A yellow roof on a vehicle indicates a metered taxi. Cars are usually black and yellow. They are easy to find in cities, and can be hailed by standing on the street corner and waving your hand. Most cabs are metered, but make sure they start at zero when you start your journey. Cab drivers may charge extra for luggage. Radio taxis (remises) come without meters for a fixed fare to certain destinations. Ask about the fee before embarking.
Cars (and motorcycles) can be rented for reasonable rates in major cities. Petrol will prove expensive and insurance is mandatory. Because of the potential for crime against lost tourists, rentals should only be made by experienced visitors or when accompanied by a guide. Cars with drivers can also be rented for daily and weekly rates.

There are more than 21,000 miles (35,000 km) of rail in Argentina, making it one of the most extensive in the world. However, many of those rails are not in service. Train service in the greater Buenos Aires region, however, still exists, and often at less expensive rates than the bus. Inter-city routes are not advisable for business travel as the schedules are not dependable.

The subterranean system in Buenos Aires, comprised of five lines and known as subte, runs until 1:30a.m., except Sundays, when it stops earlier. If planning to use the subway more than once, buy several tokens in advance to avoid the lines during commute hours. Maintain a high security awareness when riding the subway, especially at night.

Buses (colectivo) run 24 hours a day in Buenos Aires, but are often crowded. Expect as reckless a ride as you might in any other mode of motorized transport. Fares vary according to distance. The main bus station (Estaci?n Terminal de Omnibus) is located at Ramos Mej?a 186 in Retiro. You can call 4315-3405 or visit the second-floor office for information. Smaller towns have their own systems and an extensive intercity system exists that is reliable but not terribly comfortable.

There are a few river ferry services for travel to more remote towns, but these should be used only as a last resort. Private boats can be hired at daily and weekly rates. Buenos Aires has an efficient hydrofoil port at Darsena Norte that serves the Uruguayan cities of Montevideo and Colonia.
