don't worry, lots of ppl fail on 1st time..I fail it too....I had a instant fail when I driving back to the office which is nearly finish the whole test....
so don't give up....try again.....I don't familier with HK traffic exam system, do u need to go drive on the road ?????
coz the traffic in HK actually very messy and really lot of cars and ppl...they don't watch sign.....so I think it will be easier to take it in Australia...
