Some points about this. Firstly, If you get any 'notice of intended prosecution' within two weeks of being 'flashed' then straight away write in response asking for copies of the evidence. Also, by law you have to complete the declaration of who was driving the vehicle but DO NOT under any circumstances sign it. By putting the drivers name and address on the form you are complying with the law, but there is NO legal requirement to sign it. By not signing it, it is not admissable in court as evidence. If you were 'flashed' three times in succession over a period of a few minutes then it sounds like you were driving at 35 mph for a period of time past three cameras. The offence is not 'going fast past a speed camera' but one of 'going fast'. If you only did this once, and it was observed by cameras three times, then you only actually committed the speeding offence once. There are just three pieces of evidence to that ONE offence, not three offences. This will need carefully putting in court, but should result in just the usual sixty quid fine plus three points. Of course, if you were caught three times by the same camera in quick succession, by repeating the same short journey thre times, then you really should have taken the first flash more seriously. As regards misbehaving children, well, no excuse I'm afraid. As the driver it is up to you to make sure that your passengers behave and do not distract you. I would suggest you try discipline. The correct level of discipline is just enough to stop the misbehaviour.
