Variable Speed Cameras

[MattADH]

Do they actually work? I have to go through them regularly, adhering to the limit but I have to wonder if they are active?

It seems either some cars are not affected by them or they know more than me in that they are inactive and just a deterrent. I dont know anyone who has been given a fine for speeding in a variable speed limit zone.

I look forward to hearing opinions and views...
