Massachusetts gas prices rise another 9 cents a gallon, AAA Southern New England says

By Chris Reidy, Globe Staff

The average price for gas in Massachusetts is $3.689 a gallon in the latest weekly AAA survey, up 9 cents from the previous week’s average, AAA Southern New England said Monday.

The previous week’s average was 14 cents higher than that of the week before. The increases are largely driven by a rise in crude oil prices.

The current national average for gas is $3.58 a gallon, AAA Southern New England said. A year ago at this time, the Massachusetts average price was $3.56.

AAA’s weekly surveys look at prices for self-serve, regular unleaded gas.
