A New Mexico Overweight or Oversize Permit Bond is a surety bond required by the New Mexico Department of Transportation (NMDOT) for certain carriers hauling loads that exceed the state’s legal size or weight limits. The bond guarantees that the carrier will comply with permit conditions and pay for any damage caused to New Mexico roads, bridges, or infrastructure.

Why New Mexico Requires This Bond

When vehicles operate over legal weight or dimension limits, they pose a higher risk of damaging public infrastructure. New Mexico requires this bond to:

  • Protect state highways and bridges

  • Ensure carriers follow permit rules and approved routes

  • Provide financial coverage if damage occurs

The bond serves as a financial guarantee, not insurance.

Who Needs an Overweight or Oversize Permit Bond

You may be required to obtain this bond if you:

  • Haul overweight loads exceeding legal axle or gross weight limits

  • Transport oversize loads exceeding width, height, or length limits

  • Move specialized or heavy equipment under a state-issued permit

  • Are specifically required by NMDOT to post a bond for certain permits

Both in-state and out-of-state carriers may be required to file the bond.

How the Bond Works

The bond involves three parties:

  • Principal: The carrier or trucking company

  • Obligee: New Mexico Department of Transportation

  • Surety: The bonding company issuing the bond

If a carrier violates permit conditions or causes damage, NMDOT may file a claim against the bond. The surety may pay the claim, but the carrier must reimburse the surety in full.

Bond Amount and Cost

  • The bond amount is set by NMDOT and may vary based on load size, weight, and route

  • The cost (premium) is usually a small percentage of the bond amount and depends on credit and financial history

Key Takeaway

A New Mexico Overweight or Oversize Permit Bond is a compliance requirement that allows carriers to legally move oversized or overweight loads while protecting state infrastructure. Maintaining the bond helps avoid permit delays, fines, and operational interruptions.
