Most important driving rules while driving in the USA

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. For drivers 21 years or older, driving with a blood alcohol concentration (BAC) of 0.08% or higher is illegal. 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.

Mostly in the U.S., many rental cars are not insured, so make sure you take an insured rental car. You can also purchase insurance products like personal car insurance, travel insurance, credit card insurance, etc. School buses with flashing lights are an important signal that shows that you must stop the vehicle. In the U.S., the legal age of driving is a little different from state to state; it is between 16 and 18. But for a foreigner, you need to be at least 21 to get a car for rent. It's not a rule, but many rental companies follow it.
