BOISE, Idaho (KTVB) -- Idaho drivers are cheering as prices at the gas pump continue their free-fall. After months of having some of the highest prices in the country, gas prices in Idaho are now nine cents below than the national average.

Currently, the average price in Idaho for a gallon of regular unleaded is $2.12, according to AAA. That's just over a dollar less than this time a year ago. Prices have plummeted 82 cents per gallon over the last month. Many local stations are now boasting fuel for under two dollars a gallon.

Nationally, motorists in 38 states can find stations selling gas under the two dollar mark. It's the Oil and gas analysts say it's uncharted territory. The unprecedented drop in prices is due, in part, to Saudi Arabia's decision to keep pumping oil to drive down prices and drive out competitors like Iran, Russia, and even the U.S. Economists say the big drop in pump prices should mean big savings - $500 to $700 per vehicle - for families in 2015.
