Idaho's average gas price has inched ahead of the national average, following a nearly six-cent increase last week.
The average price in Idaho is $3.85, AAA Idaho reports. Nationally it is $3.84. Idaho had been below the national average since Aug. 1
Idaho's average prices have risen 28 cents a gallon in the past month. Idaho's average is still lower than the $4.04 and $4.06 averages in Oregon and Washington.
Prices may stabilize, said Dave Carlson, AAA Idaho spokesman. Its reasonable to assume that the national average price will decline as demand drops off following the busy summer driving period, Carlson said.
