Update, 5 p.m.:
Officials say the driver and the passenger in the truck were two Arroyo Grande High School students.
CHP Officer Mike Poelking said the two 17-year-old students were heading eastbound on Grand Avenue when they turned onto the highway. During their acceleration, the car spun out of control and drove over the edge of the road into a culvert, where it hit a large tree branch, he said.
“To me it looks like a combination of speed and wet roadway,” Poelking said, noting that cars often lose control on the ramps in the area due to high speeds.
Five Cities Fire Chief Steve Lieberman told The Tribune the pair appeared to be on their way back to school from lunch when the crash occurred.
Arroyo Grande High School principal Dan Neff said the high school has an open campus policy for upper classmen, allowing them to leave the school grounds during lunchtime.
“Our thoughts are with the students involved in the accident and their families,” Neff said in an email statement to The Tribune on Thursday afternoon. “We are here to support all of our students and there is counseling available for any student that may need it.”
