A teenage boy who crashed his car into San Luis Creek on Tuesday evening is believed to have been driving under the influence of alcohol, police said.
The 16-year-old was taken to the hospital after the crash. He remained there early Wednesday morning, so police were going to refer the potential felony DUI case to the District Attorney's Office.
The crash was first reported at 7 p.m. Emergency personnel found the blue 1995 Honda Accord on is roof, partially submerged in the creek near San Luis Drive and California Boulevard.
The three juvenile passengers - 16- and 17-year-old boys from San Luis Obispo and a 17-year-old girl from Atascadero - had already gotten out of the vehicle. The driver sustained a serious leg injury and remained in the creekbed.
The boy was removed from the creek with an extended aerial ladder from a fire truck.
Most of the occupants of the vehicle were wearing seatbelts, police said, preventing what could have been more serious injuries.
Names of the driver and passengers have been withheld because they are juveniles.
A Honda Civic carrying four teens crashed into San Luis Obispo Creek at the intersection of California Boulevard and San Luis Drive just before 7 p.m. Tuesday.
When the San Luis Obispo Fire Department arrived, firefighters found the car upside down in the creek.
Three of the car's occupants were able to walk away from the crash, said Battalion Chief Neal Berryman.
The fourth had to be lifted from the creek with a Fire Department crane and was taken to an undisclosed hospital.
Maria Kelly, whose 16-year-old son was one of the teenagers in the car, said she called her son right after the accident. She said he told her that his friend had just "crashed his car."
Liz Ball, who was watching a baseball game across the street at San Luis Obispo High School, said she heard the screech of brakes, a loud bang and then three crashing noises.
When she got to the creek bank she saw three teens — two boys and a girl — crawling from an overturned car.
