Violation rate is the percentage of points that an operator has accumulated against the set maximum thresholds. The threshold is the allowable rate, expressed in a percentage, that the operator may reach.
An operator’s threshold is the maximum violation rate deemed acceptable for that specific operator. The violation-rate threshold is not the same for all operators. It is calculated based on the number of vehicles and drivers in the operator’s fleet and the number of kilometres travelled. (For example, an operator with more vehicles and travelling a farther distance would have a higher threshold then a small operator.)
Violation rates are accumulated based on an operator’s collision, convictions and inspections over, and up to, a 24-month sliding period. All events are given a point value, and if the operator exceeds their violation-rate threshold, intervention and sanctions will be applied in a progressive action. (For example, an operator that exceeds 35 percent of their allowable threshold may be subject to a warning letter.)
The CVOR system calculates the operator's violation rates for collisions and convictions based on the total number of points accumulated over, and up to, a 24-month sliding period, compared to the threshold values established for that operator's kilometric rate of travel during that same period. For inspections, the total points accumulated in any given period, up to a maximum of 24 months, are compared with the threshold points established based on the number of units (drivers and vehicles) inspected during that same period These individual thresholds are combined to arrive at an overall violation rate with collisions and convictions weighted double to inspections.
As new events and points are recorded, those older than 24 months drop off. The formula is based on a 24-month period or the number of months since the start of the operator's CVOR record, whichever is less. The violation rate is converted to a percentage of the operator's threshold. Appropriate ministry interventions and sanctions are triggered by the CVOR system if an operator reaches various levels of its threshold.
Note: For details of the threshold-value tables, threshold formulas and sample calculations of kilometric rate of travel, violation rates and percentages of threshold calculations of how you arrive at your violation rate, see Appendix A.
The Deputy Registrar may authorize appropriate interventions and sanctions in cases not triggered by the automated system.
