Will users be forced to listen to advertising?


This service comes at no cost to taxpayers or callers, and will be underwritten by the integrated marketing components. Users will hear a short sponsorship message when they call 511. It's really no different than listening to the radio - "this traffic report brought to you by XYZ Company."

What about folks who don't want to call 511?


MassDOT is working more closely with radio stations and TV stations to make sure they have the most accurate information possible about the conditions of our roads. The radio is where most drivers choose to get their traffic information, so these types of partnerships make sense.
Top

Is the state encouraging drivers to use their cell phones?


No, MassDOT is not trying to encourage drivers to use cell phones while driving. We want to make the service so convenient and easy to use that drivers use it before they start driving. 511 is also a great option for passengers to call while the driver focuses on the road.

Will callers be able to talk directly to MassDOT staff?


This phone number isn't meant for customer service issues, but callers can report road incidents or conditions that our operators need to know about.
