My mate failed test last week on something which suprised me let me know what your feelings are on this. Approaching a road where two seperate roads merge into a dual carriageway, she looked behind and sees nothing approaching from the right road. The trafic infront is doing 40mph on the 50mph dual, so she indicates to move into right lane on checking mirror before pulling out she sees a BMW tonking it , so she hangs back the BWM flashes her out and away she goes. At end of test examiner tells her , she should NOT have indicated as this caused the BMW driver to be in two minds and caused him to slow. Now I did my IAM advanced driving (car) a couple of years ago and was told this:- Indicate when u wish to tell people you want to pull out, do this regardless of who is in the right lane as if u wait for the right time youll be there forever. The examiner disagrees with this (I asked him) and he states you should not indicate unless its safe to do so and will not cause the traffci to slow. Either the IAM are wrong or the examiner is? Any of you clever chaps / chapesses steer me in the right direction. (I gave up my IAM subscription so cant ask them). Ken
