Thanks Rob 
We don’t really need a whole lane but it would be better for safety’s sake,
It would be nice to open a cab door without it being ripped out of your hand as the next wagon passes,
As to following procedures, The police are always called if the truck it only just on the hard shoulder and can’t be moved, But it would be great to get a safety barrier of the nearside lane clear,
Also if the police are called they wan’t to know what you are doing, how long it will take, etc, and sometimes this can result in the police insisting that the vehicle be towed off! Which as you imagine this can be very costly. And it holds everyone up as when the blue lights are seen everybody slows to have a look, and this causes tailbacks!
Can any of you imagine how much water and spray is pushed under a truck on the hard shoulder when there are other trucks 3-4 feet away in the pouring rain.
I have great sympathy for the tow truck drivers that have to rely on motorists being aware of the situation, as when a tow truck is in front of a wagon coupling up, have you noticed that most of the warning lights on the truck can’t be seen very easily?
If just a handful of trucks move over then the car drivers might take notice and in time make the hard shoulder what it was ment for ,
