Under Federal Motor Carrier Safety Regulations, which documents are required for a commercial motor vehicle with a combined weight of 10,001 pounds or more?

• A. Proof of insurance and medical card
• B. Vehicle registration and logbook
• C. Logbook and driver's license
• D. Medical card and valid driver's license

Answer: (D)

For a commercial motor vehicle over 10,001 pounds, you must show evidence of medical fitness and legal driving authority. The medical card is the Medical Examiner’s Certificate that proves you meet FMCSA medical standards to operate a CMV. The valid driver’s license confirms you’re authorized to drive, and it should be the appropriate class (and endorsements if the vehicle requires them).

Other documents like a logbook relate to hours-of-service and may be required in certain operations, while proof of insurance and vehicle registration are important for the vehicle and carrier, but they are not the two basic documents you must carry to prove fitness and authorization to operate a CMV.
