Bill Intelligence
The "Cold Weather Diesel Reliability Act of 2025" aims to address issues related to diesel vehicles in cold weather. It acknowledges the vital role of diesel vehicles for transportation and emergency services in such regions, and the challenges faced due to unreliable diesel exhaust fluid systems. The Act directs the Administrator of the Environmental Protection Agency to make regulatory revisions allowing suspension of emissions control functions in extreme cold and granting exemptions for vehicles operating in freezing conditions. It emphasizes that these measures do not waive overall emissions standards. The focus is on ensuring critical mobility and safety in cold weather regions for diesel vehicles and nonroad equipment.
