He just runs right over old farm tractor

Well, that's not an interstate. Farmers use the two lane roads to get to their fields, don't know how else they'd be able to access them if they didn't.

Very tragic for the man on the tractor.

He was completely legal too with his slow vehicle sign. Hoping somehow he came out ok.

He was on a divided highway going, at best, 25mph. Trucker was in the wrong, but tractor man is the one that lost.

Just because it's legal doesn't make it wise.
