It happened around 4:45 a.m. in the southbound lanes of the Roosevelt Boulevard Extension between 9th Street, going on to I-76 in the East Falls neighborhood of Philadelphia.
A driver had to be extricated from one of the vehicles.
The truck, meanwhile, veered off the road, ripped off the guardrail along a 40-yard stretch, and came to a rest teetering on the median into the northbound lanes, while leaking fuel onto the roadway.
The jaws of life were also used to free the truck driver.
