The 10% threshold/leeway for a start. Bigger number=more money.
From a conversation I had recently with a speed camera operator he took the view that drivers really taking the piss (not his exact words) will get snapped as will those who just continued speeding having obviously not seen his van. Speeding drivers who HAD seen the van & had been able to slow down in time were less likely to get snapped. Perhaps he was a rare individual who saw his role as preventative, how long that attitude would have lasted is open to question if he had not been deemed as catching enough speedsters to meet some fiscal target.

I press on a bit quick myself sometimes but bless having cruise control & a speed limiter AND remembering to have the discipline to use them, yet I do not assume I'm insulated from being caught out.

The geometry between you and the van will also affect their reading. If your velocity vector is not pointed directly at the van, then the reading they received will be reduced. The more offset, the greater the reduction. Your velocity vector towards the camera is your real velocity x cosine of the offset angle.
I'm sure it's not that simple laugh

It does, but generally they are measuring from so far away the effect is negligible. Any variance from it works in your favour anyway.

Actually, it is. Your velocity vector can be divided into a vector directly toward the camera van, and another vector perpendicular to the van. The result is a right triangle, with your true velocity as the hypotenuse. It won't result in a huge difference because of the nature of the cosine function.

It's hardly this - the differential equation determining vehicle acceleration!

You should forget the 10% +2 as that is ACPO guidance only. You can be prosecuted for doing 31 in a 30 if the local force desires. judge

A colleague got a speeding fine for doing 64 in a 60 in Lincoln from a mobile van.

Caught yesterday by a camera van.
Sounds like you weren't necessarily.

Make sure V5 is registered to your current address and wait a couple of weeks to see what comes, if anything.

I was convinced I got caught at a similar speed 6 weeks ago. 8:30 am on a quiet Sunday morning. I got probably within 70 yards of the van before slowing due to having my eye on a vehicle that had randomly pulled out. Checked gps after and was a likely 35mph; no news 6 weeks later so think I am safe.

Who me ?

NO- Scamera lot don't want folks above the course / penalty limit, as they don't get any funds from this to uphold the empire. They NEED bums on courses, or FCN payments to keep the Empire financially viable.
I've always wondered how long it would take this lot of vultures to admit defeat( and go bankrupt) if all UK drivers kept to the limits.

With that being said, a different copper could have the exact opposite mindset and be more wanting to punish those who have tried to slow down in the same way as those still pressing on at speed.

To be black and white about it, you're still speeding and it is an offence to do so. The main issue is that, for the most part, by the time you can physically see these vans then it's usually too late.

It's a bit of a false premise i think, seeing as most coppers seem to work differently. There are so many stories out there of people that think that they've been caught speeding but never heard anything back.

That isn't my experience. 46mph in a 40. It had been a 50 and my TomTom said that it still was. I saw the van when I was half a mile away and only exceeded 40mph when I was far closer than you'd expect them to be targeting you, considering their excellent placement.

My calibrated speedometer said 45mph. They called it 46mph, the prosecution threshold, and offered me a SAC. It took it because of the vehicle type that I had been driving. Hard done-by but it could have been worse.

Little choice but to sit it out for a couple of weeks and see if anything unwelcome drops through the Registered Keeper's letterbox.
That's two and a half weeks now. Not heard anything. I guess I was below the threshold. Phew!

What do you base that on ?
The fact I got done last weekend on a sunny sunday afternoon, quiet dual carriageway, outside of city/town limits and I was doing the obscene speed of 80mph in a 70 zone.

Big number indeed grumpy

Cruise control or speed limiter is ideal for preventing this sort of worry (road and traffic permitting).

Of course never mention it on PH or the "all driving aids should be banned apart from the ones I like" contingent will appear.
Yep. I use my speed limiter in all roads up to M-Way, then I tend to use cruise control. Most 30 limits around here will have a camera van once or twice a year.

Nope, in Northumberland. And why should I provide proof?

Because so many people have posted on here about getting done 31/32 in a 30 and have never provided proof thus everyone thinks it's a myth as it basically never happens.
