A person meeting the definition of farm vehicle driver who operates a straight truck does not require a medical card. A person meeting the definition of a “covered farm vehicle” in intrastate commerce or within a 150 air mile radius in interstate commerce does not need a medical card. If the articulated farm vehicle does not meet the definition of a “covered farm vehicle” or is outside of the 150 air mile radius in interstate commerce, then a medical card would be required.
Note: Custom harvest operations do not meet the farm vehicle driver definitions, but custom harvest vehicle drivers are exempt from the medical card requirements when transporting machinery, supplies, crops, etc. For additional information on medical cards, visit the USDOT website.
