A Houston woman’s attempt to save drivers from a speeding ticket landed her something worse: 12 hours in jail.

As she rode her bicycle home from a grocery store last week near downtown Houston, Natalie Plummer noticed police officers pulling over speeders. After she parked her bike and turned one of her grocery bags into a makeshift sign warning drivers about the “speed trap” ahead, an officer drove up and arrested her.

…

Police saw it differently, and arrested Plummer for standing in the street where there a sidewalk was present, a misdemeanor charge.
