See we have had this said before ( few months ago on this bored) now as my F car insurance is up in 3 weeks i just rang them to see the price of the renewal

As i can drive any other car on my insurance etc etc.. not belonging to me etc etc.. I asked NO the other cars that i MAY need to drive for whatever reason DOES NOT need to be insured.

Only thing which would cause a problem is parking it upon a public road etc and walking away, then the owner of that car could be done for having it on the the road with no insurance..

People need to check their own insurance to be sure but assuming that the other vehicles need insurance is not always correct
