Good news for the millions of drivers on American roads: Gas prices are falling. The national average for a gallon of gas has hit a three-year low, the American Automobile Association (AAA) recently announced. As of Sunday, the national average cost for one gallon of regular gasoline sat at $3.01, according to AAA. That’s the lowest in more than three years, the automotive agency reports. AAA made the announcement on Thursday when gas prices plunged to an average of $3.03 per gallon. However, a few days later, the prices went even lower — nearing below the $3 mark that was last recorded on May 11, 2021, according to AAA. “The national average is tantalizingly close to falling below $3 a gallon, and it could happen in a few days,” Andrew Gross, AAA spokesperson, said in a news release. “But 32 states already have an average below or well below $3. Hockley County, Texas, appears to have the lowest county average, at $2.30.” As of Sunday, AAA says the states with the most expensive average prices for gasoline are: Hawaii ($4.56 per gallon) California ($4.39) Washington
