hello. bit of an odd question. me and a friend wish to swap cars for a few days in a few weeks, he wants to drive up country so he wants to swap his defender for my 308. his boss has fleet insurance with NFU. he is saying to me that anyone with a uk driving licence can drive any car on the fleet providing they have permission from the insurance owner. as neither cars are on the fleet he seems to think that they can still be driven on behalf of the farm insurance on a tempory basis without having to inform the nfu? is this correct?
