The document discusses record keeping requirements for commercial vehicles that operate in multiple jurisdictions under the International Fuel Tax Agreement (IFTA) and International Registration Plan (IRP). It states that vehicle operators must complete an Individual Vehicle Distance Record (IVDR) for each trip, recording dates, routes, odometer readings, fuel purchases, distance traveled, and in-jurisdiction distance. Operators must retain IVDRs and fuel receipts for 4 years to comply with IFTA and IRP regulations and be subject to audit. Failure to maintain proper records can result in fines and loss of IFTA and IRP credentials.
