Driver's license; prescribe information to be included on and authorize discretionary inclusion of blood type.

HB 539 would allow Mississippi driver's license holders to voluntarily include their blood type on the reverse side of their license, provided they submit medical documentation verifying their blood type at the time of issuance or renewal. This change would directly affect license holders who choose to provide this optional health information. The bill specifies that blood type inclusion would be discretionary - licensees must present medical proof, and it would not be required or automatically included. The measure does not alter existing mandatory license details like name, address, or date of birth. (Note: The bill died in committee in 2026 and was never enacted.)
