Basil Jet remarked:
surely the point of these crashes is that the bloke thinks that even
though the sign/detector/water curtain thinks that he's too high for the
bridge/tunnel, he thinks that he'll squeeze through with half an inch to
spare, and a lot of the time he'll be right.

It's much more likely they just forget what they are driving (how high
etc).
Exactly. The various "hanging is too good for 'em" pundits here need to
consider that the driver is dealing with a combination of the deck height of
the trailer, the height of the container, and quite possibility the tractor
unit may affect the height as well. Nobody is questioning the fact that the
lorry driver is responsible for making sure it will all fit, but given the
opportunities for mistakes to happen it's a wonder there aren't more
incidents of this nature. For example, it's possible that the driver passed
under the same bridge with a smaller container in one direction, and then
swapped it for a taller container - or even a taller trailer/container
combination - for the return journey.

What happened is comparable with a signaller setting the wrong route for a
train and then the driver accepting that route. Surely that *never* happens,
does it?

There but for the Grace of God, etc. etc.
