You have probably heard the term “negligence,” especially how it applies to personal injury cases. When someone is negligent and causes another person injury, the law says they are responsible for paying for the injured person’s losses and suffering. Proving negligence is not always easy as there are several elements of negligence that must be established. However, there is another legal principle that can make it easier to win a personal injury case.
If the at-fault party caused your accident because they were breaking the law, “negligence per se” is an important legal doctrine that can reduce your burden of proof and make it easier to recover the compensation you deserve.
Here is how the California negligence per se doctrine works and how it can play a crucial role in your personal injury lawsuit.

What Is Negligence Per Se?
Negligence per se is a legal doctrine that presumes someone is negligent if they caused injury to someone else because they violated the law. The legal negligence per se definition is covered by California Evidence Code Section 669.
To win a personal injury case, you must prove the defendant was negligent and their negligence was a major factor in causing your injuries. In a typical case, this requires proving the defendant did not behave in a way a reasonable person would have in the same circumstances. Negligence per se means the defendant’s actions are already presumed to be unreasonable once they violate the law.
Negligence per se example:
Joe strikes another car in an intersection. Rebecca, the other motorist, suffers a fracture and concussion. Police cite Joe for speeding and texting while driving.
Rebecca files a lawsuit against Joe seeking compensation for her injuries. During the trial, Rebecca establishes Joe was negligent per se because he violated laws designed to avoid accidents. She does not need to separately show that Joe’s behavior was unreasonable when he caused the accident.
Negligence Per Se Elements
There are four key elements of negligence per se. To establish negligence per se, you must show:
- The defendant violated a statute or regulation designed to protect people from harm,
- The violation was a proximate cause of your injuries,
- The harm you suffered was the type of harm the statute was designed to prevent, and
- You were a member of the class of people the statute was intended to protect.
To prove the first element, your case must show that the defendant violated a specific statute or regulation. In a car accident, this may involve showing the defendant was speeding, driving under the influence, texting while driving, or committing another type of traffic violation.
To have a valid case for negligence as a matter of law, you must be a member of the class of people the law was designed to protect and you suffered harm the law was intended to prevent. This is straightforward with traffic violations: traffic laws are designed to prevent accidents and injuries to other motorists, pedestrians, cyclists, and passengers.
Finally, you must show that it’s more likely than not that the defendant’s conduct and violation of the law was a proximate cause of your injuries. Proving causation can be straightforward, but it isn’t always clear. There are also two elements to causation: the actual cause and the proximate cause. Actual cause is the action that instigated the accident or harm. Proximate causation means something was a significant factor in causing the accident or harm.
Actual cause is easy to establish in some cases such as a motorist running a red light and hitting someone in the intersection. Proximate cause can be more complicated. To prove the defendant’s violation of the law caused your accident, the court may consider:
- A “but-for” test. But for the defendant’s violation of the statute, would the accident still have happened? If not, this may be enough to show their behavior caused the accident.
- Significant factor test. Was the defendant breaking the law a significant factor in the accident? If the behavior was too far removed from the accident, it may not be considered a cause of the accident.
- Could the defendant have foreseen that their behavior could have caused an accident?
What Is the Difference Between Negligence and Negligence Per Se?
The general standard of negligence requires proving four elements:
- The defendant owed the plaintiff a duty of care,
- The defendant breached this duty,
- The defendant’s breach caused the plaintiff’s injuries, and
- The plaintiff suffered damages.
The doctrine of negligence per se can be used to prove the first two elements of negligence: standard of care and duty of care. By establishing negligence per se, you have shown the defendant owed you a duty of care (you were someone the statute was designed to protect) and they violated the standard of care you were owed by violating the law.
This means it is no longer up to a jury to decide what the standard duty of care was in your circumstances, or how a reasonable person would have behaved. They are also not left to decide if the defendant’s behavior was outside of what a reasonable person should have done.
Negligence Per Se Is a Rebuttable Presumption
It’s important to understand that negligence per se can be rebutted. This means the defendant has the right to submit their own evidence to counter that they were negligent. However, establishing negligence per se shifts the burden of proof from the plaintiff to the defendant who must now prove they were not negligent when they violated the law.
According to Evidence Code Section 669, the presumption of negligence can only be rebutted by proving:
- The defendant violated the statute while acting in a way that could be reasonably expected from someone in a similar scenario who wanted to comply with the law, or
- The defendant was a child and exercising care ordinary for someone of the age, but not if they were engaged in activity normally engaged in by adults only and requiring adult qualifications (such as driving).
Once you have established negligence per se, it isn’t easy to counter. The defendant must provide evidence that a reasonable person could be expected to break the law in the situation. They may submit evidence that:
- They still exercised reasonable care in trying to comply with the statute,
- The defendant had an incapacity that made it reasonable to violate the statute,
- The defendant could not comply with the statute even when using reasonable care,
- Complying with the law had a greater risk of harm to them or others, or
- They were faced with an emergency that they did not cause that required them to violate the law.
While difficult, it isn’t impossible to counter negligence per se. If the defendant’s brakes failed and they could not slow down before the accident, they may not be found negligent per se. A defendant talking on the phone while driving may have a valid excuse if they were reporting an emergency like an injured pedestrian they passed on the street. A driver may also have a valid excuse for speeding if they were transporting someone to the doctor or hospital whose condition suddenly worsened.
How Negligence Per Se Affects California Personal Injury Cases
If you believe the at-fault party was violating the law when your accident occurred, the negligence per se doctrine can make it easier to win your case. By proving negligence per se, you do not need to prove the standard of care and how the defendant’s behavior differed from how a reasonable person would have behaved in the same circumstances. You have also shown that the defendant’s actions were a proximate cause of your accident.
Proving negligence per se alone isn’t enough to win your case. You must still show actual causation, generally the easier aspect of causation to establish, and your damages. However, it makes the burden of proof much lower and shifts the burden to the defendant. If the jury does not find the defendant was negligent per se, they will still consider other evidence in your case to decide if the defendant was still otherwise negligent.
A California personal injury lawyer will present the strongest case possible to establish negligence per se. Depending on the circumstances of your accident, proving the defendant violated the law may involve:
- Police reports
- Citations issued after the accident
- Traffic camera footage
- Eyewitness statements
- Photos of the scene of the accident
- Medical records
- Expert testimony
Juries in California are given California Jury Instruction CACI 418 or “Presumption of Negligence per se” to help them determine when a defendant is negligent as a matter of law. The instructions clearly state that if the plaintiff proves the defendant violated the statute in question and it was a substantial factor in causing the harm, the jury must find the defendant was negligent without a valid excuse.
