If you take out third party or third party, fire and theft insurance you will usually only be covered to drive your own vehicle. Some fully comprehensive car insurance policies, on the other hand, also provide the main driver on that policy with third party cover to driver someone else’s car. This type of ‘any car’ inclusion used to be very common on fully-comp policies, but some insurance providers no longer include it as standard so it’s essential that you check the wording in your own policy documents before getting behind the wheel of a friend’s or family member’s car. If an ‘any car’ inclusion isn’t included on a fully-comp policy as standard it may be possible to add it for an additional fee.
