The accident was reported at about 1:20 p.m. near the intersection of Walnut Avenue and Arnold Drive, according to the CHP.
The girl tried to make a U-turn but went too wide and crashed into the hospital, CHP Officer Jaret Paulson said.
She was not injured but was transported to an area hospital as a precaution because of her age, Paulson said.
The CHP is not releasing her name pending further investigation, Paulson said.
