American drivers, start your engines.
With crude oil prices falling and supplies continuing to rise, U.S. motorists are paying on average some of the lowest prices to fill up that they have in years.
The average price for a gallon of regular gasoline this year was the second-lowest of the last 10 years, according to AAA, which tracks national and local pump prices. Gas is cheaper than it's been since 2009, when the Great Recession sidelined millions of workers and prompted many car owners to cut back on driving.
The annual average price was $2.40 per gallon — or about 94 cents less than 2014. That saved Americans more than $115 billion this year, AAA estimates, or an average of more than $550 per licensed driver.
