Computation of total number of points

In computing the total number of points levied against any dealer after a particular violation, those accrued as a result of violations during the twelve-month period including and immediately preceding the last violation must be counted at their full value. Those accrued from twelve to twenty-four months preceding the last violation must be counted at one-half their established value, and those resulting from violations which occurred more than twenty-four months prior to the last violation must not be counted.
