At STEP2 of our 3 step online booking process, to the right of the car photo of your choice, is a link entitled "IMPORTANT INFORMATION". Click on this link and it will open an additional smaller window, where the terms and conditions appertaining to that particular car at your chosen location are displayed. Click on the tab DRIVER and search for "Additional Driver". Sometimes 1 driver is included, or the fee for an extra driver is mentioned at this section.
