Taking the test

After you apply for a hackney carriage or private hire driver's licence, you should contact our licensing team when you are ready to sit the knowledge test – you can do this at the time of your application, if you feel prepared. You will then be given a date and time to sit the test at our Civic Offices in New Road, Grays.

At the end of the test, your result will be displayed on the screen. If you pass, and all other parts of your application are satisfactory – including DBS disclosure, medical results and PATS certificate – you can speak to the officer at the knowledge test about when to collect your licence and badge.


The following conditions apply:

  • your application fee allows a maximum of 4 attempts at the knowledge test
  • there is a fee for additional tests that must be paid for before you take the test
  • if you are not successful on a particular test, you will only be expected to answer questions on the sections you did not previously pass
