Tunisia has a large road network connecting all of the main cities and towns. Even small cities have some form of public transportation. The main motorways in Tunisia are well maintained. The road signs are in French and Arabic.
When in Tunisia, you can hire a car, taxi, or travel by coach. International and local rent-a-car companies can be found at every airport or major cities. You will have to be 21 years old to rent a car.
Taxis in Tunisia are private metered and long-distance (shared) taxis are called, louages. If you are in the city, private metered taxis can be a good option as they are reasonably priced. For a half- or full day tour you should negotiate a price in advance rather than going by the meter. The long-distance taxis (louages) have departure points and serve the whole of Tunisia. The only downside might be that for the taxi to start it has to be full which can take some time. Otherwise, this is considered the fastest means of transportation.
The national bus company SNTRI runs a fleet of air-conditioned coaches between towns and across the country. Booking in advance is recommended.
