Bloody sodding bloody....!!

[Mr Tidy]

Really sorry to hear that John.

And it does put a potential speeding ticket into perspective.

Still on that topic I try to avoid the M1 whenever possible, but would 78mph really trigger the cameras?

I use the M3 and M25 quite often and they have cameras every 400yds or so, but anything less than 80 on the speedo has always been OK. Mind you I usually prefer to go a slightly longer route on the A3 as it has no cameras! :lol: Although it does seem to be patrolled more, probably for that reason!

I'll keep my fingers crossed for you.

Well we live and learn...I didn’t think smart motorway cameras fired when there was no speed limit displayed but that’s not true..here’s a picture of a car being ‘caught’ on a non displayed limit motorway..in fact it hadn’t shown a speed limit for over 12 hours..

Remind them it’s Black Friday,they might cut you a deal. 8)

I’m sure the cameras flash twice to capture the distance covered

I thought that too. I was lead to believe that’s why the lines are painted on the road so they can prove the distance travelled between the two flashes as backup for the speed reading if its contested

Sod's 254th law. Let"s hope it was the guy behind you. Else another first World lesson learned.

:? Surely motorway speed limit is 70 unless stated otherwise regardless of wether the speed limit has been displayed no...? If not that would mean the speed limit would have to be displayed at every single slip road, unless I’m missing something...?

No lines there chaps, I guess new cameras don’t need them perhaps..? I have no idea tbh. The camera did flash twice as Chippie says but I’m assuming it caught us both.

You would hope there would be flexibility when they start using the matrix signs, the speed limit can change by 20/30 mph very quickly but 70 is the limit and we dont need a reminder of that but i 'we' often take our chances. Be very embarrassing for me as my employers would very dim view of it, wrong side of a magistrate !!

 

[MrPT]

Amazed they flashed at an indicated 78mph. That’s well within the usual tolerance.

78 on the cruise control, so...what...75 corrected real speed Mr PT...? It’s over 70 so that’s it, busted no...?

John this will probably confuse the issue but nosiness got the better of me after saying to you about the two flashes so I had a look to see if I was talking sh!te and found these

If it’s the HADECS speed cameras as found on smart motorways they don’t seem to flash

Do Hadecs speed cameras flash?
Answer: There is no visible flash emitted by HADECS 3 speed cameras. The unit next to the camera helps to provids an invisible infra-red flash to aid the camera to operate at night and in low light condition.21 Oct 2020

If it’s not one of the above and was a fixed Gaston type camera, it’s what I was referring to earlier and flashes twice (from the AA site)

1. Digital Gatso speed cameras

The Gatso was the first speed camera used in the UK when it was installed on the M40 in 1991. The boxes initially used film to capture speeding drivers but now use digital photos.

All Gatso cameras are rear-facing so that the flash won't dazzle drivers. The flash lights up the car and registration plate as well as white lines painted on the road in front of the cameras.

The camera takes 2 photos in quick succession. The camera compares the car's position on the white lines in the 2 photos to work out the speed by the distance covered.

The only caveat I’m putting on the information above is there may be another type of camera than the ones I’ve quoted above.

But more hopefully, if your speedo is reading was 78 mph then it was the guy behind you

At what speed do motorway speed cameras flash?
Most police forces have a tolerance of 10% plus 2 mph above the limit before a speed camera 'flashes'. So on a 30 mph road, a camera wouldn't normally activate unless a car drove past at 35 mph or above. On a 70 mph stretch of motorway, this threshold would go up to 79 mph.30 Sept 2020

 

[Wyldie85]

Blimey. Three pages of man admits to speeding and camera goes off. :evil:

 

[TitanTim]

I like a good speeding ticket thread with possible imprisonment

They also test flash, I got flashed on the M25 doing 70 as I knew it was there. Heard nothing of it. I really think you will be ok.

 

[Dav the wheel nut]

Ahhhhhh.....well tbh I went on one last year Zebedee, another one off slip up.

Ah so you’re a serial offender oke:

 

[mr.tourette]

10% plus 2mph is generally the tolerance for speeding so 79 mph is usually the limit for a ticket in a 70.. you may have dodged a bullet but its borderline

There's a camera on a 60mph limit road near me. A couple of months ago it flashed me at 56mph

The point I was trying to explain is that there are times on smart motorways when all the gantry lights are off...so yes the National limits apply..

However often when the gantries are active they re-display the 70 mph limit post a period of slower traffic control .. sometimes they show a National limit sign...the point being is that the system is obviously ‘active’ as opposed to all dark n silent..but as discussed just cause they are dark doesn’t mean they aren’t watching..

Its not just the flashing cameras but they have HADECS Radar up most the M1 now and especially the new section in Yorks
If you dont know already check out :
https://www.speedcamerasuk.com/hadecs-3.htm

Sounds like it wasnt a SMART section of motorway if it flashed.
You may and I say may get away with a course at 70 Mph +10% +2mph so 79MPH.
I was in Yorks on the M1 and was done in a 50 section for 56 and got a SMART Motorways awareness course but no fine.
Had to wait over 6 weeks to get a course.
They can catch 3/4/5 cars abreast all at the same time with no flash and no road markings.
Look for the 2 grey cameras on the LHS of the Gantrys.

Good luck - its a bummer!

That’s a hell of a post Andy.... :lol:

What I failed to say was the flash was not behind me, I was tired and didn’t think of it last night, it was pretty much right on the car if that makes sense, so I’m thinking it was the North bound outside lane camera that flashed perhaps..?
