Going through a section of the M42 today.
Off the M6, onto the M6 toll, you pass through a section of the M42 which I wasn't aware of.
I went under about 3 overhead gantries which have the variable limit, they were off so the limit was 70 as normal.
Noticed they have white lines marked out for gatso/speed enforcement afterward.
Do they only operate when the gantries are live? A bit of searching shows they only have a few cameras and rotate them around the gantries, though this is true I don't know. Everyone around me was going fairly quickly, and I didn't see any flashes or anything.
