Community Speedwatch Volunteers are trained to use the equipment by Police Officers from Traffic.
In Wiltshire, they are normally only positioned in our rural villages, only in 30 and 40 MPH zones during daylight hours and if it isn't raining, where concern has been raised over speeding motorists. (an all-encompassing term that includes motorcycles)
Wiltshire Police allow 2 MPH + 10% , so the CSW bods will only note your number if you are doing over 35 in a 30 and so on.
One strike and you get a letter.
Two strikes and you get another letter.
Third strike you get a visit from a nice Policeman.
It's down to them if they prosescute.
Try to imagine how you would react if it was your child who had been mown down by a speeding motorist, whilst on their way to school or the playground.
A personal view only:
Respect the urban areas, especially when you know people are about.
When you are on the open road and conditions allow, do what you like as long as you don't act like a knob.
