Another question to the knowledgable of this communtiy.
do the variable speed cameras on the motorway flash when they take a photo of a speeding vehicle?

I ask because I have never seen it happen but the other day I was driving on the M62 in rush hour traffic and a couple of times I seemed to notice a flash, (Not at my by the way). as I say, I've never seen that before. does anyone know for certain?
