What should be noted about a driver's response if they show uncertainty in their answers?

When a driver exhibits uncertainty in their answers during a DOT physical examination, it is crucial to document this behavior accurately. Adding comments below their responses provides context for the uncertainties expressed. This documentation helps ensure that any potential health issues or concerns are appropriately followed up on and allows for a more comprehensive understanding of the driver’s fitness for duty.

While passing certificates or disregarding responses may overlook significant health concerns, and immediate marking of responses as incorrect does not provide a complete picture of the driver's capabilities, detailed comments ensure that examiners can convey important nuances regarding the driver's understanding and confidence levels. Recording these observations contributes to better decision-making regarding the driver's medical qualifications.
