New Mexico requires different permits depending on whether a truck needs temporary registration or temporary fuel tax compliance. Understanding the difference between a Trip Permit and a Fuel Permit helps carriers stay legal and avoid costly penalties.
New Mexico Trip Permits and Fuel Permits

1. What Is a New Mexico Trip Permit?

A New Mexico Trip Permit allows a commercial vehicle to operate temporarily in the state without New Mexico registration.

Key points:

  • Required for vehicles 26,001 lbs or more

  • Used by out-of-state carriers

  • Covers registration compliance only

  • Valid for a limited number of days (typically short-term)

  • Does NOT cover fuel tax obligations

Common use:
An out-of-state truck without IRP registration entering New Mexico for a short haul.


2. What Is a New Mexico Fuel Permit?

A New Mexico Fuel Permit allows a vehicle to operate temporarily without IFTA registration.

Key points:

  • Required if the vehicle is not registered under IFTA

  • Covers fuel tax reporting

  • Short-term validity

  • Does NOT replace vehicle registration

  • Required regardless of vehicle registration status if IFTA is missing

Common use:
A carrier with proper registration but no IFTA account entering New Mexico.


3. Key Differences at a Glance

Feature Trip Permit Fuel Permit
Purpose Registration compliance Fuel tax compliance
Replaces IRP? Yes (temporarily) No
Replaces IFTA? No Yes (temporarily)

4. When Do You Need Both Permits?

You may need both a Trip Permit and a Fuel Permit if:

  • Your vehicle is not IRP registered

  • AND your company is not IFTA registered

Failing to obtain both can result in fines or being placed out of service at New Mexico ports of entry.


5. Enforcement at New Mexico Ports of Entry

New Mexico strictly enforces permit compliance at:

  • Ports of entry

  • Weigh stations

  • Roadside inspections

Inspectors commonly check:

  • Trip permit validity

  • Fuel permit or IFTA credentials

  • Vehicle weight and registration


6. Common Mistakes to Avoid

 Assuming a trip permit covers fuel taxes
 Entering New Mexico with no permits
 Using an expired or incorrect permit
 Confusing IRP with IFTA requirements


7. Best Practice for Carriers

 Verify IRP and IFTA status before entry
 Obtain required permits before crossing state lines
 Keep permits accessible in the vehicle
 Use a permit service if unsure


Final Takeaway

  • Trip Permit = Temporary registration

  • Fuel Permit = Temporary fuel tax compliance

  • They serve different purposes and do not replace each other

Understanding this distinction helps carriers operate legally in New Mexico and avoid unnecessary delays or penalties.
