The six volunteers have been receiving training from police community support officer, Steve Trail (pictured) and started their work at the end of last week.
Dick Beardsall, chair of West Hill Residents Association said: “The first time we were out, last Friday, in West Hill Road, there was no one exceeding the permitted speed.
“On Monday morning, at Bendarroch Road/Moorlands junction, seven people were clocked doing 36 mph or more, including a bus. A white transit van was spotted travelling at 46mph – in a 30mph limit.
“The radar gun can pick vehicles up from quite a long way away, so not everyone sees us immediately, despite the hi-viz jackets.
“The response of passers-by, particularly pedestrians, has been uniformly supportive.”
