Yes, Shakeperian, you are absolutely incorrect with your view of points and disqualification.
Any offence with carries an endorsement and a discretionary disqualification (such as speeding) attracts either points or a disqualification. Both cannot be imposed for a single offence. Offences which carry a mandatory disqualification (such as driving with excess alcohol) attract the mandatory disqualification but no points. There is no “points equivalent” for a disqualification. The two are entirely unrelated.
Penalty points are designed to punish by way of a disqualification drivers who commit a series (at least two and at most four) minor offences within three years, where any one of them would not normally attract a disqualification by itself.
I, too, find some aspects of your problem a little hard to understand, DAROW. I cannot imagine how your insurance has not increased. Of course your NCD will not have been affected as you did not make a claim. But as Shakeperian says, almost all policies have increased considerably this year. Declaring an Excess Alcohol conviction will certainly add to that increase. As far as driving on your husband’s policy goes, you must tell me where he got his insurance. Virtually no insurers offer ordinary motorists an “any driver” policy now. They want to know the driving history of anybody who is likely to be driving the vehicles they insure. As far as the details of your conviction go they are not recorded on your driving record. You have a conviction for Excess Alcohol, and that is that.
