I often drive a friend's car. What companies offer "Non-car owner" auto insurance?

Everywhere i look online just offer "get a quote" then you have to enter a type of car. I don't own a car but I need insurance to take my driver's test in North Carolina. I couldn't find this type of insurance offered on any websites.

You are looking for a nonowner policy. This however, will NOT cover you for a vehicle you drive on a regular basis (your friend's vehicle you drive "often"). Insurance follows vehicles, not drivers so any vehicle that is insured (& the ID card & registration are in the glove compartment) will be fine to take the driving test with. If you are taking it in your friend's car, be sure he or she is with you when you go. If you will be a regular driver of the car (Progressive says if you drive it more than 12 times per year), you will need to be added as a driver to that policy, even if you are not in the same household.
