Existing law authorizes local authorities, for those highways under their jurisdiction, to adopt rules and regulations by ordinance or resolution on various matters, including prohibiting the use of particular highways by certain vehicles and prohibiting entry to, or exit from, or both, from any street by means of islands, curbs, traffic barriers, or other roadway design features to implement the circulation element of an adopted general plan, as specified. Existing law also authorizes a local authority to adopt an ordinance to implement a slow streets program, which may include closures to vehicular traffic or through vehicular traffic of neighborhood local streets with connections to citywide bicycle networks, destinations that are within walking distance, or green space.

This bill would additionally authorize local authorities to adopt rules and regulations by ordinance or resolution to prohibit any person, business, or other entity having ownership or control of a navigation program from providing directions to a driver that would include any of the streets in a slow streets program, and would require the local authority to notify the person, business, or other entity having ownership or control of a navigation program of the streets in a slow streets program.
