Video captures SF police car slamming into bicyclist

A cyclist riding in a newly painted bike lane was knocked over by a police squad car in San Francisco on Thursday — the city’s Bike to Work Day.

Footage of the collision posted Friday to YouTube shows the squad car pulling over briefly to the right-hand turn lane of Second Street, before swinging back to the left into the adjacent lane and striking the cyclist, who was knocked to the ground after slamming into the cruiser’s driver-side door.

The video shows several seconds of the aftermath of the crash, which happened just before Second Street’s intersection with Mission Street. The officer jumps out of the car and talks to the cyclist, who was laying on the ground for an unknown period of time. The officer called for an ambulance and, per standard protocol, an officer from a different station was called to investigate, authorities said.

The clip was uploaded by tech company Nexar, whose smartphone app records the road as users drive. The phone acts as a dash cam and is primarily used by ride-sharing and taxi drivers, company officials said.

Police disclosed few details about the incident Friday because a report of the collision was not yet completed. The cyclist’s injuries were not life-threatening, said Officer Albie Esparza, a police spokesman.

As with any collision involving a police officer, there will be an administrative and traffic investigation, Esparza added.
