Free Traffic Legal Advice

I assume im bang to rights but thought would add anyway just to make sure. The officer was hidden on the bridge not in the middle but to the far left pointing at an angle, I assume as its a motorway they don have to display speed camera signs as its a national speed limit, there was no van or nothing just saw the man last minute and I was obviously going to fast. Thanks in advance.

Just too fast for a speed awareness course, but I assume you did one anyway last year for your 35 in 30 incident? So it will be a £100 fine plus 3 points.
