From what you say, harriman, you might have a good case to plead "special reasons". As I mentioned earlier, the need to drive for work or to transport children is usually (though not always) insufficient to succeed by itself. However, the additional voluntary work you undertake with children may well sway the justices.
The decision is entirely theirs and they must base it on what they hear on the day. As I said earlier, a solicitor is ideally needed to put your case to the bench. Her or his expertise will be almost essential. Also, of course, many people are traumatised enough to be up before a court at all. Some find it hard to think clearly enough to confirm their name, let alone construct a convincing legal argument.
Putting this argument before the magistrates will cost you nothing (apart from your solicitor�s fees, which should not be too hefty). It will not jeopardise any discount you receive on your fines (as you still have to plead guilty to the offences). If successful you will escape a ban under the �totting� process but will still have twelve points on your licence. You will also be warned that you cannot use the same �special reasons� argument again to escape disqualification should you commit a further offence which attracts points.
I�m glad you�ve been sensible enough to accept your guilt and show remorse (this is another quality which will endear you to their Worships). I try not to be judgemental on matters such as this. But I cannot always resist (!) and usually have no time for speeding motorists. However I do have a certain sympathy with you concerning the �multiple offences� aspect of this matter � especially the two which were only two minutes apart. Speak to a solicitor about a �Special Reasons� plea and see what they advise.
