I bought my model S back in 2014 and was given white HOV stickers that were good until January 1, 2019. Apparently California is now issuing red stickers that are also good until the same date. But at the end of this year, all stickers will need to be replaced with what I believe will be a yet to be determined color. If you were issued stickers in 2017 and 2018 they will apparently give you the new sticker, but my understanding is my Tesla will no longer be able to be eligible to travel in the HOV lane without multiple people in the car. Am I understanding that correctly? If it is true that is going to be hard to get used to, it was one of my favorite perks about driving this car. I love it otherwise, it's so fun, but this would be a major bummer.
