Are any MA residents getting the toll transponder? [View all]

I have visited the Massdot web site to get particulars regarding the new requirement that we must have a transponder to use the Ma Pike, TW tunnel and the Tobin bridge or we are billed and charged more $$ for use. Since I use the toll roads and tunnel less than 6 times a year, I don't feel this is necessary for me. I understand there is a surcharge if you use any toll roads if you don't have this transponder. Nowhere can I find what the surcharge is. Anyone know?

Before signing up for this, I would like to know what I would pay if I don't sign up and install this.

Another intrusion and penalty, in my opinion.
