Driver Physical Qualification Standards

Question 6: Is the use of coumadin, an anticoagulant, an automatic disqualification for drivers operating CMVs in interstate commerce?

Guidance: No. Although the Department of Transportation’s 1987 ‘‘Conference on Cardiac Disorders and Commercial Drivers’’ recommended that drivers who are taking anticoagulants not be allowed to drive, the FMCSA has not adopted a rule to that effect. The medical examiner and treating specialist may, but are not required to, accept the Conference recommendations. Therefore, the use of coumadin is not an automatic disqualification, but a factor to be considered in determining the driver’s physical qualification status.
