What Is a Non-Divisible Load in New Mexico?

A non-divisible load is one that cannot be reasonably dismantled, separated, or reduced to meet legal limits without:

  • Compromising the load’s intended use

  • Damaging the load

  • Requiring more than a reasonable amount of labor or time

Common examples:

  • Construction equipment (excavators, cranes, loaders)

  • Oilfield equipment

  • Large generators or transformers

  • Precast concrete beams

  • Tanks, silos, or oversized machinery

If the load can be broken down into smaller pieces, New Mexico generally will not issue a permit.

 When a Permit Is Required

You need a non-divisible load permit if your vehicle or load exceeds any of New Mexico’s legal limits, such as:

  • Width: Over 8 feet 6 inches

  • Height: Over 14 feet

  • Length: Over legal vehicle or combination limits

  • Weight: Over legal axle, group, or gross weight limits

Permits are required before entering or operating on New Mexico public highways.

 Types of Permits Available

 Single-Trip Permit

  • Valid for one specific move

  • Route-specific

  • Most common option for non-divisible loads

Annual Permit (Limited)

  • Available only for certain equipment and dimensions

  • Not all non-divisible loads qualify

Most oversized or overweight non-divisible loads use single-trip permits.

 Information Needed to Apply

When applying for a New Mexico non-divisible load permit, you’ll typically need:

  • Vehicle and trailer details

  • Exact load dimensions (width, height, length)

  • Gross weight and axle weights

  • Origin and destination

  • Requested route

  • Proof the load is non-divisible

Accuracy is critical—incorrect dimensions can void the permit.

 Escort (Pilot Car) Requirements

Escort requirements depend on the load’s size:

  • Wider loads may require one or more pilot cars

  • Extremely wide or long loads may require law enforcement escort

  • Escort vehicles must meet New Mexico’s safety and signage standards

NMDOT will specify escort requirements on the permit.

 Travel Time & Restrictions

Non-divisible load permits often include restrictions such as:

  • Daylight-only travel

  • No weekend or holiday travel

  • Weather restrictions (wind, visibility)

  • Urban area curfews

These conditions are permit-specific and must be followed exactly.

 Interstate Carriers

Out-of-state carriers:

  • Must obtain New Mexico permits before entering the state

  • Cannot use permits from neighboring states

  • Must comply with New Mexico-specific routing and escort rules

Penalties for Non-Compliance

Operating without the proper permit—or violating permit conditions—can result in:

  • Fines and citations

  • Vehicle out-of-service orders

  • Delays and load impoundment

  • Permit revocation
