The penalty point system is intended to deter drivers and motorcyclists from following unsafe motoring practices. Certain non-motoring offences, e.g. failure to rectify vehicle defects, can also attract penalty points.
The court MUST order points to be endorsed on the licence according to the fixed number or the range set by Parliament. The accumulation of penalty points acts as a warning to drivers and motorcyclists that they risk disqualification if further offences are committed.
Law RTOA sects 44 & 45
A driver or motorcyclist who accumulates 12 or more penalty points within a 3-year period MUST be disqualified. This will be for a minimum period of 6 months, or longer if the driver or motorcyclist has previously been disqualified.
Law RTOA sect 35
For every offence which carries penalty points the court has a discretionary power to order the licence holder to be disqualified. This may be for any period the court thinks fit, but will usually be between a week and a few months.
In the case of serious offences, such as dangerous driving and drink-driving, the court MUST order disqualification. The minimum period is 12 months, but for repeat offenders or where the alcohol level is high, it may be longer. For example, a second drink-drive offence in the space of 10 years will result in a minimum of 3 years disqualification.
