I do not understand how a hire company can hire a 7.5 ton vehicle out to someone who does not have an Operators Licence,I had to study road transport operation and pass a City and Guilds before I could operate trucks in UK,Europe or Eastern Block.I had an O licence for 100 trucks,2 of which were 7.5 tonners and all had O licence discs in the windscreen(blue for uk domestic use,green for out of UK),also if a truck is fitted with a tacho it is there to be used ,after it is a commercial vehicule designed to carry a load,also drivers hours need to be kept to.
