Do I have to pass any tests before I can get a taxi licence?
If you want to drive a black cab (London-style Hackney cab) you have to sit and pass a knowledge test of the area in which you wish to operate, so that you have an excellent knowledge of local streets and roads. There is also a non-obligatory test that ensures you know how to help disabled passengers get into and out of your cab. If you want to be a private hire taxi driver, you are not required to sit any tests.
