You will need a valid driver’s license, plus an ID or passport for a SIXT car rental in Romania. Travelers from outside the EU will also need an international driving permit.
One-way rentals are allowed between SIXT locations in Romania, depending on the tariff and car category.
The minimum age for a SIXT rental in Romania is 18, with a driver’s license held for 1 year. Some car categories have a higher minimum age, and an underage driver fee applies to those under 25.
