In order to ensure that commercial and private drivers are medically fit to operate a vehicle, most jurisdictions require a driver’s license medical assessment. For commercial drivers, this assessment is typically performed on an annual basis. For private drivers with certain health conditions, the frequency of the assessment depends on the jurisdiction but is typically every two to five years. For drivers over the age of 75, many jurisdictions require an annual assessment. The driver’s license medical assessment typically includes a physical examination, vision test, and hearing test. In some cases, a urine or blood test may also be required. The purpose of the assessment is to ensure that the driver is physically and mentally able to operate a vehicle safely.
