I received my California license plate and pink slip two months to the day from date of sale. It supposedly took 4 to 6 weeks, but was actually much longer. Then with the license number finally known, I could apply for clean air decals. These allow solo drivers to drive in HOV lanes. I had white ones for my 2011 Leaf, but those expired a few years ago. I don't know how long these new ones will be good for. I've seen purple ones and I think another color, too, but I'm not sure what color I will get, assuming I qualify. Eligibility is income capped and rules seem to change without warning. I'll share details either way. Anyone else with recent experience with these?
