Motor Vehicles - As introduced, prohibits governmental entities that regulate entertainment transportation from denying the transfer of a permit, establishing certain noise ordinances, requiring an entertainment transportation vehicle to be enclosed, and taking other actions under certain circumstances. - Amends TCA Section 7-51-1008.

SB 2474 prohibits local governments in Tennessee from denying the transfer of entertainment transportation permits (like party buses) between qualified businesses, requiring vehicles to be enclosed if safety standards are met, or imposing stricter noise limits than other tourism-area commercial vehicles. It also bans local authorities from demanding traffic studies as a permit condition and prevents arbitrary permit revocations without "good cause" (like repeated violations or six months of disuse). The bill directly affects businesses operating entertainment transportation services and the local governments that regulate them. It ensures permit transfers can occur when businesses meet state/local qualifications and require notice to authorities, while standardizing noise rules and safety requirements. The law aims to reduce regulatory barriers for this sector under state law.
