美国乔治亚州自驾问题？中国驾照加公证件现在

刚看乔治亚州DMV网站上说：Non-US citizens holding a valid foreign driver’s license are allowed to drive in the state of Georgia for tourism or business purposes. If the foreign license is not printed in English, the driver must also have an International Driving Permit (IDP) or similar translation issued in accordance with the provision of the Convention on Road Traffic, any similar treaty, international agreement, or reciprocal agreement between the United States and a foreign nation.这个similar translation issued in accordance with the provision of the Convention on Road Traffic, any similar treaty, international agreement，到底是什么东东呢？？
今年十月想去美东，中国驾照真是个大问题……
