A step-by-step guide for trucking companies to legally use dyed fuel on highways while the exemption is active

The Biden administration’s temporary lift on the dyed‑diesel ban has opened a new avenue for trucking fleets to reduce fuel costs and comply with federal regulations. With the 30‑day window still open, companies can take advantage before the ban re‑imposes. This guide walks you through securing the dyed fuel, updating your fleet, and staying compliant.
Start by searching the EPA’s Red Diesel Supplier Directory or the Department of Transportation’s Fuel Dispenser Registry to locate a certified supplier in your region. Verify that the supplier is authorized to distribute red-dyed diesel for on‑road use and request a certificate of compliance. This ensures your fuel meets federal standards and protects you from potential penalties.
Check your vehicle’s manufacturer manual or use the Tire & Fuel Check app to confirm that your engine can handle dyed fuel without affecting performance. Ensure the fuel system’s seals and filters are rated for red-dyed diesel, which contains additives that may differ from standard fuel. This step prevents costly engine damage and keeps your fleet running smoothly.
Log into the FMCSA portal and submit the required exemption form, providing details about the fleet and the dyed diesel supplier. Attach the supplier’s certification and your fleet’s fuel usage records to expedite approval. Once registered, your vehicles can legally use red-dyed diesel on highways for the next 30 days.
Use a fuel tracking app like Fuelio or TruckLog to record each dyed fuel purchase and consumption. Mark the entries with the keyword fuel logs so that audits can quickly verify compliance. Accurate logs also help you track cost savings and fuel efficiency gains during the exemption period.
Send a brief safety briefing via your fleet management platform, emphasizing that dyed diesel is safe for on‑road use under the current exemption. Highlight the drivers role in monitoring fuel levels and reporting any anomalies. Training videos and quick-reference cards can reinforce the message and reduce confusion on the road.
Set a reminder in your fleet calendar to start exploring alternative fuel options or negotiating a permanent exemption by the 30‑day deadline. Use the exemption expiration date to schedule maintenance, fuel procurement, and compliance checks. This proactive approach ensures you’re not caught off‑guard when the ban returns.
Compile all exemption paperwork, supplier certificates, fuel logs, and driver confirmations into a single audit file. Use the EPA’s online compliance reporting tool to submit a final report before the exemption ends. Maintaining a thorough compliance record protects your company from fines and demonstrates responsible fuel management.
The exemption only applies to fuel used for off‑road equipment; ensure your truck’s mileage is correctly logged to avoid penalties.
By following these seven steps, your fleet can legally use red-dyed diesel on highways, reduce costs, and stay compliant during the temporary exemption. You’ll have a clear process for procurement, logging, and audit readiness. Next, keep an eye on federal updates to secure a longer‑term solution for dyed fuel use.
