I-pass / EZ-Pass / I-Zoom transponder question

ipass isnt going anywhere. IDOT offers 2 options, the normal white transponder or the blue one(for fleet use)-both work for a CMV and on all ezpass,izoom lanes (with an additional charge of a few cents). The only units ive seen (and been told by IDOT) is the windsheild unit(that may not be correct as the ipass people get moody and try to hurry you of the phone). As far as theft-let them try it. The plate # is videod with the transaction-so ANY toll that isnt registered with the matching plate(s) is a ticket to that vehical (with intrest).
