Class A Fire

Several moths ago we came upon a semi on fire on I24. There was nothing left except the left front tire and wheel. A very hot fire in the right rear corner of what had been the trailer box. THP had people passing it in the left lane. The semi was on the shoulder. It was so hot wife, who was driving thought it burned the hair. If we had set there for a few moments it would have scorched the paint and us. No engine was evident and nothing but some frame work of the box was evident and it was on the ground. No rear wheels axles, no evidence of body or sides of box. I think there was a bit of the front bumper. On tremendously hot fire to consume wheels tires axles, evidently the engine, entire body minus some framework, glass, everything. Several days later we drove by and nothing but burned pavement the size and shape of the entire semi.
