As firefighters battled a fast-moving brush which was threatening homes in Corona, California, drivers on the 91 Freeway ran into huge plumes of smoke and flames along the side of the road.
Motorists captured dramatic videos of the flames as they raced up hillsides along the freeway.
The brush fire, officially named the Canyon Fire, was reported near the eastbound 91 at Coal Canyon Road, according to the Orange County Fire Authority.
Local residents have been evacuated from their homes.
