You can search "montebello tanker truck fire" for other links.
For clarity, the incident happened east of downtown Los Angeles on what's called the 60 Freeway (sometimes called the Pomona Freeway) in Montebello, under the Paramount Blvd., overcrossing.
What's not clear is why the driver did not, or could not, move the truck off the roadway and onto the shoulder clear of the overpass, even if the brakes had locked up on the pull trailer, instead of abandoning it in a traffic lane.
