Crikey, that's bad.
Yes, from the photo it looks like it skidded.
A private operator apparently, so not Veolia.
No information as to whether anybody was hurt, but unless there are mitigating circumstances (eg the driver suffered a sudden health incident or the brakes failed, though it shouldn't have been going fast enough to need the brakes at that point, surely) it looks like a prosecution for a driving offence is likely?
Do vehicles like this have some kind of technology which retains the speed history etc?
