We recently moved to Florida from the midwest and brought our 2013 S85 with us. First, I called SunPass and got the external transponder since my Tesla is one of the older ones. Was able to install it myself after watching a couple of youtube videos, no problem. Then I wanted to have free access to the I95 and hopefully soon I75 express lanes. Following the instructions on the I95 express web site, I went to the DMV office to fill out the form and get an HOV sticker, which is green. Put the green sticker on my car window as directed. Then I got a warning letter from the I95 express lane people and realized that there is another step to register as an electric vehicle once you get an HOV sticker, so I went to the I95 express web site, registered again as a hybrid/electric vehicle, and got a different orange sticker in the mail a few days later. It also came with a shield bag for my transponder and some wording saying if I forget to shield the transponder I am liable for any tolls. Not sure how one goes about shielding the externally mounted transponder... I guess my questions are: - Should I display the green sticker, the orange sticker, or both? Seems like sticker overkill. - Has anybody had problems being assessed tolls for not shielding the transponder? Thanks in advance for any help.
