49 CFR § 391.51 - General requirements for driver qualification files.
(b) The qualification file for a driver must include:
(3) The certificate of driver's road test issued to the driver pursuant to § 391.31(e), a copy of the license or certificate which the motor carrier accepted as equivalent to the driver's road test pursuant to § 391.33, or the original of the written statement providing that the motor carrier determined the driver is not required by § 391.44(d) to complete a road test pursuant to § 391.44(d)(3)(ii)(A) and the original, or a copy, of the driver's certification required by § 391.44(d)(3)(i);
(ii) For CDL holders, beginning January 30, 2012, if the CDLIS motor vehicle record contains medical certification status information, the motor carrier employer must meet this requirement by obtaining the CDLIS motor vehicle record defined at § 384.105 of this chapter. That record must be obtained from the current licensing State and placed in the driver qualification file. After January 30, 2015, a non-excepted, interstate CDL holder without medical certification status information on the CDLIS motor vehicle record is designated “not-certified” to operate a CMV in interstate commerce. After January 30, 2015, and through June 22, 2025, a motor carrier may use a copy of the driver's current medical examiner's certificate that was submitted to the State for up to 15 days from the date it was issued as proof of medical certification.
(iii) If that driver obtained the medical certification based on having obtained a medical variance from FMCSA, the motor carrier must also include a copy of the medical variance documentation in the driver qualification file in accordance with paragraph (b)(7) of this section;
(7) A Skill Performance Evaluation Certificate issued by FMCSA in accordance with § 391.49; or the Medical Exemption document issued by a Federal medical program in accordance with part 381 of this chapter; and
(ii) Through June 22, 2025, for drivers required to have a CDL, a note relating to verification of medical examiner listing on the National Registry of Certified Medical Examiners required by § 391.23(m)(2).
(d) The following records may be removed from a driver's qualification file three years after the date of execution:
(4) Any medical variance issued by FMCSA, including a Skill Performance Evaluation Certificate issued in accordance with § 391.49; or the Medical Exemption letter issued by a Federal medical program in accordance with part 381 of this chapter; and
