A 1998 tan Chevy pickup collided with a parked silver Dodge pickup around 8 a.m. near First and Williams avenues in North Fair Oaks, according to the CHP.
The preliminary investigation suggests the driver of the Chevrolet lost control, drifting toward the right and running into the Dodge before overturning, the CHP said.
Officer Art Montiel said the driver, a 25-year-old woman, and a 17-year-old passenger were treated for lacerations to their arms. Along with the woman's 1-year-old, 5-year-old and 6-year-old children, everyone was transported to the hospital as a precaution, he said.
All four minors were believed to have been riding without seat belts or car seats. Charges may be filed against the woman for driving without a license, misdemeanor child endangerment and allowing minors to ride unrestrained, according to the CHP.
Witnesses to the collision may contact the CHP at 207-0315.
