For sure they need to warn you but the warning can be ten miles earlier.
As long as the sign says "speed cameras ahead" or "speed camerasnext ten miles".
And no, AVERAGE speed cameras can be any colour they like, it's only the Gatzo type that need to be black and yellow. Most of them look just like traffic monitoring cameras.
But as Becky pointed out, and as I will maintain (see my earlier post page18 of QOTW) we all know the speed limit so don't twine if you get points for speeding!
As for the White stripe, you generally find them a quarter or half mile apart so the Feds can do an accurate time check on you.

I'm absolutely disgusted with myself
but I'm totally agreeing with you.

You disgusting man.
Although I'm sure you always stick to the speed limit when driving.

DISGUSTING

Ahhh,
This is the thing... there were no signs - at all - I'm certain of this.
I understand that average speed cameras *can* be any colour but the standard is to have them bright yellow (as evidenced in the 50mph zones on the M1 further down). I just thought it was strange seeing what seemed to be Traffic Monitoring cameras with the white Gatso lines a little bit further away.

up this end of the m6 the cameras are neutral black/blue.
and there WILL be signs somewhere, it's just you haven't noticed them. they could easily be 20 miles down the road.

AND I TOO AM DISGUSTED!
BECKY, AL AND BLAIREAU IN ACCORD SHOCK!
(did you see what i did there? Accord!)

BAN THIS SICK PEER BASED FILTH!

The
black and blue cameras on the M6 are TrafficMaster cameras, monitoring traffic flow, not speed.

All fixed speed cameras, including the SPECS averaging cameras in roadworks are yellow.
