Like most government departments, the Driving Standards Agency (DSA) – the body charged with driving standards and therefore the running of the testing process, publishes its operating procedures, including those pertaining to Driving or Riding Examiners.
Whilst not the most interesting or easiest of things to read, the DSA’s “Standard Operating Procedure – For the guidance of all examiners carrying out car, motorcycle, taxi, large goods vehicle, passenger carrying vehicle and extended tests” document outlines how your driving / riding test will be conducted and what the examiners are looking for. If you’re the sort of person that likes to read everything you can before taking your test, then here it is : http://www.dft.gov.uk/publications/dsa-dt1-standard-operating-procedure/
Its handy to see whats expected though beforehand, rather than going in blind.
I know when i took mine i just wanted to steam through it as id been riding over 20 years by that point.
But on reflection i should have tried to get more out of it.
Although, that was partly down to where i did my instruction.
