Missouri is the only state still using horsepower to determine vehicle registration fees, but a Senate bill aims to change that along with other fee increases and modernization efforts. Senate Bill 1632, sponsored by Sen. Sandy Crawford, seeks to update the motor vehicle and driver’s licensing system in the state. The bill includes provisions to change how state car registration fees are determined, increase transfer fees, and raise delinquency fees for late renewals. If passed, the bill would bring in additional revenue for highway, city, and county funds and streamline the registration process in Missouri.
