Understanding the Basics of Weight Distance Tax

New Mexico’s Weight Distance Tax is for commercial vehicles over 26,000 pounds, based on miles traveled and vehicle weight.

This approach means heavier vehicles, which cause more road wear, contribute more to infrastructure upkeep.


Why Not a Traditional Fuel Tax?

Most states use fuel taxes to collect revenue from trucking. Fuel taxes work less well in some cases.

1. Fuel Purchases Don’t Always Reflect Road Usage

Truckers may fuel up in one state but drive mainly in another, causing a tax mismatch.

2. Heavier Trucks Cause More Damage

Heavier trucks cause more wear than lighter ones, regardless of fuel use.

3. Improved Fuel Efficiency Changes Revenue

Modern trucks use less fuel, reducing tax revenue even as road use continues.


Why New Mexico Chooses Weight Distance Tax

New Mexico links the tax directly to road use.
