On November 7, the default city speed limit dropped from 30 to 25 miles per hour. As indicated by the lower sign above, the city also now uses speed cameras (which predated the 30-to-25 reduction) to aid in speed limit enforcement — specifically, to catch drivers going more than 10 miles per hour over the limit. By state law, the cameras can only be used in "school speed zones" (i.e., within a quarter-mile of a school on a street that abuts the school) during school hours and other times of student activity.
