Driver Licenses - As enacted, removes present law that prohibits a person from being denied a commercial driver license, or being deemed medically unqualified to operate a motor vehicle, based on the failure to meet motor safety carrier regulations because of a medical history or clinical diagnosis of diabetes mellitus currently requiring insulin, but whose medical history indicates that the insulin controls the diabetes to the extent that the condition is not likely to cause any loss of ability to control a motor vehicle. - Amends TCA Title 55, Chapter 50, Part 4.

HB 1546 (Tennessee Code Annotated §55-50-411) removes state restrictions on commercial driver licenses for individuals with certain medical conditions, provided they hold a federal certification. It directly affects commercial drivers who have been certified as medically qualified by a federally certified medical examiner listed in the national registry (per 49 CFR 391.43). The bill amends state law to exempt these drivers from existing intrastate restrictions, aligning Tennessee rules with federal medical certification standards. This change applies only to drivers with valid federal medical certifications, not all drivers with medical conditions.
