Per Se

The application of negligence per se varies significantly from state to state.

States That Recognize Negligence Per Se

Most states recognize negligence per se in some form, though the specific requirements and applications vary. Some states apply the doctrine broadly to any statutory violation, while others limit it to specific types of statutes or violations.

States with Rebuttable Presumption

In most states, negligence per se creates a rebuttable presumption of negligence. The defendant can present evidence to overcome the presumption, such as showing that the violation was excusable or that it did not cause the injury.

States with Conclusive Presumption

A few states treat negligence per se as conclusive proof of negligence, meaning the defendant cannot rebut the presumption once the statutory violation is established. In these states, the only remaining issues are causation and damages.

States That Reject Negligence Per Se

A small number of states do not recognize negligence per se as a separate doctrine. In these states, a statutory violation may be considered as evidence of negligence but does not automatically establish it.

Practical Tips for Using Negligence Per Se

Several practical strategies can help you effectively use negligence per se in your personal injury claim.

Identify Applicable Statutes

Work with your attorney to identify all statutes, regulations, and ordinances that the defendant may have violated. The more violations you can establish, the stronger your negligence per se claim.

Obtain Documentation of the Violation

Gather evidence documenting the statutory violation, such as police citations, inspection reports, regulatory findings, and witness testimony. Official documentation of the violation is the strongest evidence for a negligence per se claim.

Connect the Violation to Your Injury

Establish a clear causal connection between the statutory violation and your injury. Medical records, expert testimony, and accident reconstruction analysis can help demonstrate that the violation caused or contributed to your harm.

Anticipate Defenses

Prepare to counter the defenses that the defendant may raise, including arguments that the violation did not cause the injury, that compliance was impossible, or that emergency circumstances existed.

Conclusion

Negligence per se is a powerful legal doctrine that can significantly strengthen your personal injury claim by establishing the defendant's negligence through proof of a statutory violation. Understanding how this doctrine works, when it applies, and how it affects your settlement can help you make informed decisions about your case. Whether your claim involves a traffic violation, a building code violation, a workplace safety violation, or another statutory breach, negligence per se can simplify the liability determination and increase the value of your claim.
