One man is struggling for his life after his car veered off Juniper Serra Boulevard early Tuesday morning and struck a tree.
The man had to be extricated from his 2003 Honda sedan by the San Francisco Fire Department, San Francisco Police Officer Albie Esparza said. He remains in the hospital with life-threatening injuries.
The cause of the crash is unknown, though it seems the Honda and a 1996 GMC truck sideswiped one another while travelling south on Juniper Serra at 19th Avenue round 5:22 a.m.
Esparza said investigators are determining if speed was a factor.
“At this point we don’t know if it was,” he said. “We are also looking to see if any other conditions contributed.”
That stretch of road has a speed limit of 45 mph.
Other factors include weather because the Bay Area has been pummeled by rain storm after rain storm since Thursday. Wet weather is expected to continue through the weekend.
Alcohol is not believed to be a factor, Esparza said.
Juniper Serra at 19th was closed shortly after the crash while emergency crews assisted victims, according to Esparza. The road reopened around 9 a.m.
A male and female in the GMC were also transported to the hospital with minor injuries but have since been released.
Police continue to investigate the cause of the crash.
