Ah..... Did the laws change in IN?

So for those who run LTL line hail, I know you can run triples from basically the first toll after the skyway through OH. Tonight while driving on RT 2 about 5 miles west of 31 (west of South Bend) I saw an LTL carrier pulling triples. Did IN change the laws and allow triples on state highways or did this drive forget to leave his third pup at the drop lot.
(I know your allowed a certain distance from the toll road to drive to a terminal or drop lot, but this wasn't even close to the toll road, it's 15 miles.)

 

I'm not sure I want to call anyone out.
On the screen shot I added there is a road that runs down from Olive that crosses route 2. It was about that area. It wasn't RW/Yellow or old d or Conway or ups.

 

Many years ago, I actually saw a Conway truck with triples getting off on Thorndale from 290. I couldn't figure out how no one ever caught him. I believe he was headed to the Elgin terminal.
