Logging and Forestry Oversize Permits

Dec. 8, 2025, 8:25 p.m.
Transporting logs, timber, and forestry equipment often requires oversize permits in New Mexico due to the size, weight, and nature of the loads. The state has specific regulations designed to support the forestry industry while maintaining safety on highways and protecting infrastructure.

1. Purpose of Logging & Forestry Oversize Permits

These permits allow carriers to legally move:

  • Raw logs or timber

  • Logging machinery such as skidders, feller bunchers, harvesters, loaders

  • Forestry support equipment

  • Non-divisible loads that exceed legal size or weight limits

Because forestry operations are frequently located in remote areas, these permits ensure safe transport from harvest sites to mills or processing centers.

2. When a Permit Is Required

A logging or forestry permit is required when the vehicle or load exceeds New Mexico’s legal limits:

Legal dimensions (general):

  • Width: 8’6”

  • Height: 14’

  • Length: varies by vehicle type (e.g., 65’ for some combinations)

Weight thresholds:

  • 80,000 lbs gross vehicle weight

  • Axle and bridge limits depending on configuration

If a log haul or forest machine exceeds any of these limits, an oversize/overweight (OS/OW) permit is required.

3. Types of Applicable Permits

Forestry operations may use several permit types:

A. Single-Trip OS/OW Permits

For one-time moves of large machinery or extra-heavy equipment.

B. Annual Oversize Permits

For carriers who frequently haul the same type of forestry loads.

C. Agricultural & Specialty Permits

Some forestry products may qualify under specific commodity-based permits.

D. Route-Specific Permits

Certain forest roads or mountain passes require special routing due to grades, curves, or restricted bridges.

4. Special Rules for Logging Equipment Transport

New Mexico enforces additional safety and operational rules:

  • Escort (pilot cars) may be required for wide or tall equipment

  • Flags and lighting are mandatory when logs extend beyond the vehicle

  • Load securement must meet FMCSA standards (extra chains/straps for logs)

  • Speed restrictions may apply on steep or winding mountain routes

  • Daylight-only travel for larger oversize loads

Log trucks running with extended loads must also display OVERSIZE LOAD signs.

5. Route Planning Requirements

Logging hauls often involve:

  • Steep grades

  • Unpaved access roads

  • Remote harvest sites

  • Narrow bridges

  • Mountain passes

New Mexico may require:

  • Pre-approved routing

  • Avoidance of weight-restricted bridges

  • Notification of certain state or local authorities

Some forestry corridors are approved specifically for log transport and may offer more flexibility.

6. Permit Fees

Permit fees vary depending on:

  • Size and weight of the load

  • Whether it’s single-trip or annual

  • Route distance

  • Escort requirements

Heavy machinery moves cost more due to weight and complexity.

7. Enforcement and Compliance

New Mexico’s Ports of Entry (POE) enforce trucking permits aggressively. Carriers can expect:

  • Weight checks

  • Dimension verification

  • Load securement inspections

  • Permit audits

Operating without a required permit can result in:

  • Significant fines

  • Delays

  • Vehicle impoundment until compliance is achieved

8. Tips for Logging Carriers

To stay compliant:

  • Measure machinery and log loads carefully

  • Secure loads properly (logs require special binding rules)

  • Check wind advisories—large forestry equipment can be affected

  • Maintain brake and tire condition for mountain hauling

  • Keep permits accessible at all times

Summary

Logging and forestry oversize permits are essential for safely and legally transporting timber and heavy logging equipment in New Mexico. Carriers must follow state-specific rules on size, weight, securement, routes, and travel times to ensure compliance and avoid costly penalties.
