The is my opinion only but personally, I don't think Hybrid vehicles should be allowed in the HOV lanes , green plates or not. At highway speeds, Hybrids would be using their gas guzzling engines would they not? So much for green energy in this case. I think Green plates should only be given to all electric cars such as the Tesla Model S, the Tesla Model S and the Tesla Model S. Also the Roadster and a few other all electric vehicles and that's it. Green plates are issued because the vehicles they are attached to are supposed to be fully sustainable energy cars. Hybrids don't fit into that category. They are simply a gas car with a little bit of battery power. It still goes through a lot of gas. Again, my opinion on this and perhaps any of us with a hybrid might only use the battery power for the most part in town anyway and only use the gas part on long trips. So who am I to speak? LOL!
