All these suspensions had me thinking as well so I jumped on to the RTA website to check mine, I have had 2 fines over the past 4 years, being in Oct 2005 and March 2006,(both 3 point offenses), so I thought I would be on 3 points, not so it would seem as according to the RTA website I'm on 6 still.
I looked into it a bit further and found this.....
Demerit points and licence suspensions
The law requires the RTA to send a notice of suspension to a licence holder who has incurred 12 or more demerit points in any three-year period.
The law permits the counting of demerit points for offences of any age but suspension can only be applied if the dates the offences were committed are within 3 years of each other.
However, the RTA considers it would be unreasonable to consider offences more than 40 months. The 40-month period exists to ensure that delays between an infringement taking place and the RTA being notified of the infringement are taken into account and ensures that only recent and relevant offences are counted.
For this reason, demerit points up to 40 months old are displayed on the RTA’s online demerit point enquiry screen, because these offences have the potential to count towards a demerit point licence suspension.
Demerit points used towards a licence suspension can’t be counted towards future licence suspensions.
Note: Offences and the relevant number of demerit points remain on a person’s driving record irrespective of the age of the offence. If you obtain a copy of your driving record, all your offences and demerit points will be displayed because this accurately reflects your driving history.
So if it's 40 months thats 3 years & 4 months, NOT the 3 years that everyone seems to think it is, am I reading that correct?
