You don't pick up trash in a tractor trailer, you transfer it to the dump.
What is the facility it was loaded from?
Where is the dump location it was headed to?
What is the normal route for, usually overweight and road bonded, transfer trailers to the hole?
And they sent idiots. They should have done a fire drill with the passenger, pulled the lock pin, and drove out from under the trailer leaving it sitting on the Trax to get lodged under the train engine in order to do mass dmg.
Idiots and traitors.
