This data can take up to 24 hours on the primary network the unit is issued by (e.g., the New York State Thruway or Illinois Tollway system), but may be delayed by as much as 72 hours on other networks. Tag data is exchanged among the agencies on a nightly basis. This network provides the means to exchange tag data and process toll transactions across the various agencies.
įor purposes of interoperability, all agencies are connected to each other by a secure network (the "reciprocity network"). New York also offers green-colored E-ZPass tags (and a 10% toll discount plan) to qualifying low-emission and zero-emission vehicles. In New York, an orange E-ZPass tag is issued to emergency vehicles as well as to employees of the Metropolitan Transportation Authority, Port Authority of New York and New Jersey, and New York State Thruway Authority. The blue E-ZPass is also used in government employee vehicles. In an attempt to avoid this, E-ZPass tags for commercial vehicles are blue in color, contrasting with the white tags assigned to standard passenger vehicles. This will result in a violation and possible large fine assessed to the tag holder, especially if a lower-class (e.g., passenger car) tag is being used in a higher-class vehicle such as a bus or truck. Examples include:Įach E-ZPass tag is specifically programmed for a particular class of vehicle while any valid working tag will be read and accepted in any E-ZPass toll lane, the wrong toll amount will be charged if the tag's programmed vehicle class does not match the vehicle. In some areas, however (typically recently built or retrofitted facilities), there is no need to slow down, because E-ZPass users can utilize dedicated traffic lanes ("Express E-ZPass" or " open road tolling") that are physically separate from the toll-booth lanes.

Most E-ZPass lanes are converted manual toll lanes and must have fairly low speed limits for safety reasons (between 5 and 15 miles per hour (8 and 24 km/h) is typical), so that E-ZPass vehicles can merge safely with vehicles that stopped to pay a cash toll and, in some cases, to allow toll workers to safely cross the E-ZPass lanes to reach booths accepting cash payments. In April 2013, Kapsch (purchasers of Mark IV Industries) made the protocol available to all interested parties royalty-free in perpetuity and is granting the right to sublicense the protocol. Transponders use active Type II read/write technology. This 915 MHz signal is sent at 500 kbit/s using the TDM (formerly IAG) protocol in 256-bit packets. The E-ZPass transponder works by listening for a signal broadcast by the reader stationed at the toll booth. Transponders may be put in a shirt or jacket pocket, if necessary. Īlthough a tag can be used with a motorcycle, usually no official instructions are given for mounting, due to the numerous variations between bike designs and the small area of a motorcycle windshield which could prove a hindrance if the transponder is attached following automobile instructions.

Some vehicles have windshields that block RF signals for those vehicles, historical vehicles, and customers who have aesthetic concerns, an external tag is offered, typically designed to attach to the vehicle's front license plate mounting points. Though toll agencies advise adherence to the windshield with mounting strips (usually 3M's Scotch brand "Dual Lock" fasteners), third-party options using trays with suction cups to adhere a pass to a windshield temporarily if used in multiple vehicles are available. The most common type of tag is an internal tag that can be mounted on the inside of the vehicle's windshield in proximity to the rear-view mirror. They communicate with reader equipment built into lane-based or open-road toll collection lanes by transmitting a unique radio signature.
