Of course, if councils do in-house testing then the likes of the above likely to be less relevant to 'monitoring diligence', I'd guess.
But that kind of thing, together with the stuff about daily walkround inspections, is probably consistent with the kind of remote Wolverhampton approach to licensing and inspections. So rather than directly inspecting vehicles, the onus is more on drivers and proprietors, and a less direct approach to inspections by using the MoT system instead, and requiring reports from affiliated MoT garages, and/or doing it remotely via the MoT database
Of course, unless there's some sort of affiliation between the council and an MoT garage, they're not going to be able to request written reports.
So presumably Wolverhampton will be checking 30,000 cars via the MoT database?
They've not other way of 'monitoring diligence' if they're not directly inspecting cars in any way
