Diesel fuel prices have been steadily falling this month, offering relief to truckers and other customers, yet still remain historically high.
Nationally, the average price has fallen 7 cents since last week and 43 cents since Dec. 5 to $4.54, according to the Energy Information Administration.
The average price has remained above $4 a gallon since February for the fuel that's used to transport the bulk of goods purchased by U.S. consumers, and sections of the country including California and New England are still seeing prices above $5.
