Hi there. Yesterday I drove up to York and parked as I usually do to visit the NRM, right next to my car park on Carlistle street there are roadworks with temp lights, what caught my eye is that next to the usual "When red light shows wait here" sign there was an additional "Traffic enforcement cameras" sign next to it. After parking I went to examine the lights and site on foot but found no signs of any actual cameras. That got me thinking if this sign is literally just there as a scare tactic/deterrent to stop people from thinking about jumping the lights?
Here is a pic of one end showing the lights and signs mentioned.
