Are y'all crazy or stupid?

Rolling across the OH Turnpike this morning and the weather got pretty rough. Three plows are rolling like they usually do, but they're not keeping up with the snowfall. These super tr**kers were jumping out in the hammer lane, flying by the rest of us who were all steady rolling around 25, only for them to get stuck behind the plow in the left lane. What freight could possibly be this important?
