High Occupancy Vehicle (HOV) lanes, also known as carpool lanes, have been in operation in Los Angeles County since 1973. The first HOV lane, known as the El Monte Busway on Interstate 10, began as an exclusive lane designed to carry buses. Today, after almost 30 years of operation, this HOV lane carries almost half of the people on the freeway during the peak hours.

By the end of 2000, HOV lanes made up a total of 35 percent of the 527 miles of freeway in Los Angeles County. Approximately 700,000 people use HOV lanes every day in Los Angeles County. The benefits of adding HOV lanes include.

  • moving twice as many people as a regular traffic lane (during peak hours)
  • decreasing commute times for all drivers
  • promoting ridesharing
  • reducing traffic congestion
  • lessening the hours of congestion
