Legislation that Saves Lives: AB43 and AB413

Cities worldwide have witnessed tremendous success in life-saving measures such as speed reduction (AB43) and enhanced intersection visibility (AB413).

We adamantly urge the city to promptly implement these laws, ensuring the safety of all San Diegans whether walking, biking, rolling, or driving! With just one year remaining to achieve the City of San Diego’s Vision Zero goals, time is of the essence.

Next steps:

  • AB43: Expand speed reductions to school zones citywide. This year, the Vision Zero Coalition — including groups like the San Diego County Bicycle Coalition, Families for Safe Streets San Diego, Climate Action Campaign, Circulate San Diego, SanDiego350, and BeautifulPB — submitted a $150,000 budget request to fund this next phase. AB43 allows the city to set school zone speed limits at 15 mph within 500 feet of a school, and 25 mph within 500–1,000 feet. Speed matters: the chances of dying as a pedestrian when struck by a car are 1.8% at 15 mph, 8% at 20 mph, 20% at 30 mph, and a devastating 46% at 40 mph. Slowing down saves lives — and this simple, low-cost change would make a major difference for San Diego's kids and families.

  • AB413: Paint as many curbs as possible and bundle daylighting projects with upcoming work orders to move faster. Over time, we should transform these cleared curb spaces into bike-share docks (p.s. bring back bikeshare!), parklets, murals, or bulb-outs reinforced with flexposts or hard infrastructure to protect people walking and biking. Done right, these changes won't just make intersections safer — they'll help create more vibrant, people-centered neighborhoods.
