Fuel tax and apportioned plates are not administered where most people look for them
A new Missouri carrier that goes looking for the state’s motor carrier fuel and registration programmes at the Department of Revenue will not find them. That path was probed on September 3, 2026 and returned a 404, and the statute explains why rather than the website.
RSMo 226.008.1 gives the highways and transportation commission responsibility and authority for, among other things, subdivision (5) “Collecting and regulating amounts payable to the state from interstate motor carriers in accordance with the provisions of the International Fuel Tax Agreement in accordance with section 142.617, and any successor or similar agreements, including the authority to impose and collect motor fuel taxes due pursuant to chapter 142, and such agreement”, and subdivision (6) registering and regulating interstate commercial motor vehicles under the International Registration Plan in accordance with sections 301.271 through 301.277, including the authority to issue license plates. That section is stamped effective August 28, 2014. The same transfer is printed as a cross reference under RSMo 142.617 and again under RSMo 301.271, both read September 3, 2026.
The threshold for fuel-tax licensing is not Missouri’s to write, and reading it at the agreement rather than at a summary is the point of the exercise. R245 of the IFTA Articles of Agreement builds its Qualified Motor Vehicle out of a preamble, three numbered limbs and one closing exclusion, and separating them shows why a summary usually gets it wrong. The preamble asks whether the vehicle is used, designed, or maintained for the transportation of persons or property. Limb .100 then reaches a two-axle unit above 26,000 pounds gross or registered gross weight, a figure the Articles also print in metric. Limb .300 reaches a unit run in combination once the combination passes the same weight.
Limb .200 is the short one and the one that reaches small operations: “Having three or more axles regardless of weight”. No floor sits under it. A light three-axle power unit satisfies R245 where a two-axle unit at the identical weight does not, and the difference is a count rather than a scale reading.
Then comes the sentence that restatements drop, and it is part of the definition rather than a note attached to it: “Qualified Motor Vehicle does not include recreational vehicles.”
Qualifying does not by itself create a license duty. R305 supplies that: any person based in a member jurisdiction operating a qualified motor vehicle in two or more member jurisdictions is required to license under the Agreement, except as indicated in R310 and R500. R310 is the alternative worth knowing in a first year — “In lieu of motor fuel tax licensing under this Agreement, persons may elect to satisfy motor fuels use tax obligations on a trip-by-trip basis.” The Articles were read in the revision dated 03-11-2026 on September 3, 2026. The parallel apportionable-vehicle threshold under the International Registration Plan was not read at its own source this run and no figure for it is stated here.
