Gas prices in California have dropped for the twelfth consecutive week, according to AAA.
The average price in the state for a gallon of regular unleaded gas is $3.46, a decrease of 39 cents from Sept. 9.
The association reports the average price of unleaded gas in the Bay Area is $3.63 per gallon, and the national average is $3.16, down about 50 cents from last month.
"It's reasonable to expect the average retail gasoline price will keep dropping," AAA Northern California spokesman Matt Skryja said in a prepared statement. "Consumers continue to cut back on using gas, as the economic crunch is helping to dictate how much they drive."
The average price of gas in San Francisco is $3.62 per gallon; $3.64 in Oakland; $3.48 in Santa Rosa; and $3.57 in San Jose.
Alaska has the country's highest average gas price, at $4.07 per gallon.
Among the lower 48 states, the most expensive gas is in Tahoe City, Calif., where a gallon of unleaded costs $3.89.
