KSL TV SALT LAKE CITY — A coalition aimed at improving the safety of Salt Lake City streets is now seeking to lower the speed limit on city streets, arguing that the current limit doesn't do enough to stop unsafe drivers in residential neighborhoods. The volunteer organization Sweet Streets Salt Lake City began a campaign this week seeking to enact a 20 mph speed limit on roads where people live, work, play, shop or attend school or worship. They began handing out lawn signs reading "20 Is Plenty: Slower Is Safer" and collecting signatures for a petition Wednesday evening. The city currently has an ordinance setting the default speed limit at 25 mph unless otherwise marked. However, Sweet Streets organizers argue that many streets where people are "expected to be in the street among cars" have speed limits higher than 25 mph.
