Winter road closures.

HB 43 amends Wyoming law to remove the requirement that drivers must "willfully" ignore road closure signs to be charged with a misdemeanor. The bill keeps the same fine range ($750-$1,500) but lowers the legal bar for conviction by eliminating the "willful" element. It directly affects drivers who disregard posted road closures, particularly during winter conditions when closures are common. The law takes effect July 1, 2023, and does not change existing penalties or exceptions.
