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.

SB 1669 removes state restrictions on commercial driver license (CDL) holders with certain medical conditions, provided they are certified as medically qualified by a federally certified medical examiner. The bill directly affects commercial drivers who meet federal medical standards (per 49 CFR 391.43) and hold a valid certification from a medical examiner listed on the national registry. It amends Tennessee law to ensure state regulations do not override federal medical qualifications for these drivers. This change allows qualified drivers to operate commercial vehicles without additional state-imposed medical restrictions.
