What is Stage 6 of the Knowledge?

The final exam. For All London candidates it is five questions on the suburban routes in the Blue Book, at least one to or from Heathrow, naming every road and turn, and all five must be answered well. It comes about six weeks after your last Stage 5 appearance.

Checked against TfL's documents on 3 October 2026.

All London

  • About six weeks after your last Stage 5 appearance.
  • Five questions on the suburban routes in the back of the Blue Book. TfL's web page says there are 25 routes and its 2022 booklet 27.
  • At least one question starts or ends at Heathrow.
  • Name every road and every change of direction, ending at the high street or main point of the suburb, or the station shown.
  • To pass, all five must be answered satisfactorily.

Suburban

Part one: four questions from a major rank in your sector to a major transport hub, all four satisfactory. Part two: ten central London points from a list you are given at the end of Stage 5, at least six of them satisfactory. You pass both parts, and also need the way to Heathrow and London City Airport.

If you fail

The wait before a re-sit depends on your score and attempts, and may be as little as two weeks. Fail three times, or leave it longer than six months after Stage 5, and your Stage 3 to 5 knowledge is assessed again.
