If using DEF from truck stops I'd think it would be safe as there are hundreds of trucks daily using it & would surely hear of lawsuits out the kazoo if selling bad DEF to truckers. I'd also suspect it's tested periodically just as the fuel & the pumps are by licsensed third party technicians.

This was at a pilot truck stop in NC, I guess this is how they bring in the def fluid? I don’t think it would be windshield washer fluid... I used the def at the pilot because I think your right... a lot of truckers use it
