The Driving test includes a period of "Independent Driving". Don't worry the examiner is not going to get out and let you drive the car whilst he goes for a cup of tea!
What will happen is this. You will be asked to drive for approximately 10 minutes following:
- a series of directions
- traffic signs
- or a combination of both
The aim of this section of the test is to see you plan your drive - deciding when you need to change lanes signal and generally prepare for the junctions ahead. It is NOT a test of your navigation skills. If you take a wrong turn you will not be marked down. That can happen to the most experienced of drivers.
