19 / IRP REGISTRATION AND DISTANCE RECORDS
IRP registration and distance records
IRP distance reporting must trace back to each vehicle’s actual trips, including empty, intrastate and repositioning movements. A California-to-neighboring-state trip illustrates what the driver keeps and how the office summarizes it.

California-based IRP registrants; this topic covers eligibility considerations and records, not a complete plate application, weight authorization or operating-permit determination.
Start with these requirements
IRP registration requires actual interstate use or a verifiable plan for interstate operation
- What the rule requires
- The DMV handbook limits apportioned registration to commercial vehicles traveling interstate or with verifiable interstate intent, supported by travel records or contracts. Vehicles operating solely within California or another single jurisdiction are not eligible for apportioned registration. Lower registration cost alone is not an eligibility basis.
Only commercial vehicles that travel interstate or “intended” to travel interstate are eligible for apportioned registration. “Intent” will be established by records of travel and verifiable contracts.
Vehicles traveling solely in California or in another jurisdiction are not eligible for apportioned registration and are subject to 100 percent regular registration fees.
The fact that a vehicle is not used in more than one jurisdiction for the entirety of a registration year and for six additional months gives rise to a presumption that the registrant did not intend to use the vehicle in more than one member jurisdiction.
Uses a fixed source edition; check the original and statutory history for operative dates and exceptions.
Keep evidence for every movement
- What the rule requires
- Non-vehicle-tracking trip records should show dates, origin and destination, actual route, beginning and ending meter readings, total and jurisdiction distance, and vehicle identification. Accountable distance includes intrastate, empty, deadhead, bobtail, toll and non-toll, off-highway movements and relevant distance while trip-leased to others.
Source records are the documents completed by the driver for each trip made by an apportioned vehicle. The common source records are the driver’s trip sheets, trip reports, trip envelopes, etc. These documents are for recording trip and distance information of individual apportioned vehicles, and help the auditor determine the accuracy and validity of total distance and allocation of in-jurisdiction distance.
The Plan Section 1010 “Contents of Records” in part state “Records containing the following elements shall be accepted by the base jurisdiction as adequate under the Plan Section 1005(a)”:
For records produced by a means other than a vehicle-tracking system:
the beginning and ending dates of the trip to which the records pertain the origin and destination of the trip the route of travel the beginning and ending reading from the odometer, hubodometer, Engine Control Module (ECM), or any similar device for the trip the total distance of the trip the distance traveled in each jurisdiction the vehicle identification number or vehicle unit number
10.030 – ACCOUNTABLE VEHICLE DISTANCE
All movements generated by the power units apportioned in the fleet are accountable distance and must be recorded and reported including:
Interjurisdictional and intrajurisdictional distance Loaded and empty distance Deadhead and/or bobtail distance Toll and non-toll distance Off-highway distance
It also includes distance accrued by apportioned vehicles trip leased to other carriers or individuals.
Uses a fixed source edition; check the original and statutory history for operative dates and exceptions.
Retain source records with summaries
- What the rule requires
- Prepare vehicle/jurisdiction/month summaries and quarterly and annual totals supported by trip records. IFTA quarterly fuel-tax schedules alone are not acceptable IRP audit summaries. Keep application-supporting records for three years after the registration year closes; vehicle cost and declared or combined gross-weight records for four years after the close of the registration year in which the vehicle was deleted.
Distance RecordsIn accordance with CVC Section 8057(a), any registrant whose application for apportioned registration has been accepted shall preserve all the records on which the application is based for a period of three years after the close of the registration year. Vehicle cost and declared or combined gross weight records shall be retained for four years after the close of the registration year in which the vehicle was deleted.
Cost RecordsIn accordance with CVC Section 8057(a), vehicle cost records must be preserved for four years after the close of the registration year in which the vehicle was deleted.
From the information recorded on the source records, the registrant must prepare and maintain a monthly summary to recap the total distance traveled by each apportioned vehicle in each jurisdiction during the calendar month by fleet, jurisdiction, and equipment number.
To be acceptable for audit, monthly summaries must be fully supported by the source records and reasonably reflect the months in which the trips were made. Monthly summaries must agree with and provide ready support for the quarterly and yearly summaries.
From the monthly summaries, the registrant must prepare and maintain a quarterly summary that recaps, by equipment number, by jurisdiction and by fleet, the total distance traveled in each jurisdiction during each quarter of the registered year.
Preparing quarterly summaries does not relieve the registrant of the responsibility to prepare and maintain monthly summaries in the manner as described in Section 10.045 of the IRP Handbook.
Note that the International Fuel Tax Agreement (IFTA) Quarterly Fuel Use Tax Schedules are not acceptable summaries for IRP audit purposes.
From the monthly or quarterly summaries, the registrant must prepare a yearly summary that recaps the total distance traveled in each member jurisdiction during the reporting period by fleet, month/quarter, and jurisdiction.
Uses a fixed source edition; check the original and statutory history for operative dates and exceptions.
WORKED EXAMPLE
Loaded miles recorded, empty return omitted
Illustrative example: an IRP vehicle delivers across state lines, but the office has only delivery-ticket mileage, not empty-return distance or jurisdiction records.
Reconstruct the actual trip
Supply dates, route, meter readings and jurisdiction-distance support, including the empty return. Mark missing evidence honestly rather than presenting estimates as original records.
Reconcile summaries
Reconcile continuity by vehicle and month, then update quarterly and annual summaries with supporting records.
A tax form is not a complete mileage trail; registration reporting must trace to the vehicle and trip.
Common mistakes in day-to-day work
Misconception: any ELD mileage is enough
Confirm the export meets IRP record requirements and can be reconciled by vehicle and jurisdiction; one total-mileage figure is insufficient. Check the applicable IRP rules for the specific electronic-tracking fields.
