One person died when a vehicle veered off the roadway and struck several trees Saturday afternoon in San Ramon.
At 12:03 p.m., officers responded to a report of a solo vehicle accident on Bollinger Canyon Road, near Harcourt Way, according to police.
A witness reported seeing the involved vehicle traveling west on Bollinger Canyon Road at a high rate of speed. The vehicle left the roadway, striking several trees along the roadway, police said.
The driver was pronounced dead at the scene, police said. No other occupants were inside the vehicle and no other vehicles were involved in the crash.
Police believe speed combined with a wet roadway may have been a factor in the crash.
