School Transportation - As introduced, extends the use of service of a conventional and Class D school bus from 200,000 miles to 230,000 miles. - Amends TCA Title 49, Chapter 6 and Title 55.

SB 656 amends Tennessee law to increase the maximum mileage limit for conventional and Class D school buses from 200,000 miles to 230,000 miles, specifically updating Tennessee Code Annotated Sections 49-6-2109(b)(2) and relevant provisions in Title 55. This change directly affects school bus operators and transportation departments in Tennessee by extending the allowable operational lifespan of qualifying school buses. The bill modifies a technical mileage standard without altering safety requirements or operational procedures. It does not impose new costs or requirements but adjusts an existing maintenance threshold. The legislation is currently under review by the Senate Education Committee.
