An E-ZPass account holder acknowledges and agrees to comply with the Agreement when opening an E-ZPass account. Discount Toll Programs. The Authority may establish different types of discount toll programs. 2-axle Vehicle Discount Toll Programs. E-ZPass account holders may purchase approved discount toll programs that have a number of trips which are valid for a specified period of time. Trips not used within the period of time specified in the applicable discount toll program are no longer valid. Refunds or credits may not be issued for unused trips. Multi-Axle Vehicle Discount Toll Programs. An E-ZPass account holder may receive a toll discount based on the volume of use by vehicles included on their E-ZPass account. An E-ZPass account holder shall maintain sufficient funds within the E-ZPass account in accordance with the Agreement. If at any time an E-ZPass account balance is insufficient to pay tolls due, an E-ZPass account holder remains liable for the toll and the Authority shall: Send a NOTD in accordance with Regulation .06 of this chapter; Issue a Citation after failure to pay a NOTD in accordance with Regulation .07 of this chapter; and Collect the toll due and any civil penalties that accrue in accordance with Regulation .08 of this chapter. An E-ZPass account holder remains responsible for updating account information with the Authority in accordance with the Agreement. Failure to keep the E-ZPass account information current does not relieve the account holder of liability for tolls due. The use of the transponder is transferable between vehicles listed on an E-ZPass account. Speed Violations — Procedures.
