There are a fair number of farmers that run about in "TonkaToy" pick up trucks that are registered as farm implements that don't have to have an MOT but are limited as to how far they can travel in a radius of the *registered address.*
The same thing applies in that they are supposed to be kept in a condition for an MOT pass and obviously can be pulled up by the law.
This is all very well but most that I see look like they have done a few laps of a banger circuit with bald tyres and smashed lamps etc.
*By clever addressing ie JOE BLOGGS FARMS KENT PLC you can drive miles !
