Thanks for posting the video.
Kentucky is very serious about the coal hauling, as you heard in the video, coal haulers can legally weigh 120,000 lbs. . That is only for coal, a regular freight hauler can only legally gross 80,000lbs. without a permit.
As a trucker, I can identify with everything stated in the video. I've hauled loads illegally that puckered my butt cheeks more than once. Hauled an oversized steel coil once.........couldn't cross the scale as I was weighing in at over 91,000lbs. , so I took the back roads. Didn't know until I was 1/4 mile from it that the bridge had a 30,000lbs. weight limit...........ain't turnin a 70 foot articulated vehicle around in a 1 lane dirt driveway. So I lined up with the bridge and stomped the throttle.
I've never hauled coal............my FIL told me enough stories that I stayed away from it.
