You can add drivers to your rental contract by showing their driving licences. If the additional driver is not present during pick-up, you can go to any SIXT branch to add them to the rental contract. Alternatively you can show their original driving licence document at pick-up.
If all of this is not possible, the leassee is solely responsible for the additional driver to be authorised to drive the vehicle. The rental contract does not need to be amended in this case. This scenario is only applicable if the additional driver is also an employee of the leassee’s company.
SIXT recommends entering the additional driver in the rental agreement to comply with all regulations in case of damage or traffic fines.
Please refer to your negotitated rate sheet or your Travel Management to find out whether a fee for additional drivers is applicable.
