No, they are not the same, but they are often mentioned together for a few reasons. Both are base state registration agreements with the same parameters for qualification, and the distance records a motor carrier keeps are often shared between the two programs. And, both apply to interstate vehicles that:
- Have a gross weight or registered gross weight that exceeds 26,000 pounds; or
- Have three or more axles regardless of weight (count axles on the truck/power unit only, do not count trailer axles); or
- Are operated in combination and the combination exceeds 26,000 pounds gross weight or registered weight.
But, it is important to understand that they are two very different, and separate, programs. IFTA covers the carrier for fuel taxes, while IRP covers the registration (plates) of the vehicle.
