oh for gods sake, what are you disputing here? the fact that when speaking to Bell and asking them to add DOC to my policy, and they changed the policy type to suit so i can drive any other car, which will result in the policy wording just like what has been posted above.
or are you disputing the bit i said about the other vehical requring it's own valid insurance certificate?
edit: if you actually read the OP, you'll see what the questions was weather or not the DOC option lets you drive other cars, or if you need to ring them up and tell them when you are driving other cars.
