HOV (High Occupancy Vehicle) lanes decrease driving times, reduce stress and improve the region's air quality. How? The system is designated for carpools, vanpools, and transit buses — all ways of travel that reduce single-occupant vehicles on our busy roads.

Approximately 90 lane-miles of HOV lanes operate on I-75, I-85 and I-20 24 hours a day, seven days a week in the following areas:

  • I-75 inside I-285 (Cobb, Fulton, and Clayton Counties)
  • I-75/I-85 (Downtown Connector)
  • I-85 between Brookwood Interchange and I-285- DeKalb County
  • I-20 east of I-75/I-85 (Downtown Connector) - Fulton, DeKalb Counties

Understanding Lane Striping

  • Solid Double Lines mean traffic cannot change lanes.
  • Broken Lines allows traffic to shift between lanes.
