Average speed cameras start at m4 J28 with a 50mph and finish at J24 the Coldra, that's as far as I can help mate sorry
Hopefully you arn't going to buy anything in Fowlers. overpriced money grasping b*st*rds
average speed cameras..... on a bike? you got a front plate have you
be carefull if you go on the A38, plenty of cameras and there are quite of then vans as well
watch out for camera/van/car on the bridge over the severn tolls, van there this morning. these are sometimes backed up with patrol cars. They also sit on the bridge at caldicot services with patrol car support (J23a). unmarked cars between caldicot services and tunnels. Oh... and also bridge and slip road east bound at J25. sometimes tax stinger operations too with all units under the bridge on the roundabout at J22other than that pretty clear
