You may already have it with your credit card. Check with customer service and ask if that benefit is included with your card. If your credit card does not offer it, you can usually purchase extra coverage from the rental agency.
Just be prepared for a high cost. If your regular car insurance doesn’t cover it, or if you do not own a vehicle with insurance, you will be required to purchase extra coverage before being allowed to drive a rental.
