Did you notice the truck in the video was overloaded way above the normal height of the bed? The truck could have easily passed any checks on paper, but the load itself is what causes the interference.
Yeah, in theory they would check the heights in the atlas versus the effective height of a given load, not just the height on paper. Why the truck was overloaded also begs a look at company policies. If this particular site is experiencing this issue 2 or 3 times a month then I wonder if the cost of guessing wrong and congesting the tunnel isn't high enough compared to just sending two trucks.
