SACRAMENTO (CBS13) – The California Highway Patrol is investigating whether alcohol was involved in an overnight crash on the freeway.

Four people were taken to the hospital when the car they were in flipped on Business 80 in Sacramento.

A 16-year-old girl was behind the wheel when, CHP says, she got off Business 80 at El Camino going too fast. She lost control of the car, causing it to roll.

All four of the people inside the car suffered moderate injuries and were taken to the hospital with moderate injuries.

Investigators are looking into whether or not alcohol was a factor.
