For all tests, you will embark on a 1-hour drive, which will be marked against the same criteria that your initial driving test was. You will also be asked to complete a reverse manoeuvre, which will be conducted at the test centre and can be before or after your test. If you have chosen a D1+E test (with a trailer), then you will also be asked to show the examiner how you would uncouple and recouple the trailer.
Below is a diagram that gives you an idea of how your examiner will expect you to complete the manoeuvre. For those taking a D1+E test with a trailer, the distance between cones B and C increases from half a vehicle length to one vehicle length.
