The DMV may ____________ a school bus driver's certificate after dismissal of any driver for a cause related to pupil transportation safety.

The correct answer is that the DMV may suspend a school bus driver's certificate after any driver is dismissed for a cause related to pupil transportation safety. This is crucial because pupil safety is the top priority when it comes to operating a school bus. If a driver is dismissed due to safety concerns, it indicates that their actions may pose a risk to the children they transport.

Suspension serves as a necessary measure to ensure that only qualified and safe drivers are allowed to operate school buses. It also allows for a thorough investigation into the circumstances surrounding the dismissal, providing an opportunity to assess whether the driver can be reinstated or if additional actions are warranted.

In contrast, extending a certificate would imply granting more time to a potentially unsafe driver, while reinstating implies returning a driver to active duty despite unresolved safety concerns. Issuing a certificate would pertain to new applicants rather than dealing with the consequences of safety-related dismissals. The emphasis on suspension reflects the DMV's commitment to enforcing safety standards and protecting students.
