46mph for FPN, so about 48 indicated. You'll be fine.

According to your speedo, 45mph to be on the safe side.

FPN = Fixed Penalty Notice

yes, Fixed Penalty Notice, the alternative is court summons.

Most speedos over-read by 10%. So you'd have to be indicated around 48mph on your speedo to hit true 46mph and activate the camera.

In theory that's the case, yes, I always go past cameras faster than the limit as I know they won't go off but 48 on your speedo in a 40 is pushing it really. LIke I said 45 past a 40 zone camera and you will 100% definitely be fine.

It's generally 10% of the speed limit plus 2 i thought? Eg. for 40mph it would be 44+2=46.

about 45 before it goes off...

needless to say you were pretty stupid for going through it at 43mph anyway!

Yeah, the safest thing to do is go though them at the speed you are supposed to..

they work on 10% don't they?
So you would have had to be doing 44mph before it would flash you.
As people has said the speedo is not a true reflection of your speed, you shud always make sure your under that way you can be sure :biggrin:

the thing about modern speedos is that they are pushed up about 5mph off.
so say your going 70 mph then your actually doing 65ish mph.

10% + 3mph beofre the Police/cameras will bother.

Rumour is that some of the newer digital cameras such as on the matrix/lane control signs on the M25 and M42 have a 2 mph limit, are on whenever the matrix signs are active and don't use a flash so the first thing you know is when the FPN or summons arrives.
This is unconfirmed though but to be safe I stick to the indicated or below whenever there's a matrix lit or a white van with a big window/open door parked on the bridge over the motorway.

I read somewhere that it depends on the local police force/camera partnership. As someone mentioned, the most sensible thing to do is just keep to the limit going past the camera.
