In Bagley v. Watson, 478 P.2d 595, 596-97 (Wyo. 1971), the Court was asked to consider the propriety of three instructions that had been offered in the alternative in a highway-collision case.
The first instruction stated that violation of a municipal speeding ordinance "is negligence."
The second instruction described such a violation as creating a rebuttable presumption of negligence. The third instruction told the jury it could consider the violation as evidence of negligence.
While admitting that a review of our case law revealed that the matter needed clarification, the Court sidestepped the question on procedural grounds. Id. at 597.
