Authorizes local school districts and municipalities to determine and establish school speed limits

This bill allows local school districts and municipalities to set their own speed limits near schools. It specifies that school speed limits can be as low as 15 mph for up to 1,320 feet along highways passing school entrances or exits. The bill amends vehicle and traffic laws to give these local entities authority to establish and maintain such limits, replacing the previous state-level standard for school zones. It does not change the general 55 mph speed limit elsewhere, only clarifies local control for school areas.
