I have actually used the 'turning left' hand signal when were stopped at a traffic light on a bright sunny day, people behind me might not have seen my left indicator flashing, so I learned, if its a bright day, people may not see your indicators so its wise to use a hand signal. I never see other drivers using them, only cyclists.
The arm signals here are simliar to the ones back home.
Yes, it is harder to pass with the introduction of the hazard perception test. I studied for two months and I still barely passed the HPT, I got 46/75, the pass mark is 40.
I go on a learner driver forum and a lot of people on there have trouble passing the HPT as well as the multiple choice but they tend to miss the multiple choice by only a little whereas they tend to miss the HPT by a lot.
BTW, they are adding a simple mechanics portion to the practical test as of September 2003 so if I fail my test in July I'll be stuck doing that by the time I get another test appt.
