LA County firefighters worked to pull the person from the truck after it overturned shortly before 9:40 p.m.

The driver was freed around 10 p.m. and transferred to a hospital with mild to moderate injuries.

Emergency workers were told another vehicle was involved, causing the truck to overturn. It was believed one of the vehicles was traveling in the wrong direction.
