It was a double load set up which are dangerous and sway non stop if you’re been stuck behind them on the road.
The Ca I-5 is very dangerous design and needs to be widening and a dividing wall .
I read this truck design causes heat to build in the back tires.
When on the highways, I stay well clear of the UPS and other dbl-trailer loads; just seeing that 2nd trailer ‘wagging’ even a little, scares the crap out of me.
In some western states other than Kalifornia, you’ll see Fed-X Triples running the roads.
