One-way rentals between SIXT locations are generally allowed. Additional fees may apply.
You will need a valid driver’s license to rent with SIXT, plus a passport if your license is not from the US. International renters with licenses that use a non-Roman alphabet like Cyrillic or Arabic will also need an international driving permit.
The minimum age for a SIXT rental in the US is 21. Some specialty and larger car types require drivers to be 25 or older.
