Record diesel prices are crushing California's truckers, forcing them to adjust to avoid losses as they grapple with the most expensive pump prices in the country. Greg Dubuque's 40 drivers are in a constant diesel-devouring loop. Their big rigs pick up loads of electronics, office furniture and other goods around Los Angeles.

One tank of gas for his vehicles cost $600 a couple of months ago. Today it costs $1,000.

"Now it’s really out of control.” The average price of a gallon of diesel in California got close to $7.75 this week, up 50% from a month ago, according to the American Automobile Assn. The national average of diesel is closer to $5.65 at recent peaks.
