HOV lanes are special lanes on highways for carpoolers, transit riders, and motorcyclists. A report from 2000 in the Puget Sound area looked at how well these lanes were working. They found that HOV lanes help people travel faster and more reliably than regular lanes. The report also looked at how many people and vehicles used the lanes, how often rules were broken, and what the public thought. The goal was to help transportation planners make decisions about HOV lanes in the area.
