01
Look for it in your own documents
Driving Other Cars, often shortened to DOC, is an extension that may appear on the policyholder’s certificate. It is not automatically included with comprehensive insurance. Named drivers usually cannot assume they receive the same extension.
Check the current certificate and policy wording. An old renewal email, comparison-site summary or what a friend’s policy includes will not answer the question.
02
Third-party only can leave a large gap
Many DOC extensions provide third-party cover only. If you cause a collision, the claim for the other vehicle may be covered while repairs to the car you borrowed are not. That is an uncomfortable conversation if the car belongs to a relative or friend and the repair bill is substantial.
03
Restrictions that catch people out
Some policies restrict the extension to emergencies or exclude cars owned by a spouse, partner or somebody at the same address. There may be limits involving vehicle type, occupation, age, where the car is registered and whether another policy already covers the vehicle.
The journey matters too. Social use does not necessarily include commuting, visiting clients or carrying goods for work.
04
A separate short-term policy
Temporary cover can insure a particular driver on a particular car for a defined period. That can be worth comparing when the owner does not want to alter an annual policy or when DOC would leave the borrowed car itself exposed. Check the excess, permitted use, territorial limits and eligibility before buying.
