   1. Conditions for Chinese citizens to drive in the United States for a short time
For Chinese citizens to drive in the United States for a short time, they must first have a legitimate Chinese driver’s license, and secondly, they need the driver's own English notarial certificate for the driver’s license of the government’s notary office in China. In particular, if you encounter a traffic police check in the United States, you do not have a notary certificate. In addition, the other does not require any special conditions.
There are many people who say that they can get a car by directly taking a Chinese driver's license. This is because the new Chinese driver’s license is translated in English. However, this is not absolute, because the English translation of the driver's license above is incomplete. You may encounter problems when you mention the car. The company may refuse to recognize your English driver's license. At this time, your driver's license in English translation will work. Therefore, it is recommended that you go to the notary office before you go abroad to get a copy of your English driver's license in case you need it. You can use it more than once after the notarization, until your license expires.
2, insurance issues
   As for insurance, in California, third-party liability insurance is mandatory, and some states are not. We recommend purchasing purchaseability and LossDamageWaiver (LDW). Although the insurance premium is almost the same as the rental car's basic fee, if you buy the two insurance, in the unlikely event that there will be any accident, you will not lose too much. Don't be unhappy with this accident if you have such an accident. As for protecting your own personal accident insurance, it depends on whether your travel insurance or weekday commercial insurance is included, and then decide whether it is necessary to spend the money.
3. What are the United States car rental companies?
   There are a lot of American car rental companies. For example, the large international company Hertz, Avis; medium-sized Alamo, National, Budget; online popular Thrifty, Dollar. You can choose the right company based on your needs. Among them, Hertz has the strongest strength, with outlets in more than 150 countries including the United States, Europe and Australia, and more than 7,800 car rental service points.
If you are renting a car in the United States for the first time, and if you are in trouble, it is still recommended to choose Hertz. Although relatively expensive, the condition and service are still good. You can book through an agency such as Expedia, hotwire, AAA, or directly on the American Car Rental Company website. It is also more popular to use Priceline to make affordable car rental. However, although Priceline can control the price, it cannot choose the car rental company.
   4, the choice of models
   The choice of models is generally that of Ford and Chrysler. There are also many modern cars in the economy. Economy, Compact, Mid-, Full-, Wagon, Van, and so on, different car classification prices and suitable number of riders are also different. In general, Mid- is the most mainstream model. Sometimes we have to rent a low-grade car and upgrade it to a premium car for free. In general, Mid-enough to use. As for cross-country, it depends on whether your travel route is necessary or not. It is not necessary to take a trip in the national park. Although the convertible pulled the wind, but the fuel consumption is indeed too exaggerated .
