off of Fox40.com Out in California:
A truck pulling a trailer of cars caught fire Thursday afternoon, closing a section of southbound Highway 99 in Keyes.
The driver of the truck reportedly saw smoke coming from the back of the trailer. He pulled over and grabbed a fire extinguisher but by the time he got to the fire, it had already spread.
That section of southbound Highway 99 was closed for just over an hour, and opened up again shortly after 2 p.m.
