Three people were injured in San Francisco Friday, when a driver struck them as they crossed the street.

According to the San Francsico Police Department, a 70-year-old woman walking with a 7-year-old boy and a 2-year-old boy were crossing Sylvan Drive at Ocean Avenue at 6:03 p.m. Friday when they were struck by a 92-year-old female driver headed west on Ocean Avenue.

In the SFPD report on the incident, they say that the "intersection is not controlled," which means that there aren't any traffic signs or signals. However, a look on Google Maps shows that traffic at Sylvan has a stop sign, while traffic on Ocean does not.

All three pedestrians were left with injuries police say are life threatening, and were transported to San Francisco General Hospital for treatment.

Multiple media reports characterize the intersection as without crosswalks, but we know better — as we've discussed multiple times, unless otherwise marked, corners are actually considered crosswalks in the state of California. That said, it's unclear if the pedestrians in question were crossing at a corner, and a call to SFPD for clarification was not returned at publication time.

Police say that the driver was not arrested at the scene, and did not provide details on if she'd be cited. As of Wednesday, an update on the condition of the victims was not available.
