SAN FRANCISCO (CBS SF) – Advocates are calling for San Francisco city leaders to declare a state of emergency on traffic safety, following the deaths of two pedestrians on city streets in the past week.

Walk San Francisco, along with the San Francisco Bicycle Coalition and Supervisor Matt Haney, are expected to rally in front of City Hall Tuesday morning, less than two days after the driver of a Tesla hit two tourists at the intersection of Taylor and O’Farrell streets.
