relative to local authorities' power to declare a reasonable and safe speed limit.

SB 630 lowers the minimum speed limit local authorities can set in certain areas from 25 mph to 20 mph. It directly affects towns and cities by allowing them to establish 20 mph limits in non-urban zones and business/residential districts, where previously the minimum was 25 mph. The bill modifies existing law (RSA 265:63) to reflect this change, with no estimated cost to the state or local governments. The Department of Transportation requested this change to support safer speed management in communities.
