Got flashed on M1

[legendracer]

At around 11pm southbound on M1 near J15-J14, close to Milton Keynes got flashed when the NSL showed 60 but was doing 70.

Not once but twice. First 60 was missed as it came up fast and it flashed and second 60, I just went through to check and it flashed again.

Before also we have crossed at 70 when it showed 60 and it never flashed.
This was set for a very small stretch even when traffic was less.
What would be the consequences? This has never happened before to me.

Thank you

Was this a variable speed limit section?

If your doing 70 in a 60 then I’d expect a letter from the local constabulary.

Speed awareness course, and no points. No biggie.

Oops!!

At an indicated 70 you may well be under the 10%+2 threshold. The flash suggests not though. Two weeks to find out...

If by “it came up fast” you mean the limit changed suddenly then you might be OK as there’s a short delay before you’ll get done.

I have to say, if you routinely drive through at 10MPH over then you’re asking for trouble.

It was GPS 70.

I had thought that even though it shows 60, cams are activated only at 70 and hence surprised at the flashes.

Ah. Look on the bright side, a lot of the courses are online now.

Was hoping for something else from title.

So you thought the cameras flashed at 70 so you set your cruise at a GPS 70?

Expect 2 letters on the post. Assuming that you stayed in the motorway and there were no changes to the speed limit between the 2 sets of flashes then they can be treated as a continuation of the same offence. You are provably going to need to talk to the ticket office about that.

The cameras adjust to whatever the displayed speed limit is. Most people set their cruise to the limit + 10%.

Haha. Never got lucky from a woman for roadside flash.

Yes. My bad. After 1st flash I could have reduced to 60 but continued in that cruise control thinking that flash might be a random trigger.

Yes. No change as it was on cruise control at GPS 70.

This M1 section was a newly developed one and hence I assume cams work perfect coz, last year I had crossed at 70 in a 60 but didn't flash.

I’m intrigued to know why you thought that?

There wouldn’t be much point in variable speed limits if the was the case. The ones on the M42 are legendary for catching people at 46 when they’re showing 40 for no reason at all (other than to fill up speed awareness course places).

Bad luck - was coming back from London last night, and it was annoying that the entire M1 from Luton to Nottingham (except the non-variable bit around Leics) was 60 for no reason that I could fathom. With the amount of flashing, you'd think there was a thunderstorm. You weren't the only person to get flashed twice last night!

You'll know as an engineer that when your car's on cruise, it's a PID controller at the end of the day, so it will occasionally overshoot by imperceptible amounts as you enter down gradients. If you have an analog speedometer, it's difficult to know whether your indicated speed is a low 70 or a high 70. And if you have a digital speedometer, 70mph may represent a rounding precision as much as 69.5 to 70.49. This is why you'll sometimes get flashed when travelling right on the margin.
