Widening spread between $5 diesel and lower gasoline prices baffles truckers

It’s on display at virtually every gasoline station, the price of gasoline in red and the price of diesel in green. It’s as clear as day. But for operators using diesel fuel—including about 3.5 million long-haul truck drivers—it is maddening. There has been an ever-widening gap of as much as $2 or more between the price of gasoline and diesel. While the price of gasoline has plummeted more than 35% from a summer high of just over $5 a gallon nationally to around $3.44 in early December, diesel has remained stubbornly high.
