This includes speeding, swapping lanes on roundabouts without mirrors and signal, going right from the left lane, not stopping for people already on or near zebra crossings.
All these things are automatically serious faults. At this point your driving test would be over.
You have to remember the driving test is a practical test – its to see if you can drive correctly for 40 minutes WITHOUT making any mistakes – If you cannot drive for 40 minutes without mistakes on your lessons – you wont do it on your test!!
