The one constant I've encountered every time I've rented a car is that I needed to present a valid driver license. As an example, I looked up Dollar's policies.

C. Authorized Drivers: The DOLLAR vehicle may be driven only by an authorized driver. An authorized driver is the renter and any additional person who appears at the time of rental and signs the rental agreement. All authorized drivers must satisfy our age requirements, have a valid driver’s license, provide a physical street resident address, a major credit card in their own name, and fulfill our other qualifications, which vary by location. Employers and co-employees of renters renting on corporate rate plans, if properly licensed and meet our age requirements, are authorized to drive the vehicle while acting within the scope of their employment duties. See our credit requirements and driver’s license requirements below.
The authorized driver and any additional authorized drivers may be subject to a driver record check (See below). No other persons are authorized to drive the vehicle.
L. Driver's Licenses:
United States Citizens and U.S. Military Personnel: A renter or any additional authorized driver who is a citizen of the United States, must present at the time of rental:
(1) a driver’s license issued by any state, territory or possession of the United States , and valid for the entire rental period.
(2) a temporary driver’s license, valid for the entire rental period
(3) a traffic citation issued as a temporary license, valid for the entire rental period (the court date being the expiration date) and a second form of identification with signature (excluding the credit card used for rental)
(4) a valid U.S. military identification card plus an expired driver's license for active duty U.S. military personnel in those states where active duty U.S. military can drive on an expired driver's license
(5) a valid driver’s license issued by a providence or territory of Canada
(6 a foreign driver’s license* issued by the country of residence of the renter and additional drivers. If the driver’s license is not in English the renter and drivers may provide a current International Driver’s Permit (“IDP”); or, if from Japan, a Japanese Translation Service. An IDP does not give a person the right to drive, but provides a certified translation of the valid foreign driver’s license. An IDP (or certified translation) without the foreign issued driver’s license is not acceptable.
*If the foreign issued driver’s license is from a country where “permanent” or “non-expiring” driver’s license are issued, the renter and any additional drivers will also be required to show their passport, visa, or other current U.S. issued documentation at the beginning of their rental authorizing the renter or driver to be present in the USA at the time of rental.
