Taxis are plentiful, especially within urban areas like Panama City. All taxis are yellow and clearly marked. Most are small Japanese cars, although there are some trucks, especially in rural areas. The taxis in Panama do not have meters. The fares are either based on established prices for certain routes or on a series of zones established by law. The fares are usually pretty cheap (within Panama City, most rides cost around US$3) and tips are not expected. The fares are usually based on a single person, however, so group travel will cost more.
