For Mexican drivers, the medical examination is part of the Licencia Federal. It is not necessary for Mexican drivers to carry a separate medical certifying document.

A CMV operator from Canada or Mexico who has been issued a valid commercial driver’s license by a Canadian Province or the Mexican Licencia Federal is no longer required to have a medical certificate. The driver’s medical exam is part of the driver’s license process and is proof of medical fitness to drive in the United States. However, Canadian and Mexican drivers who have epilepsy or who are hearing-and-vision impaired are not qualified to drive CMVs in the United States. Furthermore, Canadian drivers who do not meet the medical fitness provisions of the Canadian National Safety Code for Motor Carriers but who have been issued a waiver by one of the Canadian Provinces or Territories are not qualified to drive CMVs in the United States. Similarly, Mexican drivers who do not meet the medical fitness provision of The Licencia Federal de Conductor but who have been issued a waiver by The Licencia Federal de Conductor are not qualified to drive CMVs in the United States.
