The origins of the name Tro-Tro is that Ga language word "tro," which means three pence (pence being the penny coins used during Ghana's colonial days). In the colonial days, the mass transit vehicle charged passengers three pence per trip, and thus were referred to as "tro-tros," and the name have struck ever since.
A tro tro is a general term for any public transportation vehicle other than a bus or taxi that is designed to carry many people. .... Visit the Trotro Page
