Fleet Compliance Assistance Tool

This page last reviewed January 28, 2019

Reporting for Larger Fleets:   A compliance assistance tool is available to assist larger fleets with reporting for the 2019 calendar year. It provides the owner the option to download a copy of their fleet information from the Truck Regulation Upload Compliance and Reporting System (TRUCRS). The owner may add vehicle(s) and update existing vehicle(s) information in the spreadsheet. It is designed to be used for fleets that have 20 or more active vehicles to accommodate a large number of vehicles that need to be added or deleted. Once completed, the owner can send the updated information via email to for upload.

Note: Fleets that want to claim a flexibility option must update their option in TRUCRS online, but may submit their vehicle information if they have at least 20 vehicles on the spreadsheet. Submission from fleets with less than 20 vehicles on the spreadsheet will be returned unprocessed.

Fleet Calculator (No Longer Updated):  The Fleet Calculator was an Excel spreadsheet created to assist fleet owners in evaluating various compliance strategies to comply with the Truck and Bus regulation. Since the majority of the flexibility options have expired, the Fleet Calculator tool will no longer be updated for the 2019 compliance year and thereafter. For users who retained a copy of the tool on their computer, be aware that as of December 31, 2018, the results from all versions of the calculator will not accurately reflect the fleet’s compliance status with the Truck and Bus regulation.

If you need further assistance, please email ARB's Diesel Hotline ( or call 866-6DIESEL (866-634-3735).
