Establishes a motor fuel tax exemption for certain government-owned vehicles when used for public service purposes

HB 2515 exempts motor fuel used in government-owned vehicles primarily serving public purposes from state fuel tax. It applies to vehicles like fire trucks, ambulances, police cars, and snowplows owned or leased by state/local governments, provided they are used for public service 75% of the time. The bill requires that at least 75% of a vehicle's mileage directly supports essential government functions or public services to qualify for the exemption. This policy change removes a cost burden for qualifying government fleets without altering existing tax rates for private vehicles.
