California Assembly Bill No. 43 (AB 43) provides cities more flexibility when establishing speed limits in business and residence districts. AB 43 allows for reduction of speed limits after considering safety, land uses, and concentration levels of bicyclists and pedestrians, especially those from vulnerable groups such as children, seniors, persons with disabilities, and individuals experiencing homelessness. AB 43 also allows lowered speed limits on sections of roadways in a “business activity district”, such as neighborhood downtowns. AB 43 went into effect in 2022 and revised the process by which traffic surveys are prepared.
