DVSA Video: Observer on test
This video discusses the DVSA preference for you to have an observer with you on test..
When you take your driving test you might well be a little nervous - this is totally understandable and normal.
But, when we are very excited or nervous we are less likely to remember things in an objective and rational way. This means that if you are unlucky enough to fail the test you might not have a clear idea of what went wrong.
At the end of the test the examiner will offer an explanation - but again, if you have failed you will not be in the best state of mind to take the advice onboard. Many instructors sit in to listen to the examiner's de-brief but that only gives them a rough idea of what happened - especially if you remember things differently from the examiner.
You will get the best value if you instructor comes along.
If you fail he/she will be able to tell you exactly where and why, this will help target future lessons to ensure that the errors are not repeated. If you pass the instructor will be able to see how you drive 'under pressure' and this will help to ensure that you get the best targeted training when you take your Pass-Plus course.
