Can anyone help me here, What’s the rule on where a mobile speed camera can set up. I’ve just been over the local level crossing and there’s a mobile speed unit there and out on the side of the road is a camera on a tripod. They have just altered the speed limit there in the last week or so. I thought all mobile cameras had to be within clearly marked speed camera areas and this one is not. I Think I was doing 45 in a New 40mph limit up until the other week it’s always been national speed limit through there. 60mph
