Perhaps I can add a little bit of constructive advice in reply to your question, Jimsy. It might also help quell the personal slanging match that seems to have erupted between ward~minter and ***********, in which I am sure you have no interest at all.
Ethel has put it very succinctly. Just a bit of further information (which is all based on procedures in England and Wales, but which I imagine are much the same in Scotland).
The Association of Chief Police Officers� guidelines say that, where the limit is 30mph, a fixed penalty should be offered for speeds up to 50mph and a summons to appear before magistrates considered above that. This means that your son is likely to be asked to appear. Ethel is slightly adrift in her sentencing forecast. Magistrates� sentencing guidelines for speeds in excess of 51mph suggest that (in addition to a fine) either six points or a disqualification of up to 56 days should be imposed. Ethel has correctly pointed out that if your son does accumulate six points his licence will be revoked. Curiously, though, if the justices decide to impose a disqualification, it will not lead to revocation.
As ward-minter suggests, a speed awareness course may be offered (though I�m not sure if this is available in Scotland). However, unless it reduces the points to below six it will not avoid the revocation. This is carried out automatically by the DVLA. There are no exceptions and no right of appeal.
One or two other points that have been made need clarification. You are not responsible for your son�s driving from either a criminal or civil point of view. Even if the car is yours and you have permitted him to drive it as a named driver (and you have not said this is the case) the responsibility for his actions does not shift to you.
Finally, it is probably no more than wishful thinking by naz_nomad, but you cannot be imprisoned for speeding no matter what the speed or
