NJ used to be rather hard to even pass when your car was in good shape. today all they give a crap about is that the cel is off and you have a cat.
light duty commercial trucks like pick ups and any thing under 24,000 gvw they check everything. i mean everything.
best part is inspection is free and good for 2 years at the state locations, or you can pay at a shop, but thats dumb aint it?
