This is a follow up of my post the other day on trailer plates. I went to the DMV today to get a new plate and sticker for my trailer, old plate was beat up and ready to fall off. Anyway I asked about the ST (semi-trailer) plates which is only $18 and it's a forever plate no sticker renewal etc. The catch to the ST plate is no matter what size trailer you register it to that trailer has to be state inspected annually and every weigh station you run up on you have to go in and weigh. YOu'll be subject to all the laws pertaining to big trailers for which you may have only a 5x10 trailer. They said this is a loop hole for being a For-ever Plate but the lady behind the counter said all those purchasing the ST plates for their little trailer will soon be going back to the TA plates. So I just bought the TA plate and sticker.
