Overturned Car in San Geronimo

A 71-year-old man from Berkeley, Donald Grether, veered left across traffic on Sir Francis Drake Boulevard at San Geronimo Road and flipped over at 1:50 p.m. on Wednesday, Oct. 19.

Grether was traveling eastbound on Sir Francis Drake Boulevard at approximately 45 mph when his Subaru veered left into oncoming traffic and hit a redwood tree on the north side of the road, according to CHP Officer Chris Rardin.

The collision, reportedly, caused the car to flip over and come to rest on its roof, blocking both lanes of traffic.

CHP responded and extracted Grether from the vehicle, where he was pinned inside. He and the passenger, his wife, Rebecca, 69, were transported to Marin General for moderate injuries, said the CHP.

The road was reopened at 3:20 p.m.

The cause of the accident is still under investigation. DUI is not suspected as a cause.
