Correct. The licence will be suspended.
A lot of ppl mistakenly believe that as long as they have not hit 24 demerit points 2 years after their first offence, their total points will automatically be erased and reset to zero.
So, in the test question example, some may think that after 5 Jan 2012 which is 24 months after the first offence, the total 22 points accumulated would be reset to zero. Wrong. Because from 10 Dec 2010 until 5 Mar 2012, which is less than 24 months, the offender already accumulated 24 points.
But you rightly pointed out that there is an incentive. If you do not get any demerit points within any consecutive 12 month period, all your previous points will be erased and you start from zero again.
So, no need to wait 24 months. As long as for the next 12 months, no demerit points, then all previous points are erased.
