reducing the minimum allowable speed limit on locally controlled roads.

SB 559 lowers the minimum speed limit on locally controlled roads from 25 mph to 20 mph in certain areas, including outside urban districts and within business or urban residential zones. Local authorities must base any speed limit reduction on engineering or traffic studies before implementing it. The bill does not require new funding or change existing enforcement, as it only modifies the minimum limit threshold in state law. This affects municipalities and town officials responsible for setting speed limits on local roads.
