Colorado CDL Practice Test 2025 – Complete Exam Prep

The requirement for CDL holders to undergo medical examinations is every two years. This two-year interval is stipulated by the Federal Motor Carrier Safety Administration (FMCSA) to ensure that commercial drivers maintain the necessary health standards to operate large vehicles safely. A comprehensive medical examination assesses various health factors, including vision, hearing, and the overall physical and mental condition of the driver.

Staying compliant with this two-year requirement is crucial as it helps to reduce the risk of accidents due to medical issues while driving commercial vehicles. Regular medical checks ensure that any potential health concerns are identified and managed appropriately, promoting the safety of all road users.
