National Car Rental typically applies a fee for adding an additional driver to a rental agreement. This fee may vary based on several factors, including the specific rental location and the terms of the rental agreement. It is important to note that some rentals may offer exemptions for certain drivers, such as spouses or domestic partners, who are added at no extra charge. Additionally, valid identification and a driver's license are usually required for all drivers listed on the rental agreement.
For the most current and applicable fees related to adding an additional driver, it is advisable to review the terms and conditions on the official National Car Rental website or to inquire at the rental location at the time of pick-up. Understanding these terms beforehand can help ensure a smooth rental experience and avoid unexpected charges.
