Indiana Code Title 9. Motor Vehicles § 9-21-3.5-13

Sec. 13. (a) For purposes of this section, “transponder” means a device, placed on or within a motor vehicle, that is capable of transmitting information used to assess or collect tolls.  A transponder is “insufficiently funded” when there are no remaining funds in the account in connection with which the transponder was issued.

(b) Any police officer of Indiana may seize a stolen or insufficiently funded transponder and return it to the department, the authority, or an operator, except that an insufficiently funded transponder may not be seized from the holder of an account sooner than the thirtieth day after the date the department, the authority, or an operator has sent a notice of delinquency to the holder of the account.

(c) The department or the authority may enter into an agreement with one (1) or more persons to market and sell transponders for use on tollways, toll roads, or qualifying projects.

(d) The department, the authority, or an operator may charge reasonable fees for initiating, administering, and maintaining electronic toll collection customer accounts.

(e) Electronic toll collection customer account information, including contact and payment information and trip data, is confidential and not subject to disclosure under IC 5-14-3.  A contract for the acquisition, construction, maintenance, or operation of a tollway, toll road, or qualifying project must ensure the confidentiality of all electronic toll collection customer account information.
