Trucking Permit in New Mexico

1. General Requirement for Trucking Permits

Any commercial vehicle operating on New Mexico highways that exceeds standard legal limits must obtain the proper trucking permit before travel. These limits are established under NMDOT regulations and include restrictions on vehicle weight, size, and axle load.

Even if your business is based out of state, you’ll still need a New Mexico permit if you plan to enter or operate within state boundaries.

2. When a Permit Is Required

You must apply for a New Mexico trucking permit if your vehicle meets any of the following conditions:

  • Exceeds weight limits:

    • Over 80,000 pounds gross vehicle weight, or

    • Exceeds 20,000 pounds on a single axle or 34,000 pounds on a tandem axle.

  • Exceeds size limits:

    • Width over 8 feet 6 inches,

    • Height over 14 feet, or

    • Length exceeding 65 feet for a combination vehicle.

  • Transporting oversize or overweight loads such as heavy machinery, modular homes, or construction equipment.

  • Carrying hazardous materials that require special routing and safety authorization.

  • Operating without IRP or IFTA credentials (for out-of-state carriers), in which case you need a New Mexico temporary trip or fuel permit.

3. Exemptions from Trucking Permits

Not all vehicles require trucking permits. Exemptions often include:

  • Agricultural and farm vehicles operating within local areas during harvest seasons.

  • Government and emergency vehicles performing official duties.

  • Recreational vehicles (RVs) or private non-commercial trucks that don’t exceed size or weight limits.

However, even exempt vehicles may still be subject to inspection or special routing during certain conditions, such as weather-related restrictions.

4. Types of Permits Available

Depending on your needs, the NMDOT offers several types of trucking permits:

  • Single-trip permits – For one-time movements through New Mexico.

  • Annual permits – For frequent carriers operating similar routes.

  • Oversize/Overweight load permits – For vehicles exceeding legal dimensions or weight.

  • Fuel and trip permits – For out-of-state carriers not registered under IFTA or IRP.

5. How to Obtain a Permit

Be prepared to provide:

  • Vehicle and load details,

  • Proof of insurance,

  • USDOT number,

  • Desired routes and travel dates.

6. Why Compliance Matters

Operating without a valid trucking permit can lead to:

  • Fines up to several thousand dollars,

  • Detainment of your vehicle,

  • Delays in delivery schedules,

  • Record violations affecting your USDOT safety score.

Maintaining compliance not only keeps your operations legal but also builds a reliable reputation with shippers and regulators.

Conclusion

If your commercial vehicle exceeds standard weight, size, or operational limits—or if you’re an out-of-state carrier entering New Mexico—you’ll need to secure the appropriate trucking permit before travel. Staying compliant with NMDOT rules ensures smooth operations, avoids penalties, and keeps your business moving efficiently across state lines.
