The move responds to a sharp climb in diesel costs over the past year, according to Federal Reserve Economic Data. A year ago, the national average price for a gallon of diesel sat at $3.754. That number has climbed steadily since, and the state cited the increase as the reason for stepping in.
Dyed diesel gets its red color from an additive that lets tax collectors spot when someone burns tax-exempt fuel in a vehicle meant to run on the taxed kind. Normally, using it on public roads brings steep penalties. The disaster proclamation waives those restrictions for now, letting drivers fill up with the cheaper, dyed fuel instead.
Truckers, farmers, and anyone running diesel vehicles or equipment across Texas could save money at the pump while the order stands. The proclamation doesn't lower the underlying price of diesel itself. It just widens who can legally buy the cheaper, previously restricted fuel, and for an industry running on thin fuel margins, that kind of workaround can add up fast.
