M6 Southbound, J19

[crazylegs]

I was heading southbound on the M6, about to come off at Junction 19 earlier today. I sped up to overtake a lorry in the inside lane, and to my horror saw some lines underneath me as I was doing about 80.

I looked in my mirror and couldn't see any roadside cameras, and there were no bridges nearby. Are these lines from previous scameras at roadworks, or should I expect to get NIPed?

No small children were killed in the making of this post.

Those lines are ancient history, from previous roadworks, I know I drive down there most weeks.

Cheers guys, mind at ease!

There's still SPECS on and around Thelwall viaduct - 40mph limit.
