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.
