Which of the following can be a consequence of failing to complete Traffic Violator School?

Failing to complete Traffic Violator School can indeed result in the retention of points on your driving record, which is the correct consequence to note. When a driver receives a ticket and opts to attend Traffic Violator School, the completion of the course typically leads to the dismissal of the ticket and avoids the addition of points. However, if the driver fails to complete the course, the original penalty applies, including the points that would be assessed on their record for that violation. This can lead to increased insurance premiums and may result in further legal repercussions if the driver accumulates too many points.

The other potential consequences listed do not apply when the course is not completed. For instance, insurance rates are often reduced when traffic violations are dismissed after completing the course; not completing it does not lead to such reductions. Additionally, failing to finish the course would not make a driver eligible for future traffic courses at any advantageous level, nor would it lead to the complete dismissal of the ticket, which is contingent on successful course completion. Thus, the retention of points is a direct and serious consequence of not fulfilling the requirements of Traffic Violator School.
