Who is required to be medically qualified (possess a DOT medical card) to operate a Commercial Motor Vehicle in interstate and intrastate commerce?
ALL drivers that have a Class A, B or C CDL must be medically qualified (possess a DOT medical card) to operate a CMV.
Interstate drivers are required to present the medical card to the Department of Public Safety when obtaining or renewing a CDL.
Intrastate drivers are not required to present the DOT medical cards when obtaining or renewing a CDL BUT will get a "K" restriction put on the CDL. These drivers are still required to have a valid DOT medical card on their person.
Government employees are exempt from the DOT medical card requirement.
