Stuart30 - To answer your original query - is it legal for me to drive this car?
You are quite correct, the DOC extension insures the driver, not the vehicle.
As said, you are not the vehicle owner and so you dont care if its insured or not (perhaps the Ins Co will, best check) so long as your backside is in the drivers seat.
As soon as you get out, its uninsured and the owner (not you) can and does get nicked for using a vehicle without insurance or security on a public road.
How did it get there? You drove it... Thus valid for you to be charged with causing or permitting the offence and thus just as liable as the owner for no insurance and reported accordingly...
As said, contact your insurer and in particular, the underwriters, as it is they who sign off the claim in case of an accident, not a lass in a call centre.
