If you drive a hybrid with a state-issued yellow sticker in the car-pool lanes starting Friday, you better have at least one passenger with you.

The six-year perk that allowed 85,000 hybrid drivers to drive solo in car-pool lanes ends after Thursday evening’s commute.

The Legislature in 2004 created the exemption for hybrids that met the state’s strict partial zero-emissions standards and that got 45 mpg or greater. Drivers of those cars paid an $8 fee and got to slap special yellow stickers on their cars, letting the CHP know they had the right to go solo. The program started in summer 2005.

Drivers of cars with state-issued white stickers can go solo in car-pool lanes until Jan. 1, 2015, and those cars typically are certified pure zero-emission vehicles, such as 100 percent battery electric and hydrogen fuel cell, and compressed natural gas (CNG).

The state plans to launch another car-pool sticker program Jan. 1, offering 40,000 green stickers on a first-come, first-served basis to owners of cars that meet even stricter pollution rules.

The state Air Resources Board’s website — CLICK HERE — says of those vehicles:

“In general, vehicles with the potential of meeting the Enhanced AT PZEV requirement include plug-in hybrid (PHEV) and hydrogen internal combustion engine (hydrogen ICE) vehicles. In order to be certified as an Enhanced AT PZEV, PHEVs and hydrogen ICE vehicles must:
–Meet California’s most stringent tailpipe emission standard
–Have zero evaporative emissions
–Have a 15 yr/150K mile warranty on the emissions system
–Have a 10 yr/150K warranty on the zero emission energy storage system.”

The website notes that not all PHEV and hydrogen ICE vehicles will meet the requirements.

The website at this point lists only one car that meets the green-sticker requirement: The 2010 Toyota Prius plug-in hybrid. Check the website for specifics for green and white stickers.
