Most Tanzanian roads do not have sealed surfaces, and travelling on them in wet seasons can be problematic. A law aimed at curbing accidents forbids public vehicles travelling between 10 pm and 5 am. Both short and long distance bus services are available. On the main long-haul routes, there is a choice between luxury and ordinary buses. Advance booking is recommended.
Taxis are available at international airports and in main towns.
They have no meters and tend to charge standard rates per journey for given distances. International driving licences are required of all foreign drivers. Vehicles must have adequate third-party insurance. Car hire services are limited and it is difficult to hire a self-drive vehicle. A light sweater may be useful in the evenings.
