When should an exam be marked as "incomplete examination"?

An examination should be marked as "incomplete examination" when the driver leaves before the examination is fully completed. In this scenario, the absence of the driver indicates that the necessary assessments, tests, or evaluations could not be performed entirely. Properly documenting this situation is crucial for maintaining accurate medical records and ensuring that any necessary follow-up actions can be planned.

When the driver exits the examination prematurely, it creates challenges in making a comprehensive assessment of the individual's medical fitness for duty. Each component of the examination is vital for establishing the driver's eligibility, and incomplete examinations can lead to gaps in necessary medical evaluations. Thus, marking the exam as incomplete ensures that both the examiner and the driver are aware of the need for further evaluation to fulfill the certification process.

While the other options may reflect situations that warrant additional actions or follow-up, they do not imply a state of incompleteness in the examination itself in the same way that a driver's premature departure does.
