On March 7, 2025, the Illinois House of Representatives introduced House Bill 1390, a legislative measure aimed at tightening regulations surrounding the use of dyed diesel fuel. This bill seeks to address concerns about the illegal use of dyed diesel, which is typically taxed at a lower rate and is intended for off-road vehicles and equipment, not for highway use or recreational watercraft.

The key provisions of House Bill 1390 include significant penalties for individuals and businesses that possess, sell, or distribute dyed diesel fuel for unauthorized purposes. Under the proposed legislation, individuals caught knowingly using dyed diesel fuel in highway vehicles or recreational watercraft could face a Class A misdemeanor for the first offense and escalate to a Class 4 felony for subsequent violations. Additionally, penalties for selling or transporting dyed diesel without proper notice could reach up to $5,000 for repeat offenders.

The bill has sparked notable debate among lawmakers and industry stakeholders. Proponents argue that the legislation is essential for ensuring fair tax compliance and protecting the integrity of fuel regulations. They emphasize that the misuse of dyed diesel fuel undermines state revenue and creates an uneven playing field for businesses that adhere to the law. Conversely, opponents express concerns about the potential burden on small businesses and the feasibility of enforcing such stringent penalties.

The implications of House Bill 1390 extend beyond regulatory compliance. Economically, the bill could impact fuel distributors and consumers, potentially leading to increased fuel costs if compliance measures are passed down. Socially, it raises questions about the balance between enforcement and support for local businesses, particularly in rural areas where dyed diesel is commonly used for farming and other legitimate purposes.

As the bill progresses through the legislative process, experts suggest that its passage could lead to a more robust framework for fuel regulation in Illinois, but it may also necessitate additional resources for enforcement and education to ensure that all stakeholders understand the new requirements. The outcome of this bill could set a precedent for how fuel regulations are managed in the state, influencing both economic and environmental policies moving forward.
