What is All Electronic Tolling (AET)?

All Electronic Tolling (AET) is a form of toll collection that allows drivers to pay their toll without stopping or slowing down. AET is safer, quicker, and more convenient for our customers.

Effective Monday July 21, 2014 at the Tobin Memorial Bridge, motorists will no longer need to stop at a toll booth to pay cash for their toll or slow down to pass through an E-ZPass lane. Tolls will be collected electronically; either through the motorist's E-ZPass transponder or via the PAY BY PLATE MA program.

E-ZPass customers will notice that travel through an AET toll zone will not provide the traffic light that indicates; "Thank You", "Call E-ZPass" or "Low Bal". Please ensure your E-ZPass account is always current.

Customers without an E-ZPass transponder will receive a PAY BY PLATE invoice in the mail. The registered owner of the vehicle will receive the invoice. Commercial customers will also see a 50 cent surcharge per toll.


As you travel on the Tobin Memorial Bridge without an E-ZPass transponder, a camera captures an image of your vehicle's license plate. A PAY BY PLATE invoice for the toll is mailed to the vehicle's registered owner. Several convenient payment options are provided, including paying on-line and cash payments using self-service kiosks with cashier assistance at retail cash payment locations. (A convenience fee of $2.95 per PAY BY PLATE MA invoice payment will be charged for cash payments.)

To pay online, you will need your Invoice and License Plate numbers. If you have lost your PAY BY PLATE MA Invoice, contact the PAY BY PLATE MA Customer Service Center at 1-877-627-7745, select option #1 then option #9.

How does this system work?

There is an overhead toll collection system mounted to a gantry, a frame structure raised on side supports over the roadway.

As a motorist travels under a gantry system, the cameras mounted at the top of the gantry captures the license plate and the vehicle's registered owner is billed the toll due by mail. If the vehicle is equipped with an E-ZPass transponder the toll will be automatically charged to the E-ZPass account the transponder is registered to.
