At least nine cities in Texas have ratified 3-foot passing bill, following Texas Gov. Rick Perry’s veto in 2010 of a statewide 3-foot law that had gained legislature approval but faced opposition from special interests.
Montgomery, Alabama also passed a 3-foot passing ordinance for the city in 2012.
