If he was caught "off guard" he is incompetent or careless IMO. One of
his duties is to know exactly the clearance height of his vehicle.

Another solution for fixed height vehicles would be to mandate the
fitting of warning devices to the vehicles themsleves; I saw a very
effective radar system in use on a coach some years ago. However, this
would be harder to put into practise for vehicles like this one that can
carry a variable height load.
