Head over heals

Counter intuitive road signs.  The one referring to the matters low down is up high and the one referring to high up is low down.  So the height restriction ahead warning is below the speed hump warning.   That's counter intuitive at best and simply illogical.

Maybe there's a prioritisation in the order, firstly the speed restriction to slow down to 15mph, then the speed bumps sign to reinforce that, and the height restriction would apply to fewer vehicles anyway.

Trying to communicate with someone driving a ton or two of steel, this seems like extra unnecessary effort to fathom, it just feels wrong.  The irony of this is of course that these safety measures are designed are to reduce risk.  Hopefully the signs this way do not detract sufficiently from that.
