I wonder if somebody could help me- I drove onto the A40 at Perivale observing the speed limit- I stopped off at the BP station at Park Royal for 5 minutes then carried on my way- still observing the speed limit - when I got past the Acton traffic lights I was still doing the observed 40mph however on the slope up to the white city turn off I has to accelerate to 52mph to avoid a complete idiot in front of me and this was just after the speed camera that is before the slope - I reduced back pretty quickly and maintained 40 then 30 onto the marylebone road
Will I be done for speeding for this momentary acceleration between 2 cameras or will I be averaged out over the entire distance of my A40 journey.

Well i hope you don't, however, i would love someone in the know to explain how average speed cameras work.

Do they average you between points A and B or if you stay on the road passing several A to D for example do they average you across 3 cameras? With the OP's scenario does it average your time on the road or take into account and delays eg services?

I had the misfortune to head M6 north a few weekends ago to Oulton Park (BTCC) & spent the first hour doing 50mph on a 3 lane motorway while passing some cones no one was working on (Sunday) for 50 miles, then as soon as it ended everyone speeded up & then there were low mounted SPECS cameras passed whilst completing an overtake. I wondered how these work as the next few i passed i was back in traffic doing 40-50mph - do they switch them off, average a whole journey or points A to B ie camera to camera?

I will also add how dangerous these SPECS cameras appear to be under the guise of safety, as soon as the low slung hidden but yellow cameras were spotted it was too late so most folks braked hard even those going below 70 which i felt was extremely dangerous & must have caused numerous accidents previously.

How does accelerating to avoid someone in front of you work then?

It was a foreign lorry driver who was veering between the slow and middle lane backwards and forwards and who had a back tyre that was deflated and he was trying to control his vehicle.
I was in the slow lane there was nothing coming up behind me so I accelerated from the slow to the fast lane to get past and in front if him in quick fashion.
The vehicle was that wieldy I was concerned it might fall onto its side
It was clearly full of something but wasn't marked- I think it may have been a removals van from the continent but the driver didn't even think of stopping off but instead I saw in my rear view mirror that he was still making his way to The Westway and Marylebone

I am sure they have the ability to fine you for excess speed between any two pairs of cameras.

If for example you pass four cameras (A, B, C & D) and exceed the average through all of them then in theory you could be fined for A-B, B-C & C-D!

They have to be able to do this in case, as you said, there are stops such as services in the middle of the camera runs.

It's gone past the 14 day period and haven't recd anything - would have got notification by now
I think that if your vehicle is registered from the Polish war memorial to Marylebone - it must obviously average you out- I therefore reckon I must have averaged about 43mph

The average cameras can all be off, all on, or a combination of the two. If you are caught on two cameras then it will calculate your average speed between the two.
If most of the cameras are active and you are timed at several cameras then it can calculate averages between any two cameras. If you passed 4 live cameras then that is 6 different average calculations that *could* be done. Whether they do will be down to the system, software and configuration used.

Best thing for average speed cameras is to set your cruise control or limiter to the speed limit +5 or less.

And accelerating to pass a swerving hazard doesn't sound like an excuse that would fly in court. I'm thinking they'd expect a more sensible course of action would be to drop back and maintain a safe gap.

Im sorry but as a highly qualified driver with advanced motorist and a gold ROSPA qualifications--i assessed the situation and took the necessary action.
You werent there. My action was to get past safely and which necessitated acceleration to do so.
Any unstable vehicle, which this was, could have , at 40mph veered over and hit the tarmac splitting the aluminium van structure and the entire contents could have spread all over three lanes in front of me. Well no way was i going to be a part of that!

I've always thought they are quite simple. On observing the warning sign and the speed limit, enter the ASC zone and keep your speed at or below the posted limit until passing the last ASC and the NSL sign is clearly visible.

So as a highly qualified driver you thought the best way to avoid a vehicle with a deflating tyre and veering across the road was to accelerate past it, and not to stop. Where did you get your qualifications, After the fact dodgy excuses limited?

That's ridiculous

Indeed. The more prudent course of action would be to maintain an appropriate distance and call 999 to Alert Trafplod. I wouldn’t get caught trying to squeeze past a veering lorry on that stretch.

Also, please explain what you mean by slow lane and fast lane? I was under the impression that the lanes are numbered 1,2,3 or left, middle, right?

For an awful moment I thought You’d call the 3rd lane ‘the overtaking lane’

Eh?? Didn't ROSPA bother to point out to you that your car is fitted with brakes?

Well there's two self-confessed overtaking lane blockers.

Did you get your amazing driving qualifications in a box of cornflakes?

A truck with a deflated tyre is not something it's sensible to try and pass, especially if it's already swerving.

I think what you meant to say was that you took a risk as you didn't want to be stuck in a traffic jam for ages. Braking to give you a big distance would have been the safest course of action.
