Jefferson County, MO Public Conduct: Jaywalking (2026)

060 of the county's Traffic Code, titled 'Prohibited Crossing,' bars pedestrians from crossing at any place between adjacent intersections where traffic control signals are in operation, unless the crossing is inside a marked crosswalk. 040, still requires pedestrians to cross at right angles to the curb by the shortest path to the opposite curb, except when using a crosswalk. 050 flips that duty onto the pedestrian anywhere else, requiring the walker to yield to all vehicles when crossing outside a marked or unmarked intersection crosswalk, and again at any point where a pedestrian tunnel or overhead crossing has been built.

030 adds that once in a crosswalk, pedestrians should keep to the right half whenever practicable. Together the sections mean a pedestrian who steps off the curb mid-block on a signalized stretch, or who cuts diagonally across an intersection instead of crossing at right angles, has crossed unlawfully and forfeits the right-of-way protection a marked crosswalk would otherwise provide.
