  • Georgia's Gwinnett County leads as the largest school bus fleet in the United States.
  • The rankings highlight public K-12 school districts by bus fleet size nationwide.
  • Gwinnett County has maintained the top position for five consecutive years.

*Summarized by AI

Looking at the list of the largest school districts this year, based on School Bus Fleet's annual district survey, Georgia’s Gwinnett County remains the leader in fleet size and number of students bussed, overtaken only by Las Vegas’ Clark County in total distance traveled. Georgia’s Cobb County dropped in the rankings this year, nudged out by other East Coast and Southern schools.

This annual ranking highlights the largest public K-12 school district-operated fleets in the U.S. based on the number of buses, students transported, and miles driven. Together, these local operations represent millions of daily student trips and a cross-section of the nation’s most complex pupil transportation networks.
