Local laws and etiquette

Always keep your passport and driver’s license with you when driving in the US in case you are stopped by the police.

You can turn right at a red light (provided you come to a stop first and there is no oncoming traffic and no contradicting sign saying “No red curve”).

Most American cities require you to park your car on the correct side of the street in the direction of traffic. Otherwise, you will be put on a ticket and fined.
