No one was injured in a big rig tanker crash Wednesday on the 5 Freeway that closed up to two lanes, sent a truck up onto a Mini Cooper and caused a fuel and oil spill, authorities said.

The crash, which involved three vehicles, occurred shortly before noon when the Arco fuel tanker collided with another big rig truck near the Western Avenue off-ramp, officials said.

Incredibly, no injuries were reported.

The tanker overturned at about 11:56 a.m., spilling about 25 gallons of waste oil and diesel fuel on the dirt shoulder, according to the CHP. The other big rig truck in the initial crash ended up resting atop a Mini Cooper.

Waste oil, some of which spilled on the roadway, first had to be offloaded from the tanker before it could be moved and lifted upright.

A Sigalert was issued until 7 p.m. for the lane closures as crews worked to clear the debris and oil from the road way, snarling the local freeway commute.
