You can do this before youu2019ve passed the theory test.Take and pass the practical test. You will have to have passed the theory and hazard perception tests before you can take the practical test.Congratulations, youu2019ve now got a Category C licence.There are some extra bits you need to do if you want to drive commercially (Driver CPC), but these are detailed on the link above.
