In the United States, are there any cultural norms or etiquettes that I should pay attention to?

The United States is a nation of immigrants, and it respects various customs and habits of different ethnic groups, without any particular taboos.

Since each state in the United States has its own laws, which may vary to some extent, independent travelers should be aware of the differences in traffic regulations across different regions.

American police officers patrol in cars, so even in areas with sparse traffic and pedestrians, it's important to follow traffic rules. Pedestrians who jaywalk may be fined $100 by the police.

American police officers are armed. If you need to communicate with the police, please follow their instructions as much as possible and avoid sudden movements, especially reaching into your inner jacket pocket abruptly, to prevent misunderstandings. If you hear "Freeze" or "Stop," it means you must stop immediately, so please comply. If you have communication difficulties, you can tell the police "I don't speak English," and they will try to find a solution.

Another thing to note is that smoking is not allowed in government buildings, most means of transportation, public places, and the vast majority of indoor areas. Many smoke-free hotels are equipped with detection devices.

Doing some research before traveling can make your trip more enjoyable. Wishing everyone a pleasant trip to the United States.
