One of the fundamental principals of insurance is that you must have an interest in the item before it can be insured.
So the basic answer is no, if you do not own the car and have no interest in the car, then you cannot purchase insurance for it.
However, there are different interests you can have besides ownership like renting or borrowing. If you have a long term rental agreement you can get insurance or if you are borrowing someone elses car for a long time you can get insurance.
In either scenario you will have to coordinate your insurance coverage between the rental agency and the actual owner of the car.

If you don't own the car then typically you can't insure the vehicle, you don't have an insurable interest. If you are worried about having liability insurance when you drive other peoples vehicles then there is a type of policy you can purchase called a broad form policy. It provides you with liability coverage and doesn't cover a specific vehicle.
Understand that broad form insurance does not give you the option to purchase physical damage coverage such as comprehensive and collision. If you were at fault in an accident, repairs to the car would not be covered.
Car insurance needs to be obtained by the legal owner of the vehicle. You can not insure a car that you do not own. However, with the owners permission you can pay for the car insurance and be listed as a driver if you will be driving the car on a regular basis. Parents do this a lot for children who need help getting started on their own.
Yes, if you drive the car regularly then you want to get a Non-Owned auto policy. This is common for example if an elderly parent who does not drive owns the car but you use the car. Talk to a good local independent agent to find a competitive auto insurance plan that will meet your needs.
