Come on, give the company (the big bad nasty man who pays your wages) a break.
A wheel that comes of in 60 mile has been already loose. (For a while)
The driver has done his walk around check (and no more than that, walked around) but clearly doesn’t have a clue how to inspect wheelnuts and how to see the marks that indicates a loose nut.
Those plastic wheelnuts markers, don’t even mention, drivers rely to much on them, the ones who cover the whole nut are evil (have seen a complete loose nut under them.)
The other ones, have came across “drivers” who put them “right” when out position.
What is wrong with the drivers nowadays■■?
For 50 odd years we had never markers (and you will see them very rare on trucks from the continent) we used visual and acoustic.
I always tap them (and the tyres for pressure) and every time I leave the truck, walk away on the O/S and give them a glance and walk back on the N/S and give them a glance on that side.
Look for wear around the nut, rust marks, it’s so easy.
So yes a driver which loose wheelnuts should loose his license, and if somebody got injured the courts take a very dim view on this, as it is driver RESPONSIBILITY!
