US President Donald Trump signed an executive order this month to expand access to tax-exempt diesel as soaring prices frustrate voters ahead of midterm elections. But farmers say it is too risky to use the fuel on public roads, while some other drivers do not have access to it.
Trump has sought to lower prices and boost his sagging approval ratings through a series of actions focused on fuel, including an $8 billion financial support program he announced on Monday to offset diesel costs for farmers during the autumn harvest.
