Transportation: motor carrier fuel tax; certain definitions in the motor carrier fuel tax act; modify. Amends sec. 1 of 1980 PA 119 (MCL 207.211).

This bill updates the definitions within Michigan's Motor Carrier Fuel Tax Act to clarify terms used for calculating and collecting taxes on commercial vehicles. It specifically revises how "motor carrier" and "qualified commercial motor vehicle" are identified, ensuring consistency with related fuel tax laws and including provisions for out-of-state registered farm vehicles. The legislation also standardizes definitions for items like "alternative fuel," "gallon equivalent," and "public roads" to align with existing statutes. While the bill was approved by the Governor, it includes a condition that it will not take effect unless a separate companion bill, House Bill 5379, is also enacted into law.
