This guide is the second of two guides available to help your company participate fully in the SmartWay Transport Partnership as a Multi-modal Carrier Partner. The first guide, the Multi-modal Carrier Tool "Quick Start Guide," provides a basic walk-through of the process of identifying, gathering, preparing, and submitting your data using the SmartWay Multi-modal Carrier FLEET Tool. (From this point on, this guide will refer to the SmartWay Multi-modal Carrier FLEET Tool as the "Multi-modal Tool" or simply, the "Tool," for brevity.) The Quick Start Guide may be all you need to successfully complete the Multi-modal Carrier Tool. This guide, the Multi-modal Carrier Tool "Data Entry and Troubleshooting Guide," is intended to supplement the Quick Start Guide and provide more detailed information for completing your tool submission. The Table of Contents for this guide is designed so that you can find the relevant information on specific topics without reading the entire guide.
