His local driving test centre was chosen as one of 20 in the UK to trial the revised practical exam with the help of a GPS navigation system.
The examiner set up a route on the device for the first twenty minutes of the test and Grant followed the sat nav verbal instructions - with the instructor still in the vehicle.
The Driver and Vehicle Standards Agency (DVSA) expects 1000 learner drivers will take part in the revised tests which are set to continue until the end of the year. If successful, it could be the biggest shake up of the test in almost 20 years! the last big change was when the written theory exam was introduced in 1996.
