1. Interstate Authority
If you carry freight across state lines (including Oregon → New Mexico), you must have valid interstate operating authority from the Federal Motor Carrier Safety Administration (FMCSA). This includes:
-
MC Number
-
USDOT Number
-
Proper liability insurance on file with FMCSA
Operating without this authority can lead to fines or out-of-service orders.
2. IFTA (International Fuel Tax Agreement)
Oregon and New Mexico are both IFTA member jurisdictions.
-
If your Oregon-based carrier travels through New Mexico and uses highway fuel, you must be registered under IFTA.
-
IFTA allows you to file one fuel tax return covering all member states.
IFTA decals must be displayed on qualified vehicles.
3. IRP (International Registration Plan)
Oregon carriers with vehicles traveling into New Mexico will typically need IRP registration if:
-
The vehicle operates across state lines, and
-
The combined weight exceeds 26,000 lbs.
IRP apportions registration fees to all states traveled based on miles driven.
4. New Mexico Weight Distance Tax, register at https://www.newmexicotruckingonline.com/
New Mexico imposes a weight-distance tax on certain carriers operating on New Mexico highways. Oregon carriers traveling through the state may need to register and pay this tax depending on:
-
Vehicle weight
-
Miles traveled in New Mexico
This is separate from standard fuel tax.
5. New Mexico Oversize/Overweight Permits at https://www.newmexicotruckingonline.com/
If a vehicle or load exceeds size or weight limits, a special oversize/overweight permit is required before travel.
Examples include:
-
Wide loads
-
Heavy machinery
-
Long trailers
Permits are issued by New Mexico’s Motor Transportation Division.
6. Trip and Fuel Permits at https://www.newmexicotruckingonline.com/
For carriers not registered under IFTA or IRP—such as short-term or one-time trips—Oregon carriers may need:
-
Trip Permits
For single or short operations across New Mexico without long-term registration. -
Fuel Permits
If you are not IFTA-registered but operate temporarily in the state.
7. Unified Carrier Registration (UCR) , register at https://www.fmcsa.me/
Oregon carriers must maintain a current UCR registration based on fleet size if operating interstate, including in New Mexico.
UCR fees are paid annually to a base state but cover operations in all states.
