All a bit drastic.
Fifty mile radius of where/what ?.
HGVs roam the whole country from their base.
I get the impression that the penalties/costs for hitting a bridge are already stiff enough.
So what is the problem that lets this still happen ?.
Is is not necessarily sloppy driving so punishment is a rather pointless exercise.
If punishment is going to do anything then it is going to reduce the number of HGV drivers of which there is already a shortage.
I am not pro HGV and wish we still had the lower axle weight but I am convinced preventing bridge bashes is not straightforward. As
@Bald Rick says - the penalties are already there. We need to look at how this kind of mistake comes about.
I feel it is likely that humans do not generally consider headroom as I have alluded to before. If that is a deeply ingrained feature of the human brain then we have to accept that weakness and find ways round it.
AI in the cab ? - maybe one day.
Reduce the number of low bridges ? - raise where practicable the worst victims.
BUT for drivers who can be proven to be trying it on by slowing on approach and then squeezing through even if no damage then perhaps we should be using a stick there.
