Louage are minibus share taxis in Tunisia. In French, the name means "rental." Departing only when filled with passengers not at specific times, they can be hired at stations. Louage ply set routes, and fares are set by the government.
In contrast to other share taxis in Africa, louage are sparsely decorated. These white vans sport a single colored stripe that alerts potential passengers to the type of transport they offer. Red-striped vans travel between major cities while those with yellow stripes ply routes with more bucolic stops. Blue-striped louage can also be seen. Small placards atop the vans specify either a van's exact destination or the town in which it is registered. In 2014, a one and a half hour trip cost about US$2, and an intra-city journey, approximately US$1.
At some louage stations, tickets can be purchased at a booth and given to the driver, although c. 2011 this practice was rarely followed.
Prior to the introduction of vans, French-made station wagons were used as louage.
