There is no perfect solution, and there will always be some risk. Here are your best options if you elect to do business with Explore Rentals:
Purchase RCP insurance. This reduces exposure to $250 in the case of Collision. RCP Insurance does not provide any liability coverage.
Choose one of our less-valuable Roadwarrior or Super Roadwarrior class vehicles. These vehicles are closer to the value of the $20,000 max payout with RCP. The value of many of our standard class rental cars exceeds $60,000- leaving a big gap if something really bad happens.
Make the booking with a premium credit card that offers secondary coverage to auto rentals in the US. You will need to check your card coverage, but it is possible. This secondary coverage MAY cover the potential loss of use, towing, and other charges.
Purchase travel insurance that provides US rental car coverage. Secondary or tertiary insurance can help with the worst case scenario, and you will want health insurance coverage for the US anyway while you are traveling.
