No. The rental car company requires a valid license. The insurer requires a contract with a rental car company. I suppose the assumption on their part is that the rental car company won't rent to you unless you have a license? I have recent experience in this regard.... a few years back in France I crashed a rental car and was slugged the $4000 excess. When I made the claim back in Australia the insurance company just asked for the rental agreement and the "proof" that I was charged the excess, which in this case was a credit card statement. They didn't ask me to provide my license to them. And I didn't have an IDP eitherSo nothing about requiring a valid driving licence?
