Since March ‘21 I have been using the carpool lane solo (5,10,101,405,210, all of them) without a sticker. I have not been pulled over (yet) and refuse to put a sticker on my car. I paid the $22 and have my stickers in my glovebox untouched. I figure that in the event I get an a-hole CHP trying to verify that I’m not “cheating” that he/she would understand that I don’t want to make my beautiful car look like every Prius.
The idea that someone using an EV in a carpool lane illegally is dumb. The purpose of the HOV lane is identical to the concept of EV’s. Any cop who wants to earn his/her $65k/year by giving me a hard time can suck it.
