Forty people were injured Friday afternoon in two separate mass transit collisions in San Francisco, authorities said. None of the injuries were life-threatening.
The first crash occurred in Japantown about 1:30 p.m. on the westbound lanes of Geary Boulevard, one of the city's busiest east-west thoroughfares.
The collision occurred when a San Francisco Municipal Transportation Agency bus driver swerved and slammed on the brakes near Webster Street to avoid hitting a dump truck that had stopped suddenly.
The evasive maneuver caused the bus to strike a second dump truck, which was also traveling west on Geary, police Sgt. Danielle Newman said in a statement.
About 20 were injured in the Japantown collision, and 12 were taken to hospitals.
Then, at about 1:50 p.m. and four miles to the southeast, a Muni light rail train collided with an 18-wheeler semi-truck that was on the tracks in Bayview.
The train was headed north on Third Street near Innes Avenue toward downtown when the northbound truck "made an illegal left-hand turn" in front of the light rail train, police spokesman Albie Esparza said.
The train derailed. Twenty people were injured, and 11 of them were taken to hospitals.
