On your test, if asked to perform the turn in the road (three point turn) manoevure the examiner will expect you to turn the car round:
safely, smoothly, under control,
making proper use of the accelerator, clutch, brakes and steering
without touching or mounting the curb
The examiner will also be looking to see that you:
show good observation and are aware of other road users, keep looking all around throughout the manoeuvre.
Remember: on your test you do not have to perform the turn in the road manoeuvre in just three turns. Although you should aim to make as few turns as possible, on a narrow road you may need to take up to seven turns. So a three point turn can actually be a seven point turn.
