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.

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 the gantry system, either
• an E-ZPass transponder is read and the toll is automatically charged to the E-ZPass account that the transponder is registered to
• or a photo of the license plate is taken and the registered owner of the vehicle receives a PAY BY PLATE MA invoice in the mail. Commercial customers will also see a 50 cent surcharge per toll.

Tolls are now collected electronically; motorists 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.

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.


A PAY BY PLATE MA invoice is mailed to the registered owner of a vehicle traveling on a Massachusetts AET roadway without an E-ZPass transponder.

Several 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.
