Sixt does allow additional drivers to be added to the rental agreement under certain conditions. Typically, additional drivers must meet the same age and driver's license requirements as the primary driver. This often includes having a valid driver's license and being at least a certain age, which may vary by location. When renting a vehicle, the primary driver can add additional drivers at the time of rental or during the rental period, though there may be an additional fee associated with adding more drivers.
It is important for all drivers to be present at the rental counter when picking up the vehicle, as their identification and driver's licenses will need to be verified. Additionally, any additional drivers must be named on the rental agreement to ensure they are covered by the insurance provided by Sixt.
For the most accurate information regarding specific policies, including any fees and requirements that may apply, checking Sixt's official website is always recommended. This can provide up-to-date details based on the rental location.
