What Is Negligence Per Se?
Negligence Per Se is a legal doctrine that may establish a defendant’s breach of duty when the defendant violates a safety law designed to protect people like the injured person. The injured person must still connect the violation to the injury and prove damages. The doctrine does not automatically establish every part of a claim.

How Negligence Per Se Works

Negligence Per Se connects a safety-law violation to the breach element of a negligence claim. The rule must protect a group that includes the injured person, and the injury must relate to the danger the rule addresses. A court may then treat the violation as evidence that the defendant failed to use required care.

Workplace injury claims still require proof of other issues. The injured person must show that the violation contributed to the harm and must document the resulting damages. Duty of care describes the broader obligation to act reasonably, while negligence per se focuses on a particular legal violation. A court may also consider whether the defendant had a valid excuse for the violation.

From the Atlanta Auto Law team
When we review a workplace injury claim, we identify the safety rule that may apply and compare its purpose with the worker’s injury. We also examine causation, available records, and damage evidence because a rule violation alone does not resolve the entire claim.
Negligence Per Se in Practice: A Real-World Example
A warehouse worker suffers an injury after an employer ignores a safety rule designed to prevent that type of hazard. The violation may support negligence per se if the worker belongs to the protected group and the violation contributed to the injury.
