CA AB43

Authorizes local authorities to consider safety of vulnerable pedestrian groups (children, seniors, persons with disabilities, homeless individuals) when conducting engineering and traffic surveys to set speed limits.

Establishes a 25 mph prima facie speed limit on state highways in business or residence districts and allows Caltrans to adjust this limit, matching authority previously limited to local streets.

Allows Caltrans and local authorities to set speed limits as low as 15 or 20 mph (previously minimum was 25 mph) on state highways and local streets, with violations subject to warning citations for first 30 days of implementation.

Permits local authorities to lower speed limits an additional 5 mph on safety corridors or areas with high pedestrian/bicyclist activity (effective June 30, 2024 or when online traffic infraction tool is available).

Authorizes local authorities to set 25 or 20 mph speed limits in business activity districts meeting specific criteria, and extends speed limit enforcement validity from 7 to 14 years when a registered engineer confirms no significant roadway changes have occurred.
