Driver training varies by province. Here in Shanghai, where I live, it can take months of lessons and several exams to get your license.

Actually there is a fleet of the EQ1 used for shared cars, I’m not sure which cities they are located in. Thanks to that fleet of rentals, there is a an auto insurance package here with added AAA benefits.

Most of the driving rules are the same as the US and the signs are quite similar in terms of their meaning. Street signs and highway signs are in Pinyin and Chinese characters. Only a few signs will be purely in Chinese, like parking rules, roadwork, or some driving limitations like the plate restrictions in Shanghai.
