Any interstate fuel user, who is not the holder of a valid interstate fuel user license or operating under the authority of an interstate compact or reciprocal agreement shall, before entering this state, obtain a temporary single-trip permit from the department or any agents appointed by the secretary for issuance of these permits. Temporary single-trip permits shall cost twenty dollars each. The permit is for one trip into or through the state and automatically expires as soon as the vehicle leaves this state. This permit does not allow the holder to purchase fuel on a tax-unpaid basis from any source within this state. The permit fee is in lieu of any other fuel permit fees.
