Leo ni siku ya taa za barabarani ambayo taa ya barabarani ya kwanza iliwekwa tarehe 5 August 1914 huko cleveland ohio USA, system ilitengenezwa na bwana Lester Wire na leo ndo inatimiza mia tangu zianzishwe. Traffic lights za kwanza zilikuwa na rangi mbili tu mpaka mwaka 1923 ilipoongezwa rangi ya njano. Je ulilijua hili? Your favourite presenter. Selemani Sele
