This happened a few years ago but I have always wondered, The first time I took my driving test I got in the Car and as my mind was so busy remembering how to drive away properly having to do everything correctly, I forgot to put my seatbelt on and I didn't notice untill about 20 seconds after the car had pulled away, The test instructer did not seem to notice so I did not put my seatbelt on for the remainder of the test because obviously then he would notice that I was not wearing one and fail me, I ended up failing anyway on the 3 point turn. I was just wondering would it have been an automatic fail if I had of put my seatbelt on a few seconds after I had drove away during my test as its not really a driving fault? And wasn't putting anyone in danger except for myself. Another reason I was thinking the instructer maybe failed me on something silly after he noticed I was not wearing my seatbelt but didn't want to say it was due to the seatbelt incase it got him in trouble for not noticing at first.
