How often must a CDL holder undergo a medical examination?

A Commercial Driver's License (CDL) holder is required to undergo a medical examination every 24 months. This regulation is in place to ensure that drivers are physically fit to operate large vehicles safely, as they can pose significant risks to themselves and others on the road if their health conditions impede their ability to drive.

The medical examination must be conducted by a certified medical examiner listed on the Federal Motor Carrier Safety Administration (FMCSA) National Registry. The purpose of this examination includes assessing the driver's vision, hearing, blood pressure, and overall physical health, including any potential medical conditions that could affect driving capabilities.

For drivers with certain medical conditions, such as diabetes or high blood pressure, more frequent examinations may be necessary. However, under standard circumstances, adhering to the 24-month requirement helps maintain safety standards across all CDL holders. Therefore, retaining this validity period is essential for improving road safety and compliance with federal regulations.
