Perhaps it would be useful to educate some of the idiots who steam up behind a truck at 75-80mph without realising that the truck is only capable of a maximum of 56mph.
As for those who think that they’ve see bald tyres on a truck that’s still in motion, I doubt it. If a tyre blows it’s bound to put more pressure on the remaining ones, think about it. Anyway, trucks are subject to a safety inspection every 6 weeks. When was the last time you paid for a thorough mechanical inspection of your car ?
Rather than closing lay-bys, why not provide MORE adequate stopping and ovenight parking for trucks in the area?
