FATAL CRASH ON SR-116 OUTSIDE GUERNEVILLE

On October 19, 2026, at approximately 12:17 a.m., Santa Rosa CHP officers responded to a report of a vehicle on fire following a crash on westbound State Route 116 at Redwood Drive west of Guerneville.

The preliminary investigation indicates a Mercedes was traveling westbound on SR-116 at an unknown high rate of speed when the driver lost control of the vehicle. The Mercedes left the roadway and collided with a rock and a tree, sustaining major damage before catching fire. Fire personnel responded and extinguished the flames.

The driver was located deceased inside the vehicle. Two adult male passengers sustained major injuries but were able to exit the vehicle. They were transported to Santa Rosa Memorial Hospital for treatment.

The cause of the crash remains under investigation, including whether alcohol was a contributing factor.

Anyone with information regarding this crash is asked to contact the Santa Rosa CHP Area office at (707) 806-5600. Questions regarding the deceased should be directed to the Sonoma County Sheriff Coroner’s office.

🌊 SR-1 offers some incredible coastal views, but traveling over 90 mph leaves little room for error. Narrow, winding roads demand safe speeds and your full attention.

CHP officers are out patrolling our roadways to help keep everyone safe. Enjoy the coast, respect the road, and slow down.
