There's a taxi course with online test... will test you on basic english, places of interest and road routes in singapore....
Better be quick if you want to take up taxi driver license as a backup... although the profession might be perceived as a lowly profession compared with the others.. but there is no other job that can immediately put instant cash in your hands when you need it the most....
Not too sure if the authorities will slowly open the flood gates for FT to also infiltrate this sector like for the bus drivers... the Retirees/Unemployed better pray hard hard.. pray that the taxi operators companies will not give into their greed.. and allow FT to come in and snatch the very last ricebowl( paperplate ) away...
