What is red-dyed diesel and how can it lower fuel costs?

President Donald Trump signed an executive order during a rally in Nebraska to expand the availability of red-dyed diesel. This measure allows individuals to purchase tax-free fuel as Washington seeks to mitigate surging energy prices in the United States before the midterm elections. The order specifically focuses on extending the use of this red-dyed diesel to lower fuel costs for consumers, addressing the economic pressure caused by rising energy expenses across the country.
