Must-know rules

New Mexico stops all qualifying commercial vehicles at its ports of entry, and it charges a separate weight-distance tax (WDT) on trucks over 26,000 lb, on top of IFTA and IRP. I could not confirm anything on chain/traction rules, idling limits, or hazmat routing/tunnels, so those are left out. Several items below rest on non-government sources, so check them with MVD or the Taxation and Revenue Department (TRD) before you roll.

• Must knowPort of entry stops

  Commercial motor carrier vehicles must use designated highways and stop at every operating port of entry for manifesting and clearance stickers. Interstate vehicles of 10,001 lb or more (GVWR/GCWR or actual) are covered, and intrastate-only vehicles of 26,001 lb or more.

• Must knowWhat happens at the port of entry

  Motor Transportation Police check height and weight (gross and axle), issue state oversize permits, IFTA permits and trip permits. They also verify credentials, collect taxes and fees, and do driver and mechanical inspections.

Fees and DOT requirements

New Mexico's CDL fee is low: $18 for a four-year license or $34 for an eight-year license. Registration for trucks over 26,000 lb is a flat fee by declared gross weight. For example, 26,001 to 48,000 lb costs $118 and 48,001 lb and over costs $172. The bigger recurring cost is the weight-distance tax, which was raised 35% on July 1, 2026.

Class B CDL

$18 for 4 years (about $4.50 a year)
MVD's CDL fee page gives one fee for all CDL classes: $18 for four years or $34 for eight years. I did not find a separate Class B fee. The 8-year fee for Class B would be $34. Moving from out of state adds $15. A commercial permit costs $10. Class B knowledge tests are general knowledge and air bra Source

Class A CDL

The fee is the same as Class B: $18 for four years or $34 for eight years. The 8-year fee for Class A would be $34. Class A knowledge tests are general knowledge, air brakes and combination. No official MVD fee for the knowledge tests was found. The commercial permit is $10. Skills-test fees are cha Source

How registration is figured

Flat annual fee by declared gross weight (not by value). A New Mexico-titled vehicle with a declared gross vehicle weight over 26,000 lb is issued a WD plate. The statute schedule is $118 for 26,001 to 48,000 lb and $172 for 48,001 lb and over.
Both amounts come from the Section 66-6-4 schedule as reproduced on Justia, an unofficial copy of the statute. The 2026 increase does not appear to touch trucks. The state says the 25% registration increase does not affect trucks, RVs, motorcycles or buses. A 2023 bill proposed higher truck fees, but the 2024 statute text still shows $118 and $172, so it does not appear to have been enacted. I did Source Non-government source

Carriers hauling persons or property for hire point to point inside New Mexico must obtain authority from the PRC.

State DOT requirements

• Must knowWeight-distance tax (WDT) and permit

  The Weight Distance program, IRP, IFTA and Tax ID cards are all handled through MVD's commercial program. The tax applies to intrastate and interstate commercial vehicles over 26,000 lb declared gross weight. It is based on weight and New Mexico miles. Rates rose 35% effective July 1, 2026. Per-vehicle permit fees and per-mile rates were not verified from an official current rate sheet. Use the Taxation and Revenue Department's current rate sheet.
