Hackney Carriage and Private Hire knowledge test


As part of an application for a Private Hire/Hackney Carriage Driver’s Licence or a Private Hire Operator Licence candidates are required to pass a written knowledge test. 

PLEASE NOTE: This test can only be booked once a valid application has been submitted to the Licensing Department.

The driver licence test will consist out of 30 multiple choice questions. There will be 4 sections in this test:

  • section 1 will be 15 questions based on the Hackney Carriage and Private Hire Policy (pdf) and the laws relating to PH and HC licensing - the pass mark for this section will be 100%. This means that an applicant must answer ALL questions in this section correctly - if any question is incorrect then this will be an automatic failure of the entire test
  • section 2 will be 5 questions based on numeracy  -  the pass mark for this section will be 80%
  • section 3 will be 5 questions based on the High Way code - the pass mark for this section will be 80%
  • section 4 will be 5 questions based on routes and locations of places within Three Rivers District area - the pass mark for this section will be 80% 

The operator licence test will consist out of 20 multiple choice questions. This test will cover the Hackney Carriage and Private Hire Policy (pdf) in relation to Private Hire drivers, vehicles and operator licences, as well as the relevant law and legislation regarding private hire. The pass mark for the test is 100%. 

There are no specimen tests to view or study. This is because we want licence holders to have a genuine and thorough knowledge of the subject areas being tested and we do not consider this can be properly achieved or gauged where applicants are able to memorise a select number of questions and answers.
