The first key change will be the provision that P1 drivers will have to complete the Hazard Perception test before they can be allowed to proceed with the driving test.
Furthermore, once a P1 driver has been accredited, they will no longer be required to pass the hazardous perception test again before being issued with a P2 driving license. A driver who has been able to hold a P1 driving test for at least 12 months and has already passed the hazard perception test can be issued with a P2 driving license without having to take another hazardous perception test.
The authority is also doing away with the Driver Qualification Test and this implies that if you have had a P2 test for more than 24 months, then you can go ahead and apply for a full driving test without having to undertake any additional tests. Note that this only applies for P2 licenses that will be issued from 20th, November 2017.
