Whether an unexcused violation of a safety statute requiring lights on a vehicle is merely evidence of negligence or negligence as a matter of law.
Holding
It is negligence as a matter of law, not merely evidence from which a jury may choose to infer negligence.
Reasoning
The lighting statute was enacted to protect other travelers on the highway. When a person willfully or heedlessly omits a safety measure that the Legislature has prescribed for the protection of others, that person falls below the legal standard of care.
The Court treated the statutory breach and negligence as coalescing under these circumstances. This was not a case involving a person outside the statute's protected class, nor did it involve only a local ordinance; Herzog was precisely the kind of highway traveler whom the lighting requirement was designed to protect.
The trial court therefore erred by allowing jurors to decide, in their discretion, whether Martin's unexcused failure to display lights was innocent or culpable. Jurors have no authority to relax a statutory duty enacted to safeguard human life.
