WASHINGTON, D.C. --- For the tenth week in a row, average gasoline prices fell in all regions of the country and for the first time since March 7, 2005, the U.S. average price for regular gasoline fell below $2 a gallon.

The national average tumbled 18 cents to hit $1.892 per gallon, settling $2.222 below the all-time high set on July 7 of this year, and $1.205 lower than the price a year ago, the Energy Information Administration (EIA) said in its weekly report issued Nov. 26.
