I don't think you'll be off for 12 months, although it depends to an extent on whether you've got "form". Probably only six weeks or less if your licence is otherwise clean and unendorsed. If you represent yourself, take note of whether the officer adduces evidence to show (1) what the correct conditions for the operation of the machine are, (2) under what conditions the machine was being operated at the time of the alleged offence, and thus (3) that the machine was being used under the correct operating conditions.

If the officer does not give this evidence, the prosecution against you cannot succeed (the information is required under a certain RTA regulation, I can't remember which).

But if you get off on that one, you'll get a pull from the law at every turn for about six weeks!!

Otherwise, good luck.
