I’m far from the brightest guy in the world, but even I know what a “Caution: Low Clearance” sign indicates.

My assumption would be that truck drivers have this knowledge as well.

Such isn’t the case, as evidenced by a video I came across while doing some research online. The video focuses on an underpass that flattens the tops of a number of trucks as they barrel through.

Could it be that the drivers are distracted and don’t see the low clearance signs? Do they not understand what such signs indicate?

Perhaps they don’t believe that all signage is correct?

This is one of those things that will have you shaking your head in amazement.
