When I was a newbie on the Traffic Dept I went out one day with my Skipper to do a bit of local familiarisation. I was fairly confident (as you are) at one point and started to 'wind-up' for an overtake on a relatively short stretch of road that led into a right hand bend. My skipper, bless him, turned to me and, gently placing his hand on the gear lever, said "Whenever you're thinking about an overtake, always imagine that I'm coming the other way on a shout"** I have never forgotten that advice because I feel it is one of those gems of insight that keeps people alive. One of the other insights I learnt from those days was "The more paint the more danger" Solid white lines are there for a very good reason! **My skipper was the smoothest, fastest and safest driver on the department, what he could do with a car was amazing and if I was ever in dire circumstances (which I was on a few occasions) it was always a relief to hear that my skipper was 'making progress' toward me.
