A group of Arkansas trucking companies is asking Congress to look into record high diesel fuel prices.

According to KATV.com, the Arkansas Trucking Association says the high prices are threatening the general economy and the flow of goods throughout the country.

The trade group, based in Little Rock, wants Congress to hold hearings on the problem. Association President Lane Kidd says Congress should examine why diesel supplies are plentiful but prices keep rising and consumption is flat.

The group includes representatives from ABF Freight Systems at Fort Smith, FedEX Freight at Harrison, P.A.M. Transportation Services in Tontitown, and USA Truck Inc. at Van Buren.
