A DOT physical is a medical examination required for commercial drivers to ensure they are physically and mentally fit to safely operate a commercial motor vehicle. The exam is conducted by a certified medical examiner and evaluates a driver’s overall health, including vision, hearing, blood pressure, heart health, respiratory function, and general physical condition. During a DOT physical, the examiner also reviews medical history, medications, and checks for conditions that could affect safe driving, such as diabetes or sleep disorders. Successfully completing the exam allows drivers to receive or maintain their commercial driving certification and continue working in roles that require a commercial driver’s license.
