How to Renew or Extend a New Mexico Trucking Permit

1. Understand What Kind of Permit You Have

  • Single-trip OS/OW permit: Usually valid for a limited timeframe (e.g., 5 days for oversize loads) according to common permit practices.  

  • Multiple-trip or annual permits: For frequent hauls, these may be issued for longer durations.  

  • Special permits: For example, overweight permits under New Mexico statute may have specific validity (e.g., up to one year). 

Knowing your permit type is key because renewal or extension rules differ.

2. Know When Extensions Are Allowed

According to the Motor Transportation Police Division (MTPD) rules:

  • The expiration date of a permit may be extended due to inclement weather, road closures, or mechanical breakdowns.

  • However, this is not automatic: extensions require supervisory approval. 

  • If a permit is voided (for instance, for a violation), you may need to apply for a new permit rather than just extending. 

3. How to Request an Extension

Here are the practical steps to request a permit extension:

  1. Contact the Permit Office

    • Reach out to New Mexico’s permit office  (505) 578-2195

    • Use the contact info on your permit paperwork, or call the NMDOT / MTPD permit office.

  2. Provide Necessary Documentation

    • Explain the reason for the requested extension (weather, breakdown, road closure).

    • Supply any relevant proof, such as a breakdown report, repair invoice, or weather advisory.

    • Include your permit number, route details, and original permit expiration date.

  3. Submit the Request in Writing (if Required)

    • Some offices may ask for a written extension request (email or formal letter), especially for formal supervisory review.

    • Keep a documented trail: send your request via email or fax, and ask for confirmation.

  4. Wait for Approval

    • The supervisory unit reviews and either approves or denies the extension based on your justification.

    • If approved, you’ll likely get a written amendment or a revised permit with a new expiration date.

  5. Carry the Updated Permit

    • Once extended, make sure to carry the updated permit document (electronic or hard copy) in your vehicle.

    • Ensure the driver, pilot cars / escort vehicles, and other relevant personnel have the updated permit terms (dates, route, conditions).

4. For Annual or Multiple-Trip Permits: Renewal Process

If you have a permit that’s annual or multiple-trip:

  • Check with the issuing agency (MTPD or NMDOT) about when renewal applications open.

  • Maintain good records: mileage, load data, and compliance history can help with renewal.

  • File any required paperwork or permit renewal application well before expiration, to avoid downtime.

  • Pay any renewal fees that apply.

5. Be Aware of the New Electronic Permitting System

  • New online permitting system - www.newmexicotruckingonline.com

  • Or call to (505) 578-2195

6. Common Pitfalls & Tips

  • Don’t wait until the last minute: As soon as you foresee a delay, start your extension request.

  • Use clear justification: Weather and mechanical issues are valid, but you’ll need to document them.

  • Know the phone numbers: The NMDOT Ports of Entry office can help; their permit contact is listed. 

  • Keep backup documentation: Proof of breakdown or road closure strengthens your case.

  • Stay compliant with route restrictions: Even with extension, you must follow the originally permitted route and conditions.
