Here's one for ya... First let me say I Was Not There to see it, but I pretty much trust the guy who told me..(another Joplin driver) . Yesterday a Joplin MO driver was held at the scales 3 hours because of,,, a flat tire, no tail lights, improper placards,,, and carrying URANIUM.. Not sure but IF it was the Joplin scales, they have a framework you drive through with multiple camera's, heat sensors, AND radiation detectors... This driver is the same one that a couple months ago after Joplin lost a road driver (killed) in a motorcycle wreck , said in front of several drivers he wished a couple more would die so he could move up some more... That part I know is a fact.... Carma ???? Check your stuff drivers.... Last thing I do before crossing the scales is look in the mirrors to make sure the side and top trailer lights are on ...... If they are,, chances are "pretty good" you have tail lights...
