Car tags; clarify privilege tax not paid on $1 tags for certain veterans with service-connected disabilities.

SB 2864 clarifies that Mississippi veterans rated with a 100% permanent or 70% nonpermanent service-connected disability by the VA are exempt from the highway privilege tax when using $1 license tags for vehicles or motorcycles. It directly affects qualifying veterans (and their surviving spouses) who receive these tags, specifying they pay only $1 annually without additional tax. The bill updates existing law to explicitly state this tax exemption and requires nonpermanent disability holders to provide updated VA documentation for tag renewals. It does not change the $1 tag cost but ensures the tax exemption is legally clear in the tax code.
