cgsincc,
You should be able to go through as long as you have already bought the toll tag and have it registered to the Cobra. When it errors their system will look up the license plate and see if there is a toll tag registered to it. If you do get a ticket in the mail, just call them and say you have a toll tag and don't understand why you got the ticket. The will look up the toll tag, charge the amount for the tolls only, and waive all fees from the ticket.
