What can happen if a driver accumulates demerit points while on probation?

Accumulating demerit points while on probation can lead to immediate suspension or increased penalties for the driver. In Ontario, when a driver is on probation, it means that they are under a period of observation following a previous infraction or suspension. The probationary period typically comes with stricter scrutiny regarding the driver’s behavior on the road.

If a driver receives additional demerit points during this time, it indicates a pattern of unsafe driving behavior, which triggers an immediate response from the licensing authorities. This can result in a suspension of the driver's license, reflecting the seriousness with which the system treats repeated violations within a probationary status. Furthermore, penalties may be increased because the driver is already in a vulnerable position by being on probation, so the consequences of further infractions are heightened.

The other options do not accurately represent the consequences of accumulating demerit points during probation. Increased fines alone would not encompass the gravity of the situation, as immediate suspension reflects a more severe approach taken to ensure road safety. Mandatory driving assessments and extended probation duration could also be potential outcomes, but they are not as immediate or as certain as suspension. Thus, the correct option highlights the serious implications of driving behavior during a period of probation.
