MC 2118I Form – The MC 2118I Form, officially titled California IRP Vehicle Data – Schedule C, is a critical document issued by the California Department of Motor Vehicles (DMV) for commercial vehicle operators participating in the International Registration Plan (IRP). This form is used to report detailed vehicle data as part of apportioned registration applications, renewals, additions, deletions, weight changes, or replacements under the IRP program.
IRP allows interstate and international commercial fleets to register vehicles in a single base jurisdiction (like California) while paying registration fees proportionally based on miles traveled in each participating jurisdiction. The MC-2118I serves as Schedule C in this process, focusing specifically on vehicle identification, weights, and fee calculations.
The current official version is the MC 2118I (R1-2015 revision), uploaded to the DMV website in November 2024 and remains the standard form in 2026.
Why the MC 2118I Form is Required for California IRP Registration?
California requires the MC 2118I for all IRP-related actions involving commercial vehicles operating across state lines or internationally. It works in tandem with the companion California IRP Carrier Data Schedule A/B (MC 2117I) form to provide the DMV with complete carrier and vehicle information.
Key uses include:
- New IRP carrier or fleet account applications
- Annual renewals
- Adding or deleting vehicles from a fleet
- Increasing or decreasing declared weights
- Replacing credentials or equipment
Without a properly completed Schedule C (MC 2118I), your IRP application will be rejected. The form ensures compliance with federal IRP standards and California Vehicle Code requirements, including accurate reporting of USDOT numbers, TIN/FEIN, and safety responsibility data.
Who Must Complete the California IRP Vehicle Data Schedule C (MC 2118I)?
Any California-based or California-registered commercial carrier operating vehicles in two or more IRP jurisdictions (48 U.S. states, 10 Canadian provinces, plus others) must file this form. This includes:
- Trucking companies and fleet operators
- Mexico-based carriers authorized for U.S. operations
- Owners of apportioned vehicles such as trucks, tractors, buses, and certain trailers
First-time applicants, existing fleets making changes, and renewing carriers all rely on the MC 2118I to list every vehicle in the fleet with precise specifications.
