Florida Statutes sec. 316.189 states, "With respect to residence districts, a municipality may set a maximum speed limit of 20 or 25 miles per hour on local streets and highways after an investigation determines such a limit is reasonable. It shall not be necessary to conduct a separate investigation for each residence district."
Around the world, cities are lowering speed limits to 20 mph for greater safety.
If those living on a residential street want a 20 mph limit, municipalities should accommodate the request. The Florida legislature should amend the statute to include counties.
