Speed Camera Trigger Speeds

[Strommer]

If you've been caught by a speed camera in a 40 zone.....what was the recorded speed?

I'm asking as I may have been nobbled at 47 (speedo) ... and am curious to know the likely outcome...

NB - 'twas London bound A40 approaching Hanger Lane - so any info on that camera might be useful.

3 points £60 fine, me thinks.

If you were going at 45 on the speedo you'd probably be OK as the Wee's speedo is a bit optimistic. 30mph is about accurate on the speedo (maybe 29 in reality.) At 43-44 indicated you are doing 40 in reality, after that it's about 10% out. So at 77mph indicated you are at 70mph in reality and at 110mph indicated you are at 100mph (just for interest's sake...)

So if you were on 45 on the speedo you'd be at 41/42 in reality and they normally don't catch at that tight a margin. Hope for the best

Just happened to test my speedo against my gps yesterday, all on long straights.

Speedo read 45mph, gps read 41 mph
Speedo read 60mph, gps read 55mph
Speedo read 80mph, gps read 73mph

Thought I was doing 40 - double took and it was nearly 50 - so I caught it at 47-ish and gave the rear a flat spot...baaah

My speedo is also pretty inaccurate so my 47 was probably 43/44

The given figures are speed limit plus 10% plus 1 so at 45 you will get a ticket if you are lucky you will get offered the defensive driving course will cost you £70 but no points if you have been caught before then 3 points and £60 however if as you say the speedo was reading 47 allowing for the the incorrect reading of speedo you were probaly going at 42 / 43 and also the fact you didn't see a flash you should be OK

Nail-biting two weeks then....  there's also a possibility that a high-sided vehicle on my left obscured the GATSO.

It's a PIA as I was just putting on a tiny spurt to get out of the shadow of the high-sided vehicle to be safe...

So I guess there's a few things in my favour:

- it's in England so ACPO 10%+2 (or 1?) may apply
- the high-sided vehicle may have screened me
- first (possible) offence in 20 years on the road, so maybe a course instead of points - points bother me, the fine I couldn't care about
- I was probably doing less than I thought....
- It's a 3 lane road so it may not have been covering my lane (though as it was the outside lane it probably was...)

On the down-side - it's a tricky turn-off that the GATOS covers so it's likely to be set low...

The association of Cheif Police Officers guideline is 10% of the speed limit + 2 mph. But this is a guideline and not set in stone...

Despite flashing there's a fair chance it won't have actually had a camera in it, unless it's one of those new ones that link directly through without film.

[Strommer]

The ACPO thing is interesting as it doesn't apply in Scotland.  There are two Scots members posting on this thread and two voted for the "below ACPO" limit.....  was it you two...?

I was flashed by the very same camera doing 50 plus, wouldn't normally be able to do it there as it is always so congested but it was 6.15 am on 3rd of January which was a bank holiday and no traffic.  Anyway I didn't ever get a ticket so I guess I was lucky, maybe no film in the camera. Hope you are as lucky.

(Slightly off topic)
A few years back whilst driving my car on the A1, just outside Berwick, at a steady 60mph (was crossing the marker lines of a speed camera) I was rear ended by a Range Rover which must have been doing 100mph, as it wrote off my 4x4 and nearly killed me. Still no idea how the idiot managed it as we were the only two vehicles for miles on a nice sunny day!

I later asked the cops to get the photo of the Range Rover going through the camera as evidence but was told that they never bother putting film in them. The police who attended didn't even charge the driver/passenger (who I saw changing places!) as they were apparently "diplomats" from some African state whom, I presume, we didn't want to upset. The cops also said that no one had been seriously injured, this whilst I was lying on the road with half a windscreen stuck in my head!. I successfully sued their insurance company but never found out their identities, but the compensation was irrelevant compared to the danger these people put me in.

Ta Vince, fingers crossed.

Not a speed camera fan.  On my commute (6k pa on the North Circular) I see minor accidents every week.  in 2.5 years I've only seen six really serious "cut them out" type accidents on that route...

...EVERY SINGLE ONE a shunt at a speed camera....

Day 14's post has just been and gone.... no ticket ...Hooray!!!  

Think I'll cover my number plate and "ton-up" past that camera with my arse out to celebrate....

Mind you a bit chilly today....

I would go with the 10% + 2 figure as well. Your speedo is likely to have been over-reading as my GPS always shows that to be the case. And if the 14 days have passed since the offence then so long as the bike is registered to you and there would have been no trouble with your address then it would sound like you are home and dry   Bloody things, I hate them despite being in the job. They do nothing other than fleece your average law-abiding citizen, alienate the police and give money to the government who would rather send it abroad than sort out problems at home etc.
