The two-car crash was reported at about 5:20 a.m. on southbound Junipero Serra Boulevard just south of 19th Avenue, near Interstate Highway 280, San Francisco police Lt. Troy Dangerfield said.
The cars involved, a 1996 GMC and 2003 Honda, somehow sideswiped one another, and both vehicles went off the roadway. One vehicle hit a tree and the other went down an embankment, Dangerfield said.
A male and female inside the GMC suffered minor injuries and were taken to a hospital, he said.
The driver of the Honda suffered some sort of leg injuries, not believed to be life-threatening, and was also taken to a hospital, Dangerfield said.
The cause of the crash remains under investigation, he said.
