A key topic raised during our 2020-2021 National Truck Pilot was the need for policymakers to understand and leverage existing regulatory frameworks like the International Fuel Tax Agreement (IFTA) and the International Registration Plan (IRP). Prior Coalition work conducted during our 2018-2019 Multi-State Truck Pilot showed that for commercial vehicles, IFTA and IRP may offer foundational frameworks upon which payment, compliance, and enforcement efforts can build. However, there are knowledge gaps that exist with regards to how IFTA and IRP work, what data is collected, and which vehicles fall under each system.
To address the gap in knowledge, our 2020-2021 Mileage-Based User Fee (MBUF) Work included development of a technical memorandum outlining the history of both IFTA and IRP, how states came together to form uniform agreements, and how the IFTA and IRP frameworks could advance the implementation of mileage-based user fees. See the technical memorandum here.
The Coalition’s next phase of MBUF work, commencing in late spring 2022, will include an International Truck Pilot. This pilot will further explore these models and include an IFTA proof of concept.
