Dass,
That's not necessarily true. For third party only and third party, fire and theft policies, you are not insured to drive another car except the one on which cover is provided. Most comprehensive policies however, allow you to drive any other car on third party coverage only. Note that I said most comprehensive policies and not ALL. You will have to check your policy documents to be sure whether you are allowed to drive another car or not. If that's included in your policy, then you have to understand that in the event of an accident, only the third party will be covered under the policy. Any damage to the other car (the one you borrowed) which you have been driving will be at your own expense.
