Cleanup of 5th wheel accident in California

That stretch of road which I see everyday with my work has had many issues. I am sure to be driving from LA area to get to Glamis at that hour of the morning that the guy has driven that stretch before and possibly tired. Morning sun had to be in his eyes and he never saw the yellow until to late, or wanted to beat the light because of the traffic of trucks ahead. That road is busy in the morning on a normal day let alone a holiday lets go to the sand dune weekend and party.
