A large number of American drivers say that gas prices rising above an average of $4 will force them to make changes to their habits and lifestyles, such as driving less and cutting out entertainment and shopping.

AAA said Thursday that, according to a recent survey, more than half (59%) of U.S. drivers said they would make changes if the average cost of gas rose above $4 per gallon — and about three-quarters said they would do so if it rose to over $5.

AAA said earlier this week that the national average in the United States was $4.17 per gallon — the highest mark on record. On Thursday, AAA put the national average even higher — about $4.32 per gallon.
