The topographical assessment tests someone's ability to map read, to plan a route in the context of a pre-booked journey and their general geographical awareness and directional understanding.

Transport for London (TfL) allows two attempts to pass the topographical assessment per private hire driver application. The assessment currently consists of five modules and takes two hours to complete; the required pass mark is 60 per cent.

TfL is currently producing additional modules that will test private hire driver applicants on a range of other items including their understanding of relevant legislation. Once introduced, it is envisaged that the test will take approximately four hours to complete.

TfL recommends that those taking the test prepare for the assessment in advance.
