, according to the Department of Energy.

Trucking's main fuel landed at a national average of $2.946 a gallon this week, the fourth straight weekly drop, according to the DOE's Energy Information Administration. Over the last four weeks, diesel has slipped 18.1 cents.

The Gulf Coast and Midwest regions saw the lowest averages this week, at $2.899 a gallon and $2.904, respectively. Meanwhile, diesel remained above $3 in many regions, including the Central Atlantic and West Coast regions, where prices hit $3.09 and $3.058 a gallon, respectively, the highest in the nation.

Crude oil prices were down Monday, as uncertainty over the economic recovery continued to dominate market sentiment, according to reports by Dow Jones.

Crude oil fell 0.1 percent, or 7 cents, Monday to end trading at $71.44 a barrel on the New York Mercantile Exchange, Dow Jones said. The publication attributed the decline to investor concerns that oil supplies still outweigh demand. The commodity also moved alongside equities, which saw a rough trading day as well, MarketWatch reported.
