Average speed cameras do they work??

1886

These vehicles that go racing past at 60mph in the 40mph average speed check, I believe these to be the same vehicles that are sat at the red light when I pull up next to them

:P

The ones on the M3 dont work!

I saw a scrap metal collector fly through at about 80 yesterday all the way. I suspect his address is pretty vague and no enforcement company would ever bother to try and collect. I'm not sure how they enforce temporary tourist or shred vehicles either.

I assume, based on the fact HGV's don't slow down for the ones with a "50" designation, that the collected wisdom is that they won't trigger unless you are over 56mph.

If you mean the ones between Hook and Farnborough, I can assure you they do! A guy at work has a ticket for doing what he called slightly over 55. Could have been 70 knowing that heavy footed numpty though!

I'm not sure whether they are a SPECS. They are the ones with the tall yellow poles holding the camera which are set at intervals along the road. They are set up specifically for the road work areas. They also have them on some national speed limit roads too.

Yes these sound like SPECS camera's.

I usually go through them at just over 55mph on my speedo unless I don't think the conditions are safe enough or traffic prevents me. This equates to around 52-53mph on the sat nav. I have done this ever since having read the below article, and touch wood haven't had a fine several years on from any motorway average speed cameras.

The answer is yes, though as above , the speed threshold will probably nearer 60mph.

The trouble is that a lot of drivers don't understand how they work so they slow down to go through the 1st sensor and then speed up.

In fact you could go through the 1st sensor at 100 mph as long as you then slow down enough that your average between any 2 sensors is under 50 mph.

The vehicle is registered by number plate recognition going through the entry and exit sensors and a computer works out the average speed.

I've met several people now who believed they worked by taking the average of the speed readings. So they thought as long as they were doing 50 at each camera, they'd be fine doing whatever speed they wanted in between. :wall:

Actually I was referring to the ones at the top of the M3 after you come off the M25, i've forgotten about them numerous times and gone through the whole 50 area at 75 and not had any fine.

But thanks i'm going the M3 hook way tonight so will take it easy there.
