Road signs in Tanzania are based on the SADC Road Traffic Signs Manual, [1] [2] [3] a document designed to harmonise traffic signs in member states of the Southern Africa Development Community. They are regulated in A Guide to Traffic Signing governed by the Ministry of Infrastructure Development. [4] Tanzanians drive on the left.
