Proposes a constitutional amendment that modifies provisions relating to transportation funding

HJR 192 proposes a constitutional amendment to dedicate specific highway-related revenues to a new "state road fund" for transportation projects. It would require that 73% of the state sales tax on motor vehicles, trailers, and related fuels - after deducting collection costs - be deposited directly into this fund, with the remainder distributed to counties, cities, and a separate transportation fund. The fund must be used exclusively for state highway construction, maintenance, bond payments, and reimbursing counties for roads later adopted into the state system. This change would bypass annual legislative appropriations for these purposes, directly affecting Missouri's highway system, county road costs, and the state highways commission's budget authority.
