Are electric vehicles are allowed to use the carpool lane in California with one person?

I thinking about making a piece to replace my Prius has the stickers solo Occupancy. Is it a sheet you can use the carpool lane with just the pilot?

John is right – the stickers are out, from what I heard. My two cars running on natural gas and California to they have the stickers, but I'm in Utah so I do not need them in! They are stuck on the good, and if I can not get to detach. I am sure that all-electric car would be admissible, but if California will not be printed on stickers, I suppose you are "Blocked". Pretty ridiculous, but that seems to be how California is these days …
