 Becky Daggett is the mayor of Flagstaff, Arizona. She's one of about a dozen city leaders who gathered during a meeting of the U.S. Conference of Mayors in Washington, D.C. earlier this year to talk about what they're doing to make their streets safer and how to navigate local pushback. Seattle Mayor Bruce Harrell says his city has been adding no-turn-on-red signs, and drivers are not happy about it.
