'Hidden' speed cameras introduced in the UK

[Sir Fynwy]

10% + 2mph

Exactly, the guidelines for prosecution on a 70mph section state that people shouldn't be prosecuted at under 79mph in normal circumstances

Yeah, I've seen that quoted before, but is it universally applied?

 

I know this isn't motorway cameras, but ages ago, I heard that speed cameras in Leicester were calibrated to be triggered at +20%, more generous than elsewhere, and this seemed to be borne out by the fines my friends were getting - nobody seemed to get caught doing less than 36 in 30 or 48 in a 40.  No idea if this was true or is still the case.

 

I'd be a bit wary of testing the margins, so to speak, but then again, I've always been a cautious cat

I know the officers that are standing at the side of the road with a speed gun can give you words of advice for any speed over the limit and up to 10%+2 but as soon as its that limit they can report you as otherwise the prosecution wouldn't be supported.

And I got done at 58 in a 50 in 2011, which is less than the 20% you mention.

It was a long time ago that I heard about the 20 per cent thing.  Maybe it was the case but they've tightened up since, which is the way it usually goes, isn't it?

Thats a coincidence, i've been done for 58 in a 50. Something dodgy going on there.

MrsG got a ticket for doing 34 in a 30 limit which was snuck in between a 40 and 20 limit entering some rural Sussex village at 7.30 on a Sunday Morning when we didn't see another car for about 5 miles.

Legally you can be done for doing 30.001 mph.

 

The 2mph is the tolerance for speed detection.

 

The 10% is a bit of leeway usually granted when setting speed camera thresholds.

 

It should also be noted that car speedometers must not under read, so they actually over read by at least a few mph.

I did a speed awareness course last week. Apparently there is no set rule for at what speed they prosecute you for. Different forces have different criteria.

When I did the speed awareness course they said Leicestershire is 10% +2mph, other forces may well be different as Webbo said.
