An elderly San Francisco man was killed after his car hit a tree in Saratoga on Saturday evening, according to the California Highway Patrol.

The 70-year-old man was traveling eastbound in the driveway of 14831 Pierce Road at an unknown speed when he failed to negotiate a curve to the left at about 5:45 p.m., CHP officials said.

The driver’s 1969 Volkswagen Beetle veered to the right off of the roadway and crashed into a large tree on the right shoulder, according to the CHP.

After the crash, the Volkswagen came to a stop on its wheels with the front of the car against a tree.

The 70-year-old was not wearing his seatbelt and it appears he was killed instantly, CHP officials said.

It is unknown whether alcohol was a factor in the crash.

The CHP has not yet released the name of the victim.
