Caught speeding within an avergae speed camera area

[PTR99]

I travel to work along a road where there are 40 mph average speed cameras. I was recently caught by a mobile camera unit travelling at 55 mph whilst I was within this average speed camera area. The distance between the two speed cameras, which then work out the average, is around half a mile.

Do I have a case by stating that I was within the law if my speed between the two fixed point is below 40mph, or do mobile units have the right to go wherever they choose to set up?

SAs Zac says,

Pay the fine and take the points, you have no defence at all.

As been stated, PTR doesn't have a case but I see where he's coming from.If there are cameras there already, why did the MCU set up on that stretch of road ?

Why a mobile speed camera within a SPECS zone? It could be the case that the SPECS average speed cameras are not operating at the moment.

Guy thanks for your answers. I know I was speeding towards the end of the average speed area on the day in question, but think that this was compensated by driving the first half of the stretch of road at significantly below 40mph. Anyhow, I've no problem paying the fine and taking the points, I just dont agree with the fact that there were two methods of speed trapping involved, one of which (the average speed cameras) has returned no offence and the other (MCU) which has.

You make the mistake in thinking that British Law bases the concept of speeding on an average speed rather than an absolute speed. Average speed is just one method of measurement - i.e. you cannot have an average speed in excess of 40MPH without having an absolute speed in excess of 40MPH at some stage within the SPECS zone. It is not relevant that you can average below 40MPH while occassional exceeding 40MPH.

In short, SPECS can be used as proof of a speeding offence but cannot be used as proof that no offence was committed

It, probably a ploy by the operaters to make drivers even more paranoid about getting caught speeding!

Your objection to two methods of detection being used is a little strange. It’s rather like objecting to one police officer being on duty in a store to detect shoplifting, and another on duty outside to catch those thieves running away.

In the average speed camera zone, what was the speed limit on the signs?

40 mph.

What is your argument with being done for 55mph then?
