San Joaquin Valley Has 1,300+ Drive-Throughs; 197 in San Joaquin County Impact Air Quality
A Central Valley Journalism Collaborative investigation found roughly 1,300 fast-food and coffee drive-through lanes across the San Joaquin Valley, where idling vehicles emit hydrocarbons, nitrogen oxides, carbon monoxide, and other pollutants. In San Joaquin County, 197 drive-throughs operate, with 96 in Stockton; Stanislaus County has 188, including 102 in Modesto. The Valley remains a federal nonattainment region for ozone and PM 2.5, yet no regional or state air quality regulator has specifically studied the contribution of drive-through idling to that pollution. Researchers note that while individual emissions are small, concentrated exposure at restaurant sites affects drivers, employees at pickup windows, diners inside, and nearby pedestrians.
