AAA is a federation of motor clubs serving 50 million members in the United States and Canada with automotive, travel, financial and insurance services.

For decades, AAA has published public-service guides on car care, fuel economy and safety. In 1943, AAA published its first guide, Keep 'em Rolling, to assist with gasoline rationing required by World War II.

In the 1970s, when American motorists faced soaring gas prices brought on by the Arab Oil Embargo, AAA published Rolling Along with the Gasoline Shortage and produced its first Gas Watchers Guide.

AAA's companion brochure, Your Driving Costs, has been produced since 1950. That year, driving a car 10,000 miles annually cost 9 cents per mile, and gasoline sold for 27 cents a gallon.
