Driving around the scales in ND, Mn, or SD is useless as they are very seldom open anyway and more are closing all every day. Troopers are carrying portable scales and are pulling truckers over all the time on the the highways. One of my buddies got pulled over 3 times in one day. Showing his previous ticket didn't mean squat either like the first trooper said that he should do should it happen that he got pulled over again.
