So all of those yellow Penske rentals rolling up and down the highway that are under 10,001 lbs are Not CMV and do not need to scale....
True!
Don't worry about the Kettles; once they show the officer their rental contract and open the roll-up high enough for him to see furniture and grocery boxes marked "Billy's Room", they'll be thanked for their cooperation and told to have a nice day.
On the other hand, the guy who acts nervous and shifty in the presence of authority, who doesn't want Officer Krupke to see the 8 pallets of dollar-a-mile freight in the back of Ole Yeller, HE has a right to be nervous now
