I would check with the DMV, the Ca DMV is getting pretty crazy. They (CHP) ticketed my truck with expired tags while it was parked at my house. Twice. They had to walk past 3 unregistered racecars to get to it.
Boats are a little different but we're dealing with crazy people here.
When I registered my dinghy
in SF they told me that I had to bring the smog tag from the outboard
in to register the boat. I told them that I didn't have a motor
yet. They said that I didn't need to reg. the boat then. I said I wanted to anyway because I was planning to buy a used outboard
that week. They said to bring the smog tag in after I bought the outboard. I explained that there were no smog tags on old outboards. They said that I couldn't get an old outboard for my new dinghy
, that I had to buy a new outboard because there was no box to check on the form for a used outboard on a new dinghy. Crazy people.
