How short of a period can a medical examiner put on the certification card?

The certification card issued by a medical examiner can indeed reflect a shorter period based on the specific medical circumstances of the individual being evaluated. Medical examiners have the discretion to determine the length of the certification based on the driver's health status, compliance with medical treatment, or ongoing monitoring needs.

This flexibility allows medical examiners to promote safety by ensuring that drivers who may have temporary medical issues or conditions that could affect their ability to drive safely are monitored closely. By being able to issue a certification for as short a period as desired, the medical examiner emphasizes the importance of continuous health assessment, ensuring that drivers remain medically fit to operate commercial vehicles.
