You can get insured for short terms whilst being on a provisional driving licence with
Collingwood Learner Driver Insurance. With this type of learner insurance you will be able to drive your parents' car or any family/friends' car when you are learning to drive. Just so that you know, you will have the insurance policy in your own name which means that if you have any accidents (I hope you do not though!), the claim will only affect your policy and not the owner's no claims bonus.
