State Laws and Regulations

Alternative Fuel Vehicle (AFV) Acquisition and Alternative Fuel Use Requirements

Effective January 1, 2008, at least 70% of new vehicles purchased for the state vehicle fleet must be flexible fuel vehicles that can operate on fuel blends of 85% ethanol (E85). Excess acquisitions of AFVs may be credited towards future biennial goals. If a state agency fails to meet a biennial acquisition goal, purchases of any non-AFVs are not permitted until the goals are met or an exemption or goal reduction has been granted. In addition, 30% of the fuel purchased annually for use in state fleet vehicles must be alternative fuels. (Reference Senate Bill 54, 2007 and Missouri Revised Statutes 414.400 and 414.410)

Alternative Fuel Tax

The $0.17 per gallon motor fuel tax does not apply to passenger motor vehicles, certain buses, or commercial motor vehicles that are powered by an alternative fuel. Instead, the owners or operators of such vehicles are required to pay an annual alternative fuel decal fee as follows (certain restrictions apply):

Gross Vehicle WeightType of VehicleDecal Fee

It is unlawful for any person to operate a motor vehicle required to have an alternative fuel decal upon the highways of this state without a valid decal. No person may fuel alternative fuel vehicles with liquefied petroleum gas (LPG) or natural gas unless the vehicle has a valid decal. (Reference Missouri Revised Statutes 142.803 and 142.869)

Liquefied Petroleum Gas (LPG) License

Persons involved in the retail sale, transport or handling of LPG, or in the business of installing or modifying related equipment must first register with the Director of the Department of Agriculture. (Reference Missouri Revised Statutes 323.060)
