A motorcyclist had to drop and roll to extinguish the flames after a fiery collision Wednesday along Interstate 5 in San Diego.
A mattress in the southbound lanes of I-5 near Clairemont Boulevard caused the motorcyclist to collide with another car just before 10 p.m.
California Highway Patrol officers said the motorcyclist caught fire in the crash and rolled around in the lanes to put out the flames.
Several lanes were closed in the area.
The motorcyclist was taken to UCSD medical center with burn injuries.
