It's been a while since I took my test; is there no need for anyone to know road signs, speed limits, stopping distances (however outdated they are), how to negotiate roundabouts and junctions, etc?
You actually need to know it far better than those of us who took it a while ago. It's needed to pass the theory test which has to be done first. I don't think you get asked questions in the actual driving test though (like you used to before the theory test was brought in).
