Except that such an interlock would under normal circumstances be
counterproductive on such vehicles. What was needed was for the driver
to look where the hell he was going.

As I pointed out in another post, there are occasions when tippers
need to be moved with the body in the up position.

Though I agree that is a fair point.

Which negates your arguement about interlocking.

No, because if the driver had the ability to override the interlock (at
very low speed only, say) it would be possible to achieve the desired
effect.


Speed wasn't the problem here, the idiot driver wasn't paying attention.

Going back to your signalling metaphor, I believe there has been at least one
accident caused by the signalman deliberately overriding the interlocks.
Plus one, Hull Paragon, where the interlocking was accidentally defeated.
