Yes, you can usually add one or more additional drivers, depending on the supplier. You’ll often be charged an additional fee for each one. When the additional driver is free of charge, it will be stated in the section of the Rental Conditions.
An additional driver must be with the main driver when picking up the car in order to sign the rental agreement. All requirements that apply to the main driver also apply to an additional driver.
You can add an additional driver when booking your rental car or at the rental desk — there’s no need to book one in advance.
