In the USA, symbols, shapes and colours are used to communicate with drivers. They don't use any words. Learn these symbols for your safety. Traffic is common in America, so you should travel slowly in the right lane, which is better for you. If you are travelling on a highway, prferably use the right lane; otherwise, you will be crossing another vehicle. You should carry your valid driver's license and also IDP required for driving on roads or else you need to use public transport. You should be travelling in the right lane unless you cross a vehicle. Avoid honking unless there is an emergency. For example, if you are driving and someone is about to hit you accidentally, you can use a horn. If two vehicles intersect, then the car from the right lane should go first unless that vehicle is at the red signal. The speed limit is 25 to 30 miles per hour in many areas and residential areas, which is 35 miles per hour. On highways, the speed limit will be 55 miles per hour or more.

Before using any rental car, check whether you can drive with your non-US state driving license. You need an international driver's license before entering the U.S. because no other U.S. government agencies will issue an IDP. An international driver's license has all the information from your original driver's license in 10 different languages.

Generally, some companies hold a certain amount of money for accident insurance, so it is better to have an accident cover for yourself. You can also use third party insurance to cover your accident. If you have full coverage from rental insurance, then you can decline cover from rental companies. You must need a proper driving license to apply for rental cars. Many rental companies expect the license to be in English. If not, you need an international driving permit IDP for better understanding.
