UPDATE (2:25 p.m. Saturday) - CHP says one person has died in a fatal crash on Highway 101 northbound near Paso Robles Friday night.
Officials say 35-year-old Jose Toral of Atascadero died after he crashed into the car of 59-year-old John Hutchings, who has minor injuries from the incident.
Authorities do not know why Toral collided with Hutchings' vehicle.
Shortly after 11 p.m. Friday, Toral drove on Highway 101 northbound near Main Street in Paso Robles behind Hutchings, according to CHP.
CHP officials say, for unknown reasons, Toral turned his 1998 Ford Explorer to the right while approaching Hutchings' 2015 Honda CRV in the leftmost lane. Afterwards, the front of Toral's car collided with the rear of Hutchings' vehicle.
The collision propelled Hutchings' car in a northeast direction and eventually collided with a guardrail.
Toral's vehicle propelled eastward, where it traveled off the roadway and crashed into a roadside sign and a tree. The car came to a rest on its roof.
Police say alcohol has not been ruled out as a contributing factor to the collision.
