The FedEx truck was in flames before it crossed the center divider and collided with the bus. I think that it's pretty safe to say that the big fire was the truck's fuel, (diesel), until it ignited the bus's fuel, also diesel.

The irony of the OP is that there are huge safety problems in the motor coach industry, ( tour busses), that will only be solved with a lot more regulation and oversight. Not necessarily this particular bus operator, (they might have maintained their equipment to a "T"), but in general it's a scumbag industry with major safety and equipment violations being the norm. Horrendous crashes are very commonplace due to faulty brakes, overworked drivers, etc.

If it's left to that industry to police itself, most will run bald tires and unserviced brakes with some meth smoking monkey behind the wheel.

So yeah, excessive govt. regulation is clearly the problem.
