[Code of Federal Regulations] [Title 49, Volume 5] [Revised as of October 1, 2007] From the U.S. Government Printing Office via GPO Access [CITE: 49CFR391.41] [Page 334-335] TITLE 49--TRANSPORTATION DEPARTMENT OF TRANSPORTATION PART 391_QUALIFICATIONS OF DRIVERS AND LONGER COMBINATION VEHICLE (LCV) DRIVER INSTRUCTORS--Table of Contents Subpart E_Physical Qualifications and Examinations Sec. 391.41 Physical qualifications for drivers. (a) A person shall not drive a commercial motor vehicle unless he/ she is physically qualified to do so and, except as provided in Sec. 391.67, has on his/her person the original, or a photographic copy, of a medical examiner's certificate that he/she is physically qualified to drive a commercial motor vehicle. --------------------------------------------------------------------------- The United States and Canada entered into a Reciprocity Agreement, effective March 30, 1999, recognizing that a Canadian commercial driver's license is proof of medical fitness to drive. Therefore, Canadian commercial motor vehicle (CMV) drivers are no longer required to have in their possession a medical examiner's certificate if the driver has been issued, and possesses, a valid commercial driver's license issued by a Canadian Province or Territory. However, Canadian drivers who are insulin-using diabetics, who have epilepsy, or who are hearing impaired as defined in Sec. 391.41(b)(11) 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. --------------------------------------------------------------------------- [[Page 335]] (b) A person is physically qualified to drive a commercial motor vehicle if that person-- (1) Has no loss of a foot, a leg, a hand, or an arm, or has been granted a skill performance evaluation certificate pursuant to Sec. 391.49; (2) Has no impairment of: (i) A hand or finger which interferes with prehension or power grasping; or (ii) An arm, foot, or leg which interferes with the ability to perform normal tasks associated with operating a commercial motor vehicle; or any other significant limb defect or limitation which interferes with the ability to perform normal tasks associated with operating a commercial motor vehicle; or has been granted a skill performance evaluation certificate pursuant to Sec. 391.49.
