In the above areas i have seen on many occasions an unmarked Police car, silver and a blue BMW estate, so far he is not pulling trucks for going over 40 mph on the single or over 50 mph on the duals, so take it easy out there, it is the A303 to the Warminster by pass that seems to be his “patch” at the moment.
He may sit on the roundabout at the road works by the pig farm, or the honkers hotel i call it, where the container lads go towards Salisbury to avoid the low bridge at Wilton.
