How would NJ have any jurisdiction should he choose to sell it to someone in a free state (that permits off-road use in current condition)?
I am not really sure, I am sure he could fire sale it to someone with a trailer in another state, the state couldn’t do much about it
But he would have to do it quickly or face something like a 15K a day fine
Diesel vehicles are considered commercial and follow a strict guideline in the state
This is all wrong, but they probably claim current jurisdiction and short of the $10k repair, will start to assess fines against him as there is no other legal way in their view to reolve this unless he destroys it. Even of he tows it to another state along with himself and all of his possessions, they will still go after him for all of the overdue fines and hound him for the rest of his life. Be a shame if due to publicity of this, the truck gets stolen and is never seen in NJ again.
NJ would have contacted the FBI to kill him.
Or sell it to a person in a state that doesn’t require emissions testing for on-road use.
