Taxis (also called cabs) are cars with a company name and number on the side and a light on the roof. In big cities like New York you can stop one on the street. In most other places you find them at airports, train stations and big hotels, or you call or book in the taxi company's app.
Taxi stand: a marked line at airports, stations and hotels. Wait your turn.
Hailing: in big city centers, stand at the side of the street and raise your arm. A taxi is free when its roof light is on.
Phone or app: search "taxi" plus your city in a maps app and call the company. Tell them your address and when you need the car.
Most taxis use a meter: a small screen that adds up the price by distance and time. Check that the driver turns it on when you start.
Some trips have a flat rate: a fixed price, for example between an airport and the city center. It is usually posted at the taxi stand.
Extra charges can be added for tolls, bags, late night or the airport.
Most taxis take credit cards on a screen in the back seat. Some take only cash. Ask before you get in: "Do you take cards?"
Tipping the driver is normal. Many people tip 15 to 20 percent. The card screen often offers buttons for the tip.
Use only licensed taxis. A licensed taxi shows a license number and often the driver's ID inside.
Do not accept rides from people who approach you inside an airport or station.
Take a photo of the taxi number if you are alone at night, and send it to a friend.
Ask for a receipt. It has the taxi number, which helps if you forget something in the car.
Apps like Uber and Lyft show the price before you go and keep a record of your trip. Taxis are useful when your phone has no data, at a taxi stand with no line, or where taxis have special lanes at the airport. Both are fine; compare the price.
