The FMCSA announced on July 14 an exemption to the new NRII rule to facilitate the transition.
On June 23, the U.S. Department of Transportation (DOT), through the Federal Motor Carrier Safety Administration (FMCSA), officially implemented a new regulation that transforms the medical certification process for commercial driver’s license (CDL) holders. This regulation, known as the Medical Examiner’s Certification Integration Rule (NRII), fully digitizes the system, eliminating the use of paper medical certificates.
However, as a temporary regulatory relief measure, the FMCSA announced on July 14 an exemption to facilitate the transition. During this period, interstate CDL holders, commercial learner’s permit (CLP) holders, and motor carriers will be allowed to continue using printed copies of the Medical Examiner’s Certificate (MEC) as valid proof of medical certification. This measure will be valid for up to 15 days after the date the medical certificate is issued.

FMCSA grants exemption for NRII
The FMCSA stated that this exemption will remain in effect only until October 12, 2025. After that date, the transition to the digital system will be fully completed. Additionally, the agency recommended that medical examiners continue providing drivers with a paper copy of the medical certificate, in addition to submitting results electronically.
As of July 14, only 38 states and the District of Columbia had fully implemented the NRII. The remaining 12 states still rely on paper MECs, according to the FMCSA. This disparity prompted officials to issue the exemption to ease the process for both medical examiners and drivers.
“It is in the public interest to issue an exemption so that drivers with valid medical certification and their employers are not negatively impacted by delays beyond their control during the transition to NRII,” the agency stated.
The exemption issued by the FMCSA includes the following restrictions:
- The exemption does not apply to a driver who does not have a current and valid copy of their MEC issued by a medical examiner within the previous 15 days.
- Does not apply to motor carriers that do not have a current and valid copy of the driver’s MEC issued by a medical examiner within the previous 15 days.
- The FMCSA reserves the right to revoke this exemption if it results in a lower level of safety than was maintained prior to its issuance, or if continuing the exemption is inconsistent with the goals and objectives of 49 USC 31136(e) and 31315(a).

NRII rule: reducing fraud and streamlining processes
The NRII rule requires medical examiners to electronically transmit all results of physical examinations conducted for CDL or CLP applicants directly to the FMCSA’s National Registry. It also mandates that examiners submit these results by midnight of the next calendar day following the examination.
According to FMCSA officials, the purpose of this update is to reduce fraud and streamline bureaucracy for drivers by enabling real-time access to a driver’s medical certification status during roadside inspections.
