A crash between a car and a motorcycle in San Luis Obispo on Wednesday afternoon left a 24-year-old rider with what authorities describe as life-threatening injuries and blocked a major eastbound lane for more than two hours. The incident disrupted the afternoon commute and prompted a specialized collision probe.
Emergency crews were dispatched to the intersection of Foothill Boulevard and Casa Street after the collision. Eastbound Foothill — between California Boulevard and Santa Rosa Street — was closed while responders worked the scene, reopening to traffic after several hours.

The motorcyclist was transported to a nearby hospital with critical injuries. A 58-year-old motorist who was driving the other vehicle cooperated with officers at the scene; both that driver and a passenger were later taken to hospital with injuries described as moderate.
Police said there were no immediate signs that alcohol or narcotics played a role. Detectives have continued gathering evidence and witness statements as the inquiry remains active.
Who is handling the investigation
San Luis Obispo’s law enforcement assigned the case to the Severe Collision Investigative Detail (SCID), a unit of trained crash reconstruction specialists, alongside department detectives. SCID teams typically map vehicle paths, collect scene measurements and review available video to determine contributing factors.
