Decided to go along today to see what they said. After all, any advice is welcome. I was a bit concerned because my cans aren't stamped as road legal <cough> and I was wearing my dark visor, but he said that as most of them were bikers themselves, if I wasn't doing anything dangerous or silly, I probably wouldn't get pulled for those at all! Rather nice looking copper took me and a bloke out in a video car first, looking at hazards on the roads. Very useful. Then I was followed by a VERY nice policeman on his bike <sigh> who couldn't fault my positions or observations. The only thing he commented on was that I indicated to overtake cars and then indicated to move back in again. He said that these were unneccessary signals as drivers rarely saw bikers until they were level with their windows and moving back in was going to happen anyway. I saw his point. All in all, a very useful and helpful day...with men in uniforms thrown in as well....can't be bad ;o)
