Mississippi sells one 72-hour trip permit, issued by MDOT in place of apportioned IRP plates, to out-of-state trucks over 26,000 pounds that are not registered in Mississippi. Neither MDOT's fee sheet nor the Department of Revenue's pages publish a Mississippi fuel trip permit, so the fuel side is left unconfirmed here.
The trip permit (registration side)
This credential answers for registration. Without it, a vehicle whose cab card does not list Mississippi has no legal registration standing in the state.
- Fee
- $25 ($25.00 per vehicle, per the Department of Revenue IRP manual, MDOT's 2026 permit manual (Single Trip Permit) and MDOT's Permit and Blanket Fees sheet (72 Hour Legal Trip Permit). A load that is also oversize or overweight needs its own oversize or overweight permit on top. Permit services add their own charge.)
- Who needs it
- A non-resident owner-operator of a vehicle over 26,000 pounds gross that has not been registered in Mississippi and has not paid the annual privilege tax. The permit covers state maintained highways and interstates in Mississippi.
- Where to buy
- At the Mississippi scales, paid by credit card; By phone from MDOT at (601) 359-1717 or toll free (888) 737-0061; Through a permit service
The fuel permit (tax side)
This credential answers for the state's highway or fuel tax when there is no IFTA license (or, in the weight-distance states, no tax account) behind the truck.
- Fee
- MDOT's Permit and Blanket Fees sheet lists no fuel permit, the 2026 permit manual describes none, and the Department of Revenue's Interstate Commercial Vehicles page and IRP manual describe none for Mississippi. The Mississippi Code sections that would set a non-IFTA fuel rule could not be read at the official publisher, and the Title 35 Part IX petroleum rules (read in an archived copy after sos.ms.gov returned 403) cover importers, dyed diesel and direct pay permits only. No fee, rule or duration is recorded.
- Valid for
- No Mississippi fuel permit or fuel-purchase rule is published on the MDOT or Department of Revenue pages read, so no validity period exists to record.
- Who needs it
- Qualified vehicles (over 26,000 pounds, or three or more axles) entering Mississippi without an IFTA license. The Department of Revenue's IRP manual says only that a carrier that qualifies for IFTA but does not join must buy fuel permits under each member jurisdiction's own rules; for Mississippi's own rule, ask the Department of Revenue IRP/IFTA office.
Other temporary permits in Mississippi
Short-term credentials Mississippi issues beside the trip and fuel permits, for situations those two do not cover.
Worth knowing
Oversize and overweight permits are a separate MDOT credential bought through ExpressPass (the state permits page). Carriers making regular Mississippi trips register under IRP and license under IFTA with the Department of Revenue instead (the state IRP page, the state IFTA page).
Where these fit in the Mississippi permit stack
Temporary permits are the exception path. The standing credentials they replace are IRP apportioned registration and the Mississippi IFTA license. Oversize loads use a different permit family entirely, covered in Mississippi oversize and overweight permits, and the full picture of every state permit lives in Mississippi trucking permits.
