CA AB1908

Prohibits new high-occupancy vehicle (HOV) lanes on state highways in southern California unless they operate only during hours of heavy commuter traffic, effective July 1, 2017.

Requires existing HOV lanes in southern California to be modified to operate only during peak commuter traffic hours rather than 24 hours.

Requires the Department of Transportation to report to the Legislature by January 1, 2019 on the traffic impact of limiting HOV lane use to commuter traffic hours.

Allows the Department of Transportation to reinstate 24-hour HOV lanes on or after May 1, 2018 if it determines that peak-hour-only operation creates adverse impacts on safety, traffic conditions, or the environment.

The bill becomes inoperative 60 days after the Legislature receives the Department's notice of intent to reinstate 24-hour lanes, and is repealed January 1 of that year.
