March 11, 2026, 5:50 p.m.
A New Mexico Multiple Trip Oversize/Overweight Permit allows commercial motor carriers to transport loads that exceed standard legal size or weight limits across the state multiple times within a specific period. Instead of applying for a separate permit for each trip, carriers can obtain a permit that authorizes repeated movements along approved routes. These permits are issued and regulated by the New Mexico Department of Transportation (NMDOT), which oversees the safe movement of oversize and overweight vehicles on state highways.

Purpose of a Multiple Trip Oversize/Overweight Permit

The main purpose of this permit is to simplify the permitting process for trucking companies that frequently transport similar oversize or overweight loads. By allowing multiple trips under one permit, the state reduces administrative burdens for both carriers and regulators while ensuring compliance with highway safety and infrastructure protection standards.

These permits are commonly used by industries that move heavy or oversized equipment on a regular basis.

When a Multiple Trip Permit Is Used

A multiple trip oversize/overweight permit is typically used when:

  • A company repeatedly transports the same type of oversize or overweight load

  • The vehicle configuration remains consistent

  • The load travels along approved or designated routes within the state

  • You must have active General Liability Insurance On File

  • The carrier expects to make frequent trips during the permit period

This option is especially useful for construction, energy, and infrastructure projects that require repeated equipment transportation.

Common Industries That Use Multiple Trip Permits

Several industries operating in New Mexico regularly rely on multiple trip oversize/overweight permits, including:

  • Construction and heavy equipment transport

  • Oil and gas operations

  • Wind energy and renewable energy projects

  • Agricultural machinery transportation

  • Industrial manufacturing and logistics

These industries often need to move large equipment multiple times during a project, making a multiple trip permit more efficient than obtaining individual permits.

Size and Weight Considerations

Vehicles that exceed legal limits for width, height, length, or weight typically require oversize/overweight permits.

The permit covers up to following dimensions - 

 

Loaded width- up to 14 feet

Loaded height- up to 15 feet

Loaded length - up to 120 feet

Loaded Front Overhang - up to 15 feet

Loaded Rear Overhang - up to 25 feet

Grossweight- up to 140,000 pounds, with the legal weight distribution on axles.

 

Carriers must ensure their vehicles meet all safety requirements, including:

  • Proper load securement

  • Required signage and warning flags

  • Escort vehicles when necessary

  • Approved travel times and routes

Benefits of a Multiple Trip Permit

Obtaining a multiple trip oversize/overweight permit offers several advantages for trucking companies:

  • Reduces the need for repeated permit applications

  • Saves time for carriers that make frequent trips

  • Streamlines compliance with state transportation regulations

  • Improves operational efficiency for recurring oversize shipments

For businesses moving heavy equipment or large loads regularly, this type of permit can significantly simplify logistics operations.

Summary

A New Mexico Multiple Trip Oversize/Overweight Permit allows motor carriers to transport oversize or overweight loads multiple times under a single permit authorization. Issued by the New Mexico Department of Transportation, this permit helps trucking companies streamline operations while maintaining compliance with state transportation and safety regulations.
