Average speed camera lies?

[twoblacklines]

Near Plymouth there is a 3 mile section of average speed cameras on the A38 towards Ivybridge. They have been on for months with a 40mph limit (in a 70 zone!).

For the last few weeks these have still been there. However there is a sign that says "Cameras are turned off". But this is a yellow one on a removable stand on both sides.

What makes me "wonder" about these cameras is there are floodlights where they are so it can register number plates. These floodlights are ON at night time and dusk etc. Also there are new cctv cameras built in aimed at the average speed cameras. These were not there when the construction was being completed.

If the cameras are turned off why would the floodlights be on, only where there are cameras, when it is dark? And why new cctv cameras for average speed cameras?

They are concreted into the road so I think they are a permanent fixture.

I ask this because I joined the a38 at some speed from a slip road earlier and it is not clear you are entering the "zone" from the sliproad.

If I got prosecuted how would I even prove the signs were there on the day I got prosecuted? They could easily lie and say the signs were not present x days in the past.

The signs are on these kind of stands

These cameras are there because they are replacing a road bridge over the A38. Until recently, the new bridge was being constructed so a 40mph speed limit and contraflow was in place. The work to construct the new bridge is now complete from the A38's perspective and has progressed to the road above. So, the roadworks are gone and the cameras are turned off.

Once the new bridge is opened soon, the roadworks will go back up for demolition of the old bridge. This is why the cameras have not been dismantled, as presumably they'll go back into use.

This is all there is to it.

Is that the saltram bridge or another one?

Why was the 40mph limit so long after said bridge? I don't understand the need for MILES of slow traffic after the actual construction zone.

It has been a while since I have been up north but there used to be the same above Bristol...miles and miles of 50mph average speed cameras but only a few hundred meters of actual work...Smart Motorways I believe.

Same on the A30 now... 40mph limit 4 miles before the actual work... including 2 downhill sections so cruise control doesn't work :S

I was under the impression that the floodlights were there to illuminate the cameras so people could see them, not to illuminate the number plate/driver. The IR illuminator is either next to the camera itself or integrated into it. However, I have heard of some that aren't floodlit.

But the illumination is on the road where the cameras point, after the cameras, not on the cameras.

At one part of this road the cameras are hidden behind a gantry of sorts so you only see the floodlights and not the cameras at all.

It is currently a 50mph limit again all the way down Deep Lane :/
