The answer will depend on your insurance coverage. If you do not have insurance you will likely be responsible for the cost of the vehicle. If you do have insurance with comprehensive and collision coverage, check with your insurance company.
This is another way to describe rental reimbursement coverage. Meaning, if your vehicle would temporarily disabled due to a covered claim/incident, this coverage would reimburse you for the transportation expenses you have.
As you do not own the vehicle, your only other option is a non-owners policy which can be purchased some insurance companies. However, most insurance companies don't sell temporary insurance - regardless if its owned or non-owners.
