 If the individual committing the offence does not hold a valid driver's licence the endorsements may be put by until a licence is held.Most endorsements remain valid for four years; some (such as driving under the influence) are recorded on the licence for 11 years because more severe penalties apply to those convicted twice within 10 years of drink or drug driving offences.Twelve points on the licence within three years makes the driver liable to disqualification under the "totting-up" procedure; however this is not automatic and must be decided on by a court of law.
