LOS ANGELES, CA - FEBRUARY 03: Drivers use the High Occupancy Vehicle (HOV) lane (C), also called the diamond or commuter lane, at sunset on the 118 or Ronald Reagan Freeway on February 3, 2005 near Simi Valley, California. To encourage sales of environmentally-friendly hybrid cars, lawmakers are contemplating legislation that would allow states to determine whether to allow hybrid vehicles with no additional passengers to be driven in highway HOV lanes, currently reserved only for motorcycles and vehicles carrying multiple passengers.

Carpool lanes in San Diego and other parts of California will soon be off limits to solo drivers of hybrid vehicles.
Even those with the yellow clean air stickers will not enjoy the advantage starting June 1.
To notify car owners with these stickers, the DMV will mail out over 85,000 letters in May.
The next set of clean air stickers is anticipated to be released 2012.
The change will help solo drivers in as many as 40,000 advanced technology vehicles to use carpool lanes.
