Early hours Monday morn--in a rush, little other traffic and doing 55mph? on a dual carriageway 40zone, crossing junction.--There was a quick succession of blue flashes as though being tailed by a speed car. What was that? A speed trap or maybe an out of view ambulance. (I hope!) 45 mins later near stockport in a 30 zone doing 40-45. Two quick white flashes but couldn't see any 'flash spot' or bulbs. S--t--more stress waiting for postman. What percentage of these 'flashes' result in fines and points. Good info much appreciated--ta--sc16!
