The crash may be, but the fatality is down to the fact that US trucks aren't required to have side guards, which would have prevented the car from going under the truck.
It would require an awfully strong side guard structure to withstand the highway speed right angle impact of a heavy low slung automobile.

Even if the trailer substructure was able to prevent impact from submarining underneath, the sudden deceleration of the car from highway speed to stopped would be similar to head on collision or hitting fixed roadside structure given the weight difference between car and truck (I do not have any information regarding the actual weight of that particular trailer).

The fatality may have still occurred given the speed involved.
