AAA Carolinas says South Carolina drivers have paid the least for gas in the nation in 2013 -- for the second year in a row.
The travel organization said the average price for a gallon of gasoline in the state was $3.24 in 2013, 25 cents below the national average of $3.49 a gallon. California had the highest gas prices in the continental U.S. at $3.89 a gallon.
AAA Carolinas says South Carolina also had the lowest gas prices in the nation in 2012 at $3.35.
The state has the lowest prices in the nation in large part because South Carolina also has one of the lowest gas taxes in the country. The state's gas tax is just under 17 cents a gallon, unchanged since 1987.
Never miss a local story.
Palmetto State drivers, however, paid 64 cents more a gallon last year than in 2010.
Lowcountry motorists shelled out the most at the pump in 2013, while Upstate commuters paid the least for fill-ups, AAA found.
