The Federal Motor Carrier Safety Administration (FMCSA) recently released a final rule revising federal regulations allowing individuals with a stable insulin regimen and properly controlled insulin-treated diabetes mellitus (ITDM) to be qualified to operate commercial motor vehicles (CMVs) in interstate commerce. These individuals previously were prohibited from operating CMVs in interstate commerce without obtaining an exemption from FMCSA. Under the rule, a certified medical examiner can grant an individual with ITDM a Medical Examiner's Certificate, MCSA-5876, for up to 12 months. This requires the treating clinician to provide the certified medical examiner with an ITDM Assessment Form, MCSA-5870, indicating that the individual maintains a stable insulin regimen and proper control of their diabetes. Then, the certified medical examiner must determine whether the individual meets the FMCSA's physical qualification standards and can operate CMVs in interstate commerce. The FMCSA said the rule will save the nearly 5,000 individuals with ITDM that currently have exemptions more than $5 million per year more than what they would endure under the exemption program; new ITDM exemption applicants and their associated motor carriers approximately $215,000 annually in opportunity and compliance costs related to the exemption program's waiting period; and the agency more than $1 million per year over the next three years in costs associated with administering the diabetes exemption program.
