What Do Americans Think About Federal Tax Options to Support Transportation? Results from Year Thirteen of a National Survey

This report summarizes the results from the thirteenth year of a national public opinion survey asking U.S. adults questions related to their views on federal transportation taxes. A nationally-representative sample of 2,620 respondents completed the online survey from January 31 to March 10, 2022. The questions test public opinions about raising the federal gas tax rate, replacing the federal gas tax with a new mileage fee, and imposing a mileage fee just on commercial travel. In addition to asking directly about support for these tax options, the survey collected data on respondents’ views on the quality of their local transportation system, their priorities for federal transportation spending, their knowledge about gas taxes, their views on privacy and equity matters related to mileage fees, travel behavior, and standard sociodemographic variables. This large set of variables is used to identify personal characteristics and opinions correlated with support for the tax options. Key findings include that large majorities supported transportation improvements across modes and wanted to see the federal government work towards making the transportation system well maintained, safe, and equitable, as well as to reduce the system’s impact on climate change. Findings related to gas taxes include that only 2% of respondents knew that the federal gas tax rate had not been raised in more than 20 years, and 71% of respondents supported increasing the federal gas tax by 10 cents per gallon if the revenue would be dedicated to maintenance. With respect to mileage fees, just under half of respondents supported some form of mileage fee, whether that was assessed on all travel or just on commercial travel, 58% believe that low-income drivers should pay a reduce mileage fee rate, and 53% thought that electric vehicles should pay a lower rate than gas and diesel vehicles. The analysis of trends across the survey series, which has run from 2010 to 2022, shows that support for both higher gas taxes and a hypothetical new mileage fee has risen slowly but steadily.
