Hi. Just trying to clear your doubt, hope it will benefit
you.
1. You can put your original insurance in your car or just a
photocopy one will do, the purpose is just to let the police to
verify in case of road block or kana caught for "xxx".
2. The insurance will appear the registered owner name and you can
add a additional driver in. All others unnamed drivers can still
drive your car as long as they had the owner permission, The only
difference is that in case of accidents and you need to do a self-
claim, the unnamed drivers will pay a higher excess than the named
driver. eg. Named driver : $500 and unnamed driver : $1500.
Hope it clear your queries...
